How to upgrade from OS X El Capitan 10.11.6 to Big Sur?
I haven't used my desktop in ages and there are no software updates available.
When i try to download Big Sur directly it says "This version of macOS 11.2.3 cannot be installed on this computer."
In the software description it says i must have version 10.11.5 or later, which i do!
I tried to do a Chat support with Mac but it says my product doesn't qualify for special tech support or something...
Please can someone help me? Thank you very much!!
iMac 27″, OS X 10.11
