Wepeel's post in PC Toolkit on Mac (via Wine) was marked as the answer
You don't need the Wine version that was posted here (it never worked that great anyway).
All the info you need to get the Toolkit running on Mac can be found here:
I would suggest sticking to an older version of the Toolkit for the time being, as some people have said that the newest 2 versions have been causing problems.
Personally, I use v18.104.22.168-406125e4 without any problems.
