I’m sorry, but maintaining multiple OS at the same time is beyond my capability at the moment. I’ve tried to support MacOS in the past but it doesn’t work out for me.

I’ve heard a user in Discord manage to run Pixel Composer on Linux using Wine iirc. But I don’t know about the specific or the usability. You can try running the demo with Wine to see if it works out for you. Thank you for your interest in my software and sorry I can’t be of help.
