Hi, I've followed speedrunning for a long time but this is the first time I've tried to run a game myself. I play superliminal on Mac as it's the only option I have, does that count for the PC category on glitchless? It would be a shame if I wasn't able to submit my runs because I have Mac instead of PC, but I will respect the mods' decision

Yes! PC includes any OS available to you, including Linux, Windows, and of course, MacOS. That's a completely acceptable OS to run on. Make sure you join the Discord if you have any questions so that's easier for us to answer! :)

Thank you so much!
