I'm a Mac addict and Corel is not compatible. If it were I'd use it but I won't charge platforms just to purchase, yet another, piece of photo processing software
I believe you could install WIN7 OS on your MAC and then run PSP 19.
I use PSP 2019 and love a lot of the features. One is the ability to use Topaz and other 3rd party plugins. I guess I missed why this is any lesser than Elements or other editors. I also love the Discovery support videos on how to do things with it. I recently rented a Canon EOS-R and was a bit surprised that PSP does not yet recognize the new Canon RAW format. I would think they will be adding it, I submitted a support ticket but there is no known date for a release.
