Re: Game Frozen, Can't Quit

@punkbees  Try cmd-optn-esc to bring up the Force Quit menu, then select Sims 3 from the list and force quit.

If that doesn't help, open the Activity Monitor (in Applications > Utilities), click on the Sims 3 entry, click the X in the upper left corner of the window, and click Force Quit.

As a last-ditch effort, you can always restart your computer, the option under the Apple icon in the upper left corner of your screen.  Make sure that the box to reopen windows is not checked, so the computer doesn't try to launch Origin and Sims 3 after rebooting.
