Steam user here on Mac OSX 10.5.8 -
When I click 'play' on steam, I can see the SK icon pop up on my dashboard for about half a second before auto-quitting. It just shows up then disappears. I have tried reinstalling the client. Still happening.
This error does not happen on my PC with Windows.
Any help appreciated.
Im on a mac too with steam and am experiencing the same "open -> quit" problem, haven't been able to find a solution yet though believe it is related more towards the new update then the steam client since this is happening with my non-steam client too.
