Well, it's fix'd now if you didn't notice.

Nope.avi
hl2 [in my case, hl2_osx] either doesn't start claiming "Failed to take master pipe connection lock," starts up and goes nowhere, starts up and goes to the main menu for GMod before crashing, but none of the options there thus far is "starts up, and runs normally".
Seriously, what the fuck. If this is Garry's doing at all, it just begs the question of "what the FUCK is he doing to cause these problems every time gmod updates, if not poor programming practices?"
