  1. While I had that update I’ll have to wait and see if it fixes the issue. When I’d wake the Mac from a self induced sleep, it would not wake the drive. I thought it was because the External drive or the enclosure I use as the boot was having issues. It would be fine if I put the “Apple” Mac mini 2009 to sleep and then woke it.

  2. Before any user installs this update, he or she should check to make sure that the clutch is not being let out too quickly on the hard drive. That used to stall my tractor so many times…

  3. Installed the update last night – so far, so good – I was experiencing intermittent but frequent 30 second to 1 minute stalls 10-20 times a day but assumed it was my particular install which used my old crusty 2006 iMac’s files for prefs and apps…

    So far, ZERO stalls!!!! No re-install for me!

  4. I’ve been having 5-45 second stalls particularly in the open/save dialog for over a year (consistant from before & after update to Snow). Assumed I have/had a bad drive. Can’t wait to try this update & see what happens.

  5. I don’t need this update, I need an update to fix my wireless connectivity. Every time it wakes up from being asleep it reads the airport and says it doesn’t have a signal. I turn airport off on laptop, wait 30 seconds and then turn it on and it will show up… what’s up with this? Just started with the 10.6 Update.
