I updated my rMBP to 10.8.4 a few weeks ago (although I'm sure it wasn't the full 10.8.4 update- more of a small update to 10.8.4 as I think I was already running 10.8.4).
Anyway, since then, safari freezes much more, and every time I close the screen for more than an hour or so, the laptop restarts so when I open it again, I'm back at my login screen. I just opened it after having it in my bag all day, put my password in (it hadn't restarted), turned away for 10 seconds, turned back and it was on the grey screen with the apple logo having restarted!
I've tried resetting pram and SMC but no joy. Anyone have any ideas?
