Upgrade OS on iMac 10.13.6
My iMac is running High Sierra 10.13.6. Is it still possible to upgrade the OS? and up to which version?
iMac, macOS 10.13
Back up your data, check your applications for compatibility, and depending on which iMac model you have, click on Mojave, Catalina, Big Sur, or Monterey. It needs to be at least a 2012 one to run a newer OS.
