Will macOS 10.13 High Sierra work with OpenEmu?
I’ve got my old Mac min I’d love to setup as an emulator station and just found this project. Is my Mac to far out of date to be used?
From the commit history, it seems to be that the earliest mention of 10.14 minimum support is from 44acc1d15a825b6cefe8d4fa3445c66b5e24ef19 , which lines up with v2.2.1. Going off of this, I would assume that the latest version compatible with macOS 10.13 High Sierra would be the previous v2.2.0 from Dec 27, 2019. I don't have a 10.13 system to test if that's the case, but I think it's your best bet.
I have followed your tip but 2.2.0 doesn't work on High Sierra, you should instead install 2.0.9 version
