I just recently purchases TS3 and downloaded it via Origin.
When I opened the launcher for the first time I was prompted about a new update. When I chose to update the game - it just opened a bunch of TS3 windows and said there was an error and shut all of them down.
Now when I try to update the game it either does the open-windows-and-error process or doesn't load at all. Same thing with CC - it get some error about checking the Log. I've been searching all over for a solution but I can't find one.
Also, I have a Mac.

Hello,
Have you tried reinstalling origin? Also, do you know if your drivers are up to date? If neither of those two solve your problem, check out this posting that Crinrict posted.

You should always manually patch the game. Full instructions on patching here.
Move your CC/Mods out, patch following the link and see if that helps.
