I am trying to upgrade from OS X Yosemite to El Capitain on an iMac from mid 2010, 4GB Ram and 362 GB free HD, but all I get is "This version of OS X 10.11 cannot be installed on this computer" - the button "Learn More" does not offer any help. Please help me understand what it will take to make it work ?
iMac, OS X Yosemite (10.10.5)
Check to make sure your applications are compatible.
El Capitan 10.11 Compatibility information
macOS Sierra 10.12: Compatible Apps
Also check to make sure there is a compatible driver for your printer.
Do a backup before installing, preferable 2 backups on 2 different drives.
Your computer is capable of running High Sierra, so the Mac App Store won't allow a new download of El Capitan on it. If you need the earlier version, start the download on an older Mac or one running 10.7.5 or earlier, or log in with an Apple ID previously used to download it.
