Known Issues (Current Release)

Known issues in UAD v8.0.1

  • The initial release of UAD v8 software (UAD v8.0.1) has the known issues listed in this section.
  • Known v8.0.1 issues in this section will be improved in a future release.
  • Important: The information in this section applies specifically to the current v8.0.1 release and supersedes related information on this page.

System sleep and Thunderbolt device hot-plugging are incompatible with this release

  • UAD v8.0.1 is incompatible with system sleep and connecting/disconnecting Thunderbolt devices when the computer is on. This will be improved in a future release.
  • Required: Connect and power on all Thunderbolt devices BEFORE powering on (starting) the computer. Disconnect and power off all Thunderbolt devices AFTER shutting down (powering off) the computer.
  • To disable system sleep, open the Energy Saver panel within System Preferences and drag the “Computer Sleep” slider to “Never” (far right position).
  • Note: If Apollo is disconnected while the computer is on, system sound may no longer be heard. This will be improved in a future release. System sound can be re-enabled by option-clicking the Speaker icon in the Mac OS X Menu Bar (at upper-right of screen) and selecting an output other than Apollo from the "Output Device" list.

Apollo Expanded firmware updates require complete system power down

  • This release includes firmware updates. After updating the firmware, the computer and all UAD devices must be fully powered down.
  • Important: After clicking "Load" to initiate the firmware update(s):
    1. Wait for the "Power Down System" dialog
    2. Shut down the computer (power OFF)
    3. Power OFF all UA devices
    4. Power ON all UA devices
    5. Start the computer
    After the above steps are complete, the system is ready for use.

Multi-Unit Cascading with Apollo Expanded

  • Inter-unit wiring is changed with UAD v8. Only a single Thunderbolt cable is needed for each Apollo unit, and no other cables (ADAT, Word Clock, FireWire, MADI) should be connected between Apollo units. See the Apollo Thunderbolt support page or Apollo Software Manual for details.
  • External ADAT input can only be routed into an Apollo DUO/QUAD when the Apollo DUO/QUAD is the designated monitor unit (with UAD v7, external ADAT was routed into the expander unit). This will be improved in a future release.
  • When more than one Apollo DUO/QUAD is used with Apollo Expanded, ADAT inputs are supported with the monitor unit only. This will be improved in a future release.

UAD v8.0.1 ADAT limitations with Apollo DUO/QUAD

  • External ADAT input can only be routed into an Apollo DUO/QUAD when the Apollo DUO/QUAD is the designated master unit. (With UAD v7, external ADAT was routed into the expander unit.)
  • When more than one Apollo DUO/QUAD is used with Apollo Expanded, ADAT inputs are supported with the monitor unit only.

 

About UAD v8 software

New UAD v8 Features

In addition to new UAD plug-ins, UAD v8 software offers significant enhancements for the UAD Thunderbolt platform, including:

  • Apollo Expanded, featuring:
    • Mix-and-match compatibility with up to four Apollo interfaces
    • New Console 2.0 application with over 25 new user-requested features
    • Flex Driver enables custom I/O routes and names at the Core Audio driver level
  • Compatibility with up to six UA devices
  • Simplified UAD authorization (Internet connection required)
  • Apollo Unison technology for new Distortion Essentials Pedals
  • Mac OS X Yosemite compatibility

Simplified UAD Authorization

  • As of UAD v8 software, UAD authorization is automatic (Internet connection required). When the UAD software is updated, authorization happens in the background when the computer is started and/or when the UAD Meter & Control Panel application is opened.
  • It is no longer necessary to manually authorize after updating UAD software; you can begin working immediately.
  • After purchasing a UAD plug-in, the UAD software requires manual authorization. The web store guides you through the process.

Wiring changes with multi-unit cascading

  • Apollo inter-unit wiring is changed with UAD v8. Only a single Thunderbolt cable is needed for each Apollo unit, and no other cables (ADAT, Word Clock, FireWire, MADI) should be connected between Apollo units.
  • See Multi-Unit Cascading below for complete details.

Increased UAD load with Apollo DUO/QUAD

  • UAD v8 software adds two additional cue mix buses and four additional Virtual I/O channels to Apollo DUO/QUAD. The increased channel count results in a slightly higher idle DSP load (when no UAD plug-ins are running) when compared to UAD v7.
  • If a session with very high DSP loads was saved with UAD v7, there may not be enough UAD resources to load the session under UAD v8 without a "DSP exceeded" error. If a the error occurs, UAD plug-in loading will need to be reduced accordingly.
    Note: This issue does not apply with Apollo 16, which already had seven mix buses and eight Virtual I/O channels with UAD v7.

 

Apollo System Requirements

    Thunderbolt Systems

    • Apple Mac computer with available Thunderbolt or Thunderbolt 2 port

Thunderbolt Connections

Connecting Apollo to the computer

  • Connect Apollo to the computer with a Thunderbolt cable (sold separately) using either Thunderbolt port.
  • Thunderbolt 1 or Thunderbolt 2 ports and devices may be mixed and/or matched for any/all Thunderbolt connections.
    Note: All Thunderbolt devices must be connected to the same Thunderbolt port on the computer.
  • Apollo cannot be bus powered via Thunderbolt. The included external power supply must be used.
  • See the Multi-Unit Cascading section for specific instructions on how to connect and use two or more Apollo units together.
  • Universal Audio Thunderbolt devices are tested with authentic Apple Thunderbolt Cables and Thunderbolt Optical Cables by Corning. Using off-brand cables may cause unpredictable results.

Connecting additional Thunderbolt peripherals

  • Thunderbolt peripheral devices may be serially connected (daisy-chained) to Apollo's second Thunderbolt port.
    Note: Apollo must be powered on for the computer to recognize the daisy-chained device.
  • Per the Thunderbolt specification, bus power is supplied to downstream (daisy-chained) peripheral devices.
    Note: Apollo must be powered on for the daisy-chained peripheral to receive Thunderbolt bus power.
  • Universal Audio Thunderbolt devices are officially certified as Thunderbolt compliant and are therefore compatible with other certified Thunderbolt devices when used in the same chain.
  • The Startech Thunderbolt Docking Station is tested in-house and is known to be compatible with UA Thunderbolt devices. This device has an HDMI display output which can be used for an external display to free the second Thunderbolt Option Card port for other devices.
  • All Thunderbolt devices must be connected to the same Thunderbolt port on the computer.
  • The Thunderbolt protocol supports a maximum of six Thunderbolt peripherals per Thunderbolt bus.

Thunderbolt and Mini DisplayPort

  • For general information about Thunderbolt ports and displays, see Apple's Thunderbolt ports and displays FAQ.
  • Apollo cannot be used by connecting it to a Mini DisplayPort connector. Although Thunderbolt and Mini DisplayPort devices have the same physical connector, the underlying communication protocol used by these devices is different.
  • The type of device port can be determined by the icon next to the port. Thunderbolt ports have a "lightning bolt" icon, while Mini DisplayPort ports have a "display" icon. The difference between these ports and icons is shown in the illustration below.

Port Icons

Quick Start: Installation, Registration, and Authorization

Usage Notes

 

Thunderbolt Use Notes

Hot-Plugging

  • Important: Hot-plugging is incompatible with UAD v8.0.1 (current release). See the known issues section for details.
  • UAD v8.0.1 is incompatible with connecting and/or disconnecting any Thunderbolt device when the computer is on.
  • UAD v8.0.1 is incompatible with powering on and/or powering off any Thunderbolt device when the computer is on.
  • Important: With UAD v8.0.1, connect and power on all Thunderbolt devices BEFORE powering on (starting) the computer. Disconnect and power off all Thunderbolt devices AFTER shutting down (powering off) the computer.

System Sleep

  • Important: System sleep is incompatible with UAD v8.0.1 (current release). See the known issues section for details.
  • Disable sleep. Open the Energy Saver panel within System Preferences* and drag the “Computer Sleep” slider (if present) to “Never” (the far right position).
  • To access System Preferences, press the Apple icon in the OS X Menu Bar (upper left of screen) then select the application from the drop menu.

Sleep Disabled

Computer sleep is disabled in the Energy Saver panel within the System Preferences application

Thunderbolt bandwidth

  • Although Thunderbolt has much higher data bandwidth compared to FireWire 800 (dual 10 Gigabit lanes for Thunderbolt 1 versus 800 Megabits for FireWire 800), it is still possible to run out of Thunderbolt bandwidth. This can occur when very high-bandwidth Thunderbolt peripherals such as high-performance RAID storage arrays, multiple Thunderbolt and/or 4K displays, and similar devices are connected in the same Thunderbolt chain.
  • Bandwidth considerations are especially a factor at high session sample rates.

Using UAD-2 Satellite (FireWire model) with Thunderbolt

Note: This section applies to the UAD-2 Satellite FireWire model only. It does not apply with UAD-2 Satellite Thunderbolt.

  • If UAD-2 Satellite (FireWire model) is connected, system sleep MUST be disabled. Sleep is not compatible with UAD FireWire devices.
  • When UAD-2 Satellite is connected (via a FireWire port on the computer or the Apple Thunderbolt to FireWire Adapter) to the same system as a Thunderbolt-connected Apollo, the following conditions apply:
    1. UAD plug-ins in the DAW loaded on UAD-2 Satellite stream via FireWire, while those loaded on Apollo stream via PCIe.
    2. FireWire tuning with the UAD Bandwidth Allocation parameter is applicable for UAD plug-ins running on UAD-2 Satellite. Since UAD plug-ins in the DAW that are loaded on Apollo still stream via PCIe in this configuration, FireWire tuning is applicable only for those UAD plug-ins running on UAD-2 Satellite.
    3. A minimum processing buffer of 512 samples for UAD plug-ins in the DAW applies for UAD-2 Satellite.
  • Realtime UAD Processing is always available for Apollo's inputs via the Console application, regardless of configuration (even when I/O buffer values are high and/or when UAD-2 Satellite FireWire is connected).

 

General Use Notes

Sample Rate Changes

  • For optimum results when using Console without a DAW, perform sample rate changes within the Console application (instead of within Mac OS X's Audio MIDI Setup application).
  • For optimum results when using a DAW, perform sample rate changes within the DAW itself (instead of the Console application or within Mac OS X's Audio MIDI Setup application).
  • For optimum results when Apollo Twin's current sample rate is different from the sample rate set within a DAW session, change Apollo Twin's sample rate within Console to match the sample rate of the DAW session before loading the DAW session.

4x Sample Rates Support

  • Console's AUX 2 is unavailable at sample rates of 176.4 kHz and 192 kHz
  • Multi-unit cascading is unsupported with sample rates of 176.4 kHz and 192 kHz

DSP Usage

  • Apollo uses DSP and memory for its internal DSP mixer. Therefore, the UAD gauges show some idle resource usage even when UAD plug-ins are not loaded.
  • As compared with UAD v7 software, idle UAD resource usage is increased slightly with UAD v8 due to increased channel counts in the newer software.

UAD Presets

  • When logged into the computer under an account that does not have administrator privileges, saving UAD preset files via the UAD Toolbar (via the small folder icon below each UAD plug-in interface) will result in an "Unable to save preset file" dialog. If this occurs, either log in with an administrator account, or use the DAW's preset management tools.
  • When loading and saving UAD presets within Console 2, using Console 2's improved preset management tools are recommended instead of the UAD Toolbar.

External Word Clock

  • To set Apollo to sync to external Word Clock, the setting must be made within Console. If the setting is changed from within the DAW's control panel, the change may not actually be activated even if the DAW indicates the setting is changed.

 

Apollo Console Notes

Console Application

  • Realtime UAD Processing with UAD plug-ins in Console uses DSP differently than when UAD plug-ins are used within a DAW. To maintain the lowest possible input latency, UAD plug-ins used on a single Console input are “chained” and must be processed within a single DSP chip. Therefore, it is possible to get a DSP/PGM/MEM limit exceeded message even though the UAD gauges may indicate there is plenty of DSP/PGM/MEM available.
  • Loading Console sessions from differing Apollo hardware models allows the session to be opened as offline.
  • Console sessions (and Console Recall plug-in sessions) created in Apollo Thunderbolt software cannot be loaded with Apollo FireWire software and vice-versa.
  • Console Session files (configuration presets) saved within Console will not be saved if the "/" (forward slash), "\" (back slash), or "?" (question mark) characters are in the filename. Avoid these and other special characters when saving Recall files.

 

DAW Application Notes

What is the lowest hardware buffer setting I can use with Apollo for stable operation?

The audio interface hardware I/O portion of Apollo can run at any hardware buffer setting that is stable within the DAW itself. Results may vary as a result of how much the DAW session stresses the computer system. This can be influenced by:

  • How many processor-intensive native plug-ins (such as virtual instruments, convolution reverbs, etc.) are in the session
  • Track count and sample rate
  • Processor speed and overall power of the computer

When UAD-2 Satellite (FireWire model) is connected to the system, UAD plug-ins used within the DAW run at a 512 minimum buffer size in order to operate reliably. Apollo’s dynamic buffering enables lower hardware I/O buffer settings (256, 128, 64 etc.) while maintaining a stable 512 buffer for UAD plug-in processing in the DAW.

The buffer size for UAD plug-ins used within the DAW is equal to the DAW’s hardware I/O buffer setting. Additionally, LiveTrack mode can be used with Thunderbolt (except when UAD-2 Satellite FireWire is connected) which lowers latency even further with UAD plug-ins used within the DAW.

Of course, for the lowest possible latency when running UAD plug-ins on live inputs, we recommend using the included Console application to take advantage of Apollo’s unique Realtime UAD Processing feature, where DAW I/O buffering does not apply.

 

Multi-Unit Cascading with Apollo Expanded

Note: This entire section applies only when using more than one Apollo unit in the same system with UAD v8 software.

About Apollo Expanded

UAD v8 software includes Apollo Expanded, allowing Thunderbolt-equipped Apollo interfaces to be freely combined — adding I/O and DSP as your studio grows.

Multi-Unit Cascading: UAD Device Compatibility

  • Click here for UAD device compatibility when multi-unit cascading.

Multi-Unit Cascading: Wiring

Important: Wiring between Apollo units is different with UAD v8 (compared to v7). For a wiring diagram, click here.

  • A single Thunderbolt cable is required for all unit interconnections. Connect one cable to the host computer and one cable between Apollo units.
  • The Apollo unit ordering and the Thunderbolt ports used is not important (e.g., second port on Apollo versus second port other peripheral, device placement within daisy chain, etc).
  • The computer and all Apollo units must be connected to the same Thunderbolt port.
  • Thunderbolt 1 or Thunderbolt 2 ports and devices may be mixed and/or matched for any/all Thunderbolt connections.
  • In the wiring example diagram, the lower Apollo is designated as the monitor (master) unit. Connect speakers (including ALT speakers, if enabled) to the monitor unit only.
  • All Apollo and Apollo 16 units require the Thunderbolt Option Card. The FireWire ports cannot be used.
  • Do not connect more than one Thunderbolt cable between the same two Thunderbolt devices (the Thunderbolt protocol
    is bi-directional).
  • Connecting two Apollo Twin units is not a compatible configuration.

Multi-Unit Cascading: Operation Notes

For complete operating instructions, see the Apollo Software Manual.

  • Monitor Designation: To facilitate the mix bus integration within Console, one Apollo unit must be designated as the monitor (master) unit in the Hardware panel within the Console Settings window. All other Apollo units are expander (slave) units.
  • Monitor Outputs: The monitor speaker system (or systems, with ALT monitoring enabled) must be connected to the outputs of the monitor unit only.
    Note: The monitor outputs of expander units are available as line outputs in the Core Audio panel (within the Console Settings window) and are not affected by the monitor level.
  • Monitor Knobs: The hardware monitor knob on the front panel of expander units, and their surrounding LED level rings, are disabled (except Apollo Twin in remote mode). To adjust the monitor output level, use the front panel monitor knob on the monitor unit, the knob on Apollo Twin, or the monitor level control in Console.
  • Cue Outputs: The cue mix buses can be routed to hardware outputs on the monitor unit only.
    Exception: Cue mixes can be routed to the headphone outputs of any monitor or expander unit.
  • Flex Routing: Inputs in Console can be directly routed (via Output Route menu) only to hardware outputs of the same unit.
  • Multi-unit cascading is unsupported at sample rates of 176.4 kHz or 192 kHz.
  • (Apollo Twin) Designating Apollo Twin as the monitor unit is not a recommend configuration. Instead, designating Apollo or Apollo 16 as the monitor unit is recommended to take advantage of their additional outputs for CUE routing and ALT monitoring.
    Note: Apollo Twin can remotely control the monitor level of the system even when it is an expander unit.

Multi-Unit Cascading: Clocking

Note: All Apollo multi-unit clocking is carried via Thunderbolt. All connected Apollo units always clock (slave) from the monitor unit, regardless of whether Apollo is set to internal or external clock.

  • Internal clocking:
    • When multiple units are connected via Thunderbolt, all Apollo system clocking and clock settings are automatically configured by Apollo’s device drivers.
    • Apollo's clock setting must remain on INTERNAL unless specifically clocking to an external (non-Apollo) device.
    • When Apollo’s clock source is set to INTERNAL, “EXT” will illuminate on the front panel hardware of the expander units.
  • External clocking:
    • Important: When slaving to an external (non-Apollo) clock, connect the external clock source to the monitor unit only.
    • All expander units are automatically configured to use the external clock when Apollo’s clock setting is EXTERNAL.
    • When Apollo’s clock source is set to EXTERNAL, “EXT” will illuminate on the front panel of both the monitor unit and all expander units.

 

About UAD Thunderbolt Software

Thunderbolt PCIe audio drivers

  • UAD Thunderbolt software (Mac only) uses Thunderbolt PCIe audio drivers for all audio I/O and UAD plug-in processing with all Apollo models. PCIe audio drivers provide high-bandwidth, low-latency Apollo performance with all Thunderbolt-equipped Macs.
  • FireWire audio drivers are not included in UAD Thunderbolt Software. Therefore, Thunderbolt must be used for Apollo’s connection to the computer (the Apple Thunderbolt to FireWire Adapter cannot be used to connect Apollo to the computer when using UAD Thunderbolt Software).

Apollo firmware determines the operating mode

Note: All Apollo and Apollo 16 units ship with FireWire firmware from the factory so they can be connected and used with FireWire computers that do not have Thunderbolt ports. Be sure to install the UAD Thunderbolt Software and firmware to enable the latest Thunderbolt features and functionality.

  • Apollo's firmware determines whether the system operates in Thunderbolt mode (PCIe audio drivers), or FireWire mode (FireWire audio drivers). Apollo firmware is contained within the UAD Powered Plug-Ins software installer.
  • To obtain the UAD Thunderbolt Software (and the matching firmware), choose "Apollo & Apollo 16 - Thunderbolt"
    from the "Select your Product" drop menu on the software download page.
  • UAD Thunderbolt Software selection

  • To update the Apollo firmware, be sure to click "Load" when prompted by the UAD software and follow the onscreen instructions.

Important: UAD Thunderbolt Software disables the FireWire ports on Apollo and Apollo 16

After loading the required firmware contained in UAD Thunderbolt Software:

  • Apollo cannot be connected to the computer via FireWire
  • FireWire devices cannot be connected to the Apollo FireWire ports
  • UAD-2 Satellite and other FireWire devices must be disconnected from Apollo’s FireWire ports
  • UAD-2 Satellite and other FireWire devices can be connected to other FireWire ports, such as a:
  • Important: To re-enable FireWire functionality, the Apollo firmware must be downgraded, and this firmware downgrade must be performed while connected via Thunderbolt. See "Reverting to FireWire connectivity" below for details.

Reverting to FireWire connectivity

To reactivate the ability to connect Apollo to the computer via FireWire (and/or to reenable the Apollo FireWire ports), the Apollo software and firmware must be downgraded to a version that supports FireWire.

Important: The firmware downgrade must be performed while Apollo is connected to a Mac computer via Thunderbolt. The firmware cannot be downgraded while connected via FireWire.

To revert Apollo to FireWire connectivity:

  1. Connect Apollo via the Thunderbolt Option Card to a Thunderbolt-equipped Mac computer.
  2. Power on Apollo so it will be recognized during UAD software installation.
  3. Download Apollo FireWire software by choosing "Apollo & Apollo 16 - FireWire" from the "Select your Product" drop menu.
  4. Launch the downloaded UAD installer for FireWire and click through the screens to begin installing the software.
  5. During installation, the UAD software will prompt to downgrade the Apollo firmware. Click the "Load" button in firmware downgrade dialog window to initiate the process.
  6. After the firmware is installed, the "Power Off UAD Device" window appears. Power off Apollo using the front panel switch, then power it back on. The FireWire firmware is now installed.
  7. Click "OK" in the Power Off UAD Device dialog window to allow software installation to finish.
  8. Restart the computer when prompted by the software installer.

Apollo's FireWire ports are reactivated and the unit can now be connected to Mac or Windows computers via FireWire using Apollo FireWire software.

 

About Thunderbolt 2

Apollo and Apollo 16 are compatible with both Thunderbolt 1 and Thunderbolt 2

  • The original Thunderbolt Option Card, and the newer Thunderbolt 2 Option Card, can be connected to Macs that have Thunderbolt 1 or Thunderbolt 2 ports.
  • Thunderbolt 2 technology is designed for backwards compatibility with Thunderbolt 1.
  • Apollo can be connected to Mac computers that have Thunderbolt 1 ports or Thunderbolt 2 ports.

Apple computers with Thunderbolt 2 ports

The following Apple computer models include Thunderbolt 2 ports:

  • Mac Pro (Late 2013)
  • 13" and 15" MacBook Pro with Retina Display (Late 2013) and newer models
  • iMac with Retina 5K display
  • Mac mini (Late 2014)

Thunderbolt 2 compared to Thunderbolt 1

  • The primary benefit of Thunderbolt 2 is to facilitate the use of 4K video displays. In general practice, there are no other operational advantages.
  • Thunderbolt 2 and Thunderbolt 1 have the same total amount of bandwidth (20 Gbps). Thunderbolt 1 has two 10 Gbps lanes while Thunderbolt 2 has one 20 Gbps lane.
  • 4K video requires more than 10 Gbps (but less than 20 Gbps) at video refresh rates higher than 30 Hz. Thunderbolt 2 enables the increased bandwidth needed to deliver 4K video resolutions at 60 Hz refresh rates.
  • Adding a Thunderbolt 1 device to a Thunderbolt 2 chain will cause subsequent Thunderbolt 2 devices in the chain to use Thunderbolt 1 protocol.
  • In general, if 4K resolutions at high video refresh rates aren’t required, Thunderbolt 1 bandwidth is more than capable for even the largest audio production needs.

Enabling 4K video with Thunderbolt 1

With Thunderbolt 1 devices such as Apollo with the original Thunderbolt Option Card, or a Thunderbolt 1 chassis connected to a Mac Thunderbolt 1 or 2 port, it is still possible use 4K displays. This can be achieved in the following ways:

  • MacBook Pro with Retina Display: Use the dedicated HDMI port, which supports 4K resolutions. The maximum refresh rate is 30 Hz in this configuration.
  • Mac Pro (Late 2013): The new Mac Pro features three pairs of dual Thunderbolt 2 ports (six ports total on three buses), and also a dedicated HDMI port. Use a dedicated Thunderbolt bus for 4K displays and a separate bus for Thunderbolt 1 peripherals, or plug directly in to the dedicated HDMI port.
  • Note that 4K displays can be used with Thunderbolt 1 Macs, however the video refresh rate is limited to 30 Hz.

Apollo behavior with the Thunderbolt Option Card

The specific differences when using Apollo with a Thunderbolt connection versus a FireWire connection are:

  1. Data for audio I/O and UAD plug-ins used in the DAW is streamed via PCIe instead of FireWire. Therefore FireWire bandwidth limitations no longer apply, and higher UAD plug-in instance counts can be achieved (within the constraints of available UAD DSP).
  2. The minimum processing buffer of 512 samples for UAD plug-ins streamed via FireWire no longer applies (unless UAD-2 Satellite FireWire is connected*). PCIe can use smaller buffers, therefore latency is reduced for UAD plug-ins used in the DAW.
  3. FireWire tuning via the UAD Bandwidth Allocation parameter is no longer applicable (unless UAD-2 Satellite FireWire is connected*). The FireWire panel in the UAD Meter & Control Panel application does not appear when Apollo is connected via Thunderbolt, so the parameter is unavailable. Similarly, the FireWire bandwidth gauge in the UAD Meter does not appear.
  4. LiveTrack mode is available for UAD plug-ins used in the DAW. When enabled, LiveTrack mode reduces UAD processing latency via PCIe even further. LiveTrack is useful when playing virtual instruments through UAD plug-ins.

*Note: Specific FireWire behaviors still apply when UAD-2 Satellite (FireWire model) is connected. See Using UAD-2 Satellite (FireWire model) with Thunderbolt for details.

    Determining the Thunderbolt Option Card type

  • The type of card can be determined by a visual inspection of the text on the card's mounting plate. The original Thunderbolt Option Card has port numbers silkscreened on the plate ("PORT 1" and "PORT 2"), while the newer Thunderbolt 2 Option Card does not have port numbers, as shown below. Also, the ports are slightly recessed on the Thunderbolt 2 Option Card.

Differences between the two option card types

  • The Thunderbolt 2 Option Card supports the Thunderbolt 2 protocol for use with 4K display monitors.
    Note: This card is fully compatible and compliant with Thunderbolt 1 ports and devices.
  • The Thunderbolt 2 Option Card does not contain FireWire circuitry.
    Important: This card is not recognized by Apollo FireWire software (FireWire audio drivers).
  • All operational differences are summarized in the table below.
