OS Upgrade
I have a late 2015 iMac that is still on Sierra 10.12.6 and need to upgrade to a new OS, any recommendations on which one i should get?
Back up your data, check your applications for compatibility, and depending on what you find, click on High Sierra, Mojave, Catalina, Big Sur, or Monterey.
32-bit software won't run in Catalina and newer; download and use Go64 to scan for it. To check general compatibility, click here and look your programs up.
