Seriously, don’t. Buy a cheap old thinkpad and use that.

Why? Because parallels will break, you’ll upgrade your machine, or you’ll be forced to buy a new version of parallels.

A ThinkPad for $100-200 will do this job very well. Find one that already has an SSD installed. And because you only use it for this specific purpose, you can cut it off from the internet and never install updates.

For the record, I have 27” iMacs in both my garage and shop room. My daily driver is an M1Max Macbook Pro. I like Macs. This is not a good use for them, and you will be a LOT happier if you don’t go this route.
