I am not a Mac user, but my friend just tested my game's Mac export on his machine and it works great. He was just complaining about long loading time, but apart of that the game itself works fine.
But what concerns me is that my game's Windows and Linux export takes about 150MB, but a Mac export takes 1.65GB! Is this normal? Are Mac exports so big? Or somethings is wrong on my side?
I'm using latest 0.13 NWjs version (v0.13.2) as every newer one gives me screen flickering issue.
