Mac themes??

Hello. I'm new here (actually this is my first post). I was browsing some of the themes here and I noticed some were for PC and some for Mac. What makes a theme PC or Mac specific? And is there a way to convert a PC theme to a Mac theme?

How/where is it indicated exactly that the Theme is for PC or Mac? Usually Themes should work on both Windows and macOS. So not sure if the download might perhaps include some additional files (with custom shortcuts, etc.) which are macOS specific ... Can you please post links to some of these Themes as example.

As far as I know, the are all useable on both. I'm on Mac and have never downloaded a theme that didn't work.

Good find, that's the first time I've seen a REAPER theme be OS specific. I have no idea why.

Yeah, my first guess would also be that the 'Mac'-Themes are optimized for Retina/high resolution displays.
