What do?
Things I've done before this happened:
-Defragmented game files
Dunno if this might've led to this issue.
Things I've done to resolve this issue:
-Played "The waiting game" (Waited forever for it to get to "Sending Client info", never happened)
-Followed the guide
here under the MAC section of the guide.
I also use a mac but I still have the same file directory locations for steam and tf2 as a PC user.
Ex:
Windows: C:\Program Files\Steam\SteamApps\[SteamUsername]\Team Fortress 2\....
Mac: Users/[username]/Library/Application Support/Steam/SteamApps/[SteamUsername]/Team Fortress 2/...
Halp pls.
