I have been reading about Mojave and was wondering which of the two ways to upgrade would be best: clean (wipe the computer and start over), or just drop it in the computer and go…
I’m real glad you asked! Almost always, I recommend simply upgrading your existing insulation. Apple’s upgrades have historically run pretty clean, and typically do some nice housekeeping in the process. The only conditions that make me go for a full erase-and-reinstall are a) someone is moving to a new computer and has a burning desire for a fresh start, or b) something is real obviously messed up and no other troubleshooting has been successful.
But there is an implied question here, namely, should you upgrade to Mojave yet?
Short answer: It would probably be fine to do so, but I’m still going to recommend that you hold off for a couple of months.
For iPhones and iPads, the big upgrades usually go smoothly, but on the Mac, unless you really need or want the new features and don’t mind some quirkiness as Apple squashes bugs, it’s best to wait a couple/few months for the new OS to reach its x.2 or x.3 update.
Mojave has been working fine for me, and there are no reports of big problems. I think it’s one of the nicest upgrades to the Mac in recent years, specifically because Apple gave Finder some long-overdue love. The new screenshot features that mirror what iOS got last year are also really helpful.
But as this article demonstrates, some folks have encountered minor issues. They have quick enough fixes, but if you count on your Mac to run smoothly without having to engage someone like me, might as well wait a bit!
