Quick-fire questions
Can I replace the Fusion Drive in my iMac 5K 2017?
> Not unless you’re very skilled at tricky internal surgery, as the process requires separating your Mac’s display and moving its left speaker. This is explained in iFixit’s guide at bit.ly/ mac367imacdrive. You almost certainly need to pay a qualified Apple technician to do that for you.
How do I check the last Diagnostics result code?
> Use the About This Mac command in the Apple menu, click on System Report… and select the Diagnostics item at the left, in the Hardware section. That should tell you the last time Diagnostics was run, and the result. M1 Macs running 11.3 may not update this correctly, though, as it’s stored in NVRAM.
Using one external disk to start two M1 Macs up will require multiple authentications when you swap between systems.
