The forum isn't dedicated to mac. But there have been more issues specific to macOS than Linux or Windows, primarily because I don't use mac and it's been harder for me to fix those issues.
I estimate that we have around 80% Linux users, than only 20% mac and windows users. I know this because of web statistics, e-mail I receive and issues reported on GitHub, etc. It's also mostly advertised through Linux distros and web sites reviewing linux software.
