I've bought about a dozen (DOS and Windows) PCs and one Mac in the past 40 years, and I still have all of them, but now I want to get rid of one of them: the MacBook. It's a very nice machine, a MacBook Pro 2017 with Retina Display, Touch Bar, 16GB RAM and 1TB SSD, but I just can't come to terms with its random key combinations, its lack of Esc/Insert/etc. keys, and its instability when pushing it with MAMP Pro and a Windows 10 virtual machine running under Parallels Desktop in Coherence Mode. Even trying to give away the Mac is a challenge!
In What to do before you sell, give away, or trade in your Mac Apple gives the following instructions:
- Create a backup (Time Machine)
- Sign out of iTunes (Deauthorize)
- Sign out of iCloud
- Sign out of iMessage
- If you're keeping paired Bluetooth devices, unpair them (optional)
- Erase your hard drive and reinstall macOS
The current page (as I write this) has the Published Date: November 29, 2018 — not so new, but the latest that we've got. Let's take it one at a time:
- Create a backup (Time Machine)
Yes, Time Machine is fine, especially for restoring the whole shebang to another Mac. Better save your data in a format and on a disk that is readable by more than just another Mac.
- Sign out of iTunes (Deauthorize)
I guess they mean App Store, Apple Music, Apple This, and Apple That, too...
- Sign out of iCloud
Yes.
- Sign out of iMessage
And Facetime, too! Apple forces activation of these two at every corner.
- If you're keeping paired Bluetooth devices, unpair them (optional)
- Erase your hard drive and reinstall macOS
Hold down Cmd-R while booting up, erase, BUT:
Here's the hard part: Apple doesn't mention it, but there are two huge stumbling blocks here!
How to handle these, plus additional information that I would have liked to have, is in these posts:
