Re: sims 3 64 bit & metal keeps crashing?

@sophtoph4  Please try playing in windowed mode (cmd-enter to switch at the Main Menu or in-game).  If that doesn't help, lower all the settings to their minimums and test.  You'll need to do this at the Main Menu, then quit to desktop and reload, rather than switching in-game.

If none of this helps, please attach your deviceconfig.log, in Documents > Electronic Arts > The Sims 3.  You'll neeed to manually open the folders; the file won't show up in a search.  You can delete your user and computer names, about 25 lines down, but there's nothing else in that file that can identify you.

@paradise12233  Kernel panics are always a bad sign.  If you can, please take your Mac into an Apple Store or a certified to get it checked out.  In your situation, I wouldn't be comfortable doing anything on the computer before someone had examined it.

@kaat31  Thanks for the info.  So you're aware, the graphics chip in your Mac is actually under the minimum requirement for Sims 3.  While that doesn't mean you can't play, it does mean you may have to play on low settings.  Try windowed mode first, and if that doesn't help, try lowering all the settings to their minimum at the same time.  If that helps, you can raise one setting at a time to see which one(s) cause problems.  If you do find a particular setting or settings that cause more crashes, I'd love to know what they are.
