The Mac Pro earns a 9 out of 10 on our repairability scale (10 is the easiest to repair):

The opening procedure couldn’t be easier.

Basic repairs and upgrades can be performed with standard tools or even no tools at all.

Major components are highly modular and use industry-standard sockets and interfaces, making replacements and upgrades a snap.

Apple provides some step numbers and diagrams right on the device, and publishes free repair manuals for some repairs to help you get it right.

The SSD cards are modular, but custom-made by Apple, complicating replacement.

If you need a replacement part that’s not on Apple’s limited list of approved repairs, you’ll likely pay a dizzying price—if you can find them at all.
