Did you iMac come with macOS Catalina pre-installed? If so, you will not be able to downgrade to an earlier version of macOS that still supports running 32-bit apps ... and, if that is the case, you still have a few options available to you to do so.


Those are:

  • Use a VM manager, like Parallels or VMware, to run a VM of an earlier macOS or OS X release.
  • Use another Mac that is running an pre-Catalina release.
  • See if the author of the gaming software offers a 64-bit version.
