    Hello, is it possible to install an older Mac OS (e.g. Mac OS 10.14 Mojave) on a new M1 Mac with Parallels Desktop 17 and run 32-bit software on it?

    No. It is not possible

    Thanks, can you justify that? What is your experience?

    Mojave does not run on the M1, and Parallels does not emulate an Intel CPU. So now virtual 10.14 on M1 Macs.

    Wouldn't Parallels be able to emulate an Intel PC so that 32-bit software can still be used?

    Theoretically, yes. Someone from Parallels posted here that they were experimenting with older Intel Windows versions and the performance was bad and the power consumption too high. Maybe they are still working on it and eventually get the performance to a level they are comfortable with, but I wouldn't bet on it. And emulation will definitely make an OS run worse than a VM.
