Complete system freeze Mavericks 10.9.2
Hello guys, I have a Retina MacBook Pro 13.3 from late 2013 and it had been running rock solid until 2 weeks ago or so. Now the operating system is freezing (and I mean a complete hang up that requires a hard reset by pressing the power button), and this is happening at least once a day and randomly. I'm not doing anything extraordinary, sometimes it just happenes when browsing the Web using Firefox (latest version, yes) or Safari, which by the way always crashes when I turn the computer back on, as reported by many others.
I suspect this begun after updating to 10.9.2 as I've never had this happen before since buying the machine. I've been trying to obtain anything useful from the logs and the console app, however the only reported kernel event is a panic from March 5. Don't know if it's relevant or no to this problem. The last time I had to hard-reset the machine was a couple hours ago, and the logs show nothing with regards to kernel panics.
Is there any other place I should be looking for diagnostic / system log information?
Can I rollback to 10.9.1 (I understand I'd be vulnerable to the SSL bug, but right now with 10.9.2 I'm more vulnerable to the smash-computer-against-wall bug out of frustration!)
Needless to say, any pointer to fixing this is more than welcome.
Thank you,
-Enrique
