Upgrade mid-2011 21.5" iMac (El Capitan) to High Sierra.
Where to find it & how to do it. ?
Thx for anything that helps
I've been running 10.13.6 High Sierra on my mid 2011 for years.
Using your safari browser only go to this link:
https://apps.apple.com/us/app/macos-high-sierra/id1246284741?mt=12
That should open the app store on the High Sierra download page.
Sorry, but you won't be able to upgrade your Mid 2011 iMac to macOS High Sierra as it is not compatible with that OS version. You would need a 2012 or newer iMac for that.
High Sierra will run on a 2011 iMac. Our 2011 iMac is quite happy with it. It is 10.14 Mojave that requires a 2012 or higher Mac.
High Sierra System Requirements
You can get High Sierra from a link in this Apple article:
Thanks, but it says iMac late 2009 or newer is good.
Opps, sorry about that. I used the info farther down on that article by mistake. The other responders, thankfully, got you the right answer. Not enough coffee this morning ... ugh!
So far so good - it’s downloading it now. How the install goes as good. Thanks for that link.
