U2412m macbook. The Mac Pro introduced in 2019 has eight PCIe slots:
- Four double-wide slots
- Three single-wide slots
- One half-length slot preconfigured with the Apple I/O card
Mac Pro includes one or two Radeon Pro MPX Modules that occupy slots 1-2 and slots 3-4. You can choose your MPX Modules when you order your Mac Pro or order them separately from Apple. Learn how to install PCI cards in your Mac Pro (2019).
Apple AMD Radeon MPX Modules
Apple currently has four different Mac Pro Expansion (MPX) Modules that contain AMD Radeon Pro graphics processing units (GPUs). Radeon Pro MPX Modules can use slots 1-2 and slots 3-4, and you can install one or two of each module:
- Radeon Pro 580X MPX Module: one module only
- Radeon Pro W5700X MPX Module: one or two modules
- Radeon Pro W5500X MPX Module: one or two modules
- Radeon Pro Vega II MPX Module: one or two modules
- Radeon Pro Vega II Duo MPX Module: one or two modules
You can use Radeon MPX Modules along with other third-party PCIe graphics cards. If you use Boot Camp, using a Radeon MPX Module and a third-party AMD graphics card isn't supported when your Mac is using Windows. Learn about using AMD graphics cards with Microsoft Windows on Mac Pro (2019).

Mac Pro comes with the Apple I/O card, which has two Thunderbolt 3 ports, two USB-A ports, and a 3.5mm headphone jack. The Apple I/O card comes preinstalled in slot 8 and can't be installed in another slot.
Third-party PCIe cards
You can install many different PCIe cards in your Mac Pro, such as fibre channel cards, fibre networking cards, and pro video and audio interface cards. The PCIe bus on your Mac Pro provides up to 300W auxillary power. If your PCIe card requires additional power, such as a GPU, use the Belkin Aux Power Cable.
Mac Pro supports the same GPUs that are supported by external graphics processors (eGPUs). If you use Boot Camp and want to install a NVIDIA card to use in Windows on your Mac, don't install the card in slot 2. Learn about using AMD graphics cards with Microsoft Windows on Mac Pro (2019).
Some older PCI cards might use 32-bit Option ROMs that aren't compatible with your Mac Pro. If you install a PCI card that uses 32-bit option ROMs, your Mac Pro might not start up correctly.

If you want to add additional storage, you can install a third-party RAID card, such as a SAS RAID card, or you can install the Promise Pegasus R4i 32TB RAID MPX Module in one of the two MPX bays. If you use Boot Camp on your Mac, Windows doesn't support Apple software RAID volumes.
Pci Usb 3.0 Card Mac Pro
These instructions are intended for machines that have had a PCI USB card installed after Mac OS installation has occurred, or one running 9.2 without built-in USB ports. The extensions that come with 9.2 have a bug, causing them to not work on Macs without built-in USB. The card and devices plugged into it will appear in System Profiler but will not function, and do not disappear until the machine is restarted.
In 9.1 you could also run the installer again, select Add/Remove, and add in USB Adapter Card Support. This is located in Mac OS 9.1>Network & Connectivity when doing a customized installation.
You will need
- A Macintosh with a working Mac OS 9.1 or 9.2 installation (See note 1 for prior versions)
- One PCI USB Card that’s OHCI compliant, installed in the Mac. The vast majority of PCI USB 1.1/2.0 cards support OHCI.
- Theoretically any OHCI-compliant card will work, but certain configurations are problematic (See note 2)
- Note that a USB2.0 card will not work at 2.0 speeds as OS8/9 do not support EHCI
- Mac OS 9.1, either a retail CDROM or the 9.1 update
- Insert your OS 9.1 disc or extract the 9.1 update and open the “Installation Tome” file
- This is located in Software Installers/System Software/Mac OS 9.1
- Extract these files from the tome, placing them on your desktop.
- HID Library
- Serial ShimLib
- USB Device Extension
- USB Mass Storage Support
- USB Software Locator
- USB Support
- Skip to step 4 unless you’re running 9.2. You’ll need to remove the preinstalled versions of these files from your Extensions folder (in your System Folder.) Create a folder on your desktop and place them inside.
- Drag the files you extracted onto the System Folder. You should receive a dialog box asking you to confirm placing them in the Extensions folder, click OK. Alternatively you can place the files directly in the Extensions folder.
- Reboot. USB should now be working. You may trash the extensions you removed (if on 9.2)
- Apple provided USB Adapter Card Support 1.4.1 as a separate installer for 8.6-9.0. You may still be able to use the versions extracted from 9.1, however.
- All OHCI cards are supposed to work.
- I’ve had the best luck with NEC, Lucent, and OPTi-based cards. I’d stay away from VIA
- I could not get any USB 2.0 cards to function in a PowerMac 6500. I suspect this might have something to do with PCI 2.2, but I’m not sure. Please comment with your results.
