Upgrade through Mac App Store or clean install?

[Nubben]

Hi All,

Has anyone had an issue upgrading to Sierra from El Capitain (or other Mac OS) through the "upgrade" feature in the Mac App Store rather doing a clean install?

Many thanks!

A lot of people have had issues upgrading to Sierra, so I'd advise a clean install.

No issues here going the upgrade route. I've done it on two MacBook Pro's and both went perfectly. Just to be on the safe side, you should do a Time Machine backup first. But I really wouldn't think twice about an Apple upgrade. It isn't like a PC with Windows that just gets slower with every update/upgrade. Apple's upgrades/updates have always been very reliable and solid for me. About the only issue I've ever encountered on an Apple Mac OS update is on restart during the update you might get an error where it won't restart properly, in which case you can restart holding the Alt key so you can select the MacOS Upgrade icon startup disk. After that, it will reboot on its own just fine.

A lot of people are simply upgrading and it works great. They just don't advertise it to the extent that people with issues do.

I chose to do a clean install just because it's a good opportunity to clean out some old stuff and start fresh (upgraded through Appstore in the last couple iterations of OS X and everything was fine, too). So far it's running great on my 2014 rmbp 15", haven't run into any of the issues people seem to be struggling with in the forums.
