I have a mid-2012 MBA and it's been absolutely wonderful since I bought it... until now. For the last few days (possibly since that most recent MBA/MBP update) I have had an absolutely ridiculous amount of program crashes, general freezing and far slower wake-up times. Anyone else found this? The Apple store in my city has been "open soon" for nearly a year now so I can't go in and get it looked at. It may not have been this most recent update but it's an odd coincidence if not.
