One of the great advantages of the Mac is that in addition to OS 10, it can run Windows and Linux. You can set up Spaces so that the Mac OS is in one space and Windows in another!
Just boot Parallels and put it in space 2 then open the Windows program you need. Your Mac OS will be in Space 1 with the Mac program(s) you need, so you can easily switch between them. I’ll bet you could even set up a third space containing Linux!
