  1. So far, so good. It has either entirely fixed, or at least mainly fixed my problem on a month-old MBP. I was getting random pinwheels, and my Mac was quite unusable part of the time. Very frustrating. So, I’m thrilled the Apple has done something about it!

  2. Not sure, but I think now my hard drive will not sleep and battery performance has been severely compromised. Tired PRAM and SMC reset but no luck.

  3. Since the update, Windows XP hangs in Bootcamp every time that it tries to ‘sleep’ my 13″ MacBook Pro.

  4. I was having CONSTANT stalls lasting for 10-60 seconds at a time every 15 minutes or so every single day no matter what I did. I was becoming infuriated at the fact that nothing I did seemed to help. Though ever since the update, my 13 Inch MacBook Pro has been running like water. I am extremely pleased. 😀
