I don't use a Mac, but on my mods I've occasionally been asked whether my mods work on Mac.
Does anyone here use a Mac, and has downloaded mods for the recent Total Wars, eg Rome 2/Attila/Warhammer?

I've found these two guides, but since I don't have a Mac I obviously can't test whether they work myself.
- A guide from a CA staff member for Rome 2 back in 2014/2015
- A Youtube guide that is overly long
