All running fine for me on Mac (Win10 via BootCamp) - I think the only thing to look out for it that the updater does not seem to work in the UPlay GUI - it fails silently.
Luckily for me I was following the instructions for installing Wolves Of Steel which include finding and running the gu.exe so I never saw it crash.
One problem for me at the moment is the font size used by the map tools (I've got a 15" screen). I've tried searching the forum to see if there's an easy way to increase this or perhaps made the numbers bold - even better would be to increase the offset from the protractor in particular. Perhaps I'm just getting old and need some bifocals, but it appears ridiculously small and difficult to read to me...
Anyone have a thread to point me to or some other advice?
Cheers and Happy Hunting!!!
