I recently had to re-install the original OS from the discs that came with my MacBook Pro. This installed Snow Leopard and software updates have taken it to 10.6.8
That's all very well, but the latest version of MacOS, known as Catalina, won't run on any Mac older than 2012, and in the case of the Mac Pro, late 2013. Which may well mean that your Mac can't. Maximum Apple supported macOS for your 2011 iMac is High Sierra (10.13.6), but minimum OS to upgrade is 10.8. You will need a 2 step process to get to High Sierra. Jan 13, 2020 OS X El Capitan remains available for Mac computers that can't upgrade to macOS Catalina, Mojave, High Sierra or Sierra, or that need to upgrade to El Capitan first.
However it refuses to upgrade to Lion, Mountain Lion or Mavericks. (I've tried them all a few times).
I have repaired permissions and checked the HD is OK (which it is).
Each time I try to upgrade it takes me to disk utilities. The only way out is to quit and restart in 10.6.8
Does anyone have a tip on how I can upgrade again? It used to run OS X Sierra quite happily.
