9 is M1 native, so that saves a lot of bother I was able to rip out the non-native version entirely.
I live in Brasil, everything has a 97% tax on it after currency conversion, so the base MacMini starts at 8699,00 and goes to 11699,00. Instead of /t:Rebuild, you can alternatively use /t:Build to speed up things even more I use the M1 version of CLion.
