Apple has released a “perfomance upgrade” for its Snow Leopard operating system. According to the support document released along with the upgrade it’s supposed to addresses intermittent hard drive related pauses reported by a small number of customers.
The hardware possibly effected by the issue includes:
MacBook Air (Mid 2009), MacBook Pro (17-inch, Mid 2009), MacBook Pro (13-inch, Mid 2009), MacBook Pro (15-inch, Mid 2009), MacBook Pro (15-inch, 2.53GHz, Mid 2009), iMac (20-inch, Mid 2009), MacBook Pro (17-inch, Early 2009), MacBook (13-inch, Early 2009), MacBook (13-inch, Mid 2009), MacBook (13-inch, Aluminum, Late 2008), MacBook Air (Late 2008), MacBook Pro (15-inch, Late 2008), iMac (24-inch, Early 2009), iMac (20-inch, Early 2009), Mac mini (Early 2009)
So open up software update and get to installing. Read here for more information.

Thanks for the heads up, Larry. I’ve had some stalls on my 17″ MBP which were confounding me, and hopefully this will clear them up.

I wonder if “performance update” is a euphemism for “won’t delete your data on a whim”

I just installed SL last night (I had to do a total reformat because my MBP had been updated MANY tines and was still on a pre-GUID partition scheme). LOL. I can’t wait to see what this update does now. SL is nice, overall, though!
