You can take out the WINEARCH stuff for OSX. There's an issue with the 64 bit ABIs of OSX and Windows; as a result, 64 bit Wine doesn't work quite right. So the default WINEARCH on OSX is 32. The default WINEPREFIX is ~/.wine, so you don't need that either. And finally when creating ~/.wine for the first time, it will install the runners you need, so you don't need to run wineboot.
My procedure (which I've done a TON testing out video configs) is:
- Download Wine (I use Staging 3.19)
- Download winetricks from github
- install brew
- brew install cabextract
- sh winetricks corefonts
- install video stuff
Basically, the procedure from 1.8.
