> Using 32–bit apps with Big Sur
I recently upgraded to Big Sur, but have now discovered that I need to use an old 32–bit app. What’s the best way to be able to run Mojave as well?
There are two good solutions, depending on whether you want simultaneous access to both the old app and your current ones. If you do, then you should run Mojave in a virtual machine from Parallels Desktop, VMware, or another virtualizer. This is quick to set up, and simplest in Parallels Desktop, which will install direct from a downloaded Mojave installer app, as listed at bit.ly/ mac371macoslegacy.
