Hi guys. I have a 2011 MBP that has been pretty decent, but seems to have some issues that I can't solve. Basically, once every 4 or 5 days (give or take), the computer will freeze requiring a hard restart. Sometimes this will happen when I'm in the middle of using it. Other times it will happen overnight after I've put the display to sleep (computer still on, just the display is sleeping). There is nothing in the Console that suggests any errors happening. The Console entries simply cease between the time when the computer freezes and whenever I restart it. There is nothing I can do to replicate the situation with any measure of consistency. Sometimes it happens when I'm doing something...sometimes when I'm doing nothing but browsing websites. System is never under load when it happens (somewhere between 50C and 70C). Memory use has been normal. I've run memory tests (in Single user mode) and HDD tests. I've verified my disk permissions with Disk Utility and Onyx. Nothing special seems to be happening in Console. I'm not using any software that I didn't use on my 2010 MBP, which had no issues. Yet and still, the freezes come. They are rare, but frequent enough and unpredictable enough for me to worry whenever I'm doing something for business. I shouldn't have to think about when my next freeze is going to come. Any ideas on where else I look to trouble-shoot? Nobody wants to use a computer that is unreliable for any reason, you know? I've considered doing another format and reinstall of OS X (I did that once already), but I'm not excited about doing it again and again, I'm not using any unique or special software that I wasn't using on my 2010. Just basic stuff like iStat, smcFanControl, gfxCardStatus, BettertouchTool, Quicksilver and LittleSnitch. Ideas will be appreciated.
