Follow these steps to uninstall and install SSD modules in your Mac Pro. To perform this process, you must have:
Apple Configurator 2.12 or later installed on any Mac that supports macOS 12.4 or later, is plugged into a power source, and has internet access.
You may need to configure your web proxy or firewall ports to allow all network traffic from Apple devices to Apple’s network 17.0.0.0/8. For more information on the ports used by Apple products, see the Apple Support article > Shut Down.
Let the computer cool down for 5 to 10 minutes before you touch the internal components, which may be hot.
Disconnect all cables except the power cord from your Mac Pro.
Touch the metal on the outside of your Mac Pro to discharge any static electricity.
Note: Always discharge static before you touch parts or install components inside your Mac Pro. To avoid generating static, don’t walk around the room until you finish installing the expansion cards.
Disconnect the power cord.
Remove Mac Pro from the rack.
Place the computer on its back, on a nonscratch surface.
Remove the SSD module covers.
Use a T8 screwdriver to remove the two screws.
Reinstall the SSD module cover.
