After upgrading to Monterey 12.3.1, I could no longer run CopperCAM with an older bottle of wine. I did try CrossOver - it worked but I just can't see paying a continued fee for a part-time hobby need.
PlayOnMac is a perfect solution! Worked without any trouble - Thank you Developers!!!!
(CopperCAM is a program that prepares PCB's for CNC Milling (been using it 5 years). Here's a link: https://www.galaad.net/coppercam-purchase-eng.html
