    Hopefully this will resolve the freezing/lockup issues that new iMac owners have been experiencing.

    - Fixes "my battery charger quit working and, so, the MB must be plugged in at all times?" -- probably not
    - Fixes "my screen perpetually thinks it's closed, and requires an external monitor, or risk falling asleep?" -- probably not
    - Fixes "I installed a ridiculous aftermarket antenna booster, and now my blackbook is dying?" -- probably not.
    - Fixes "My iPhone wants a clickwheel?" -- probably not.

    Note in log: 4th week of September is Apple's Christmas :)

    Improves performance and reliability of Intel Core 2 Duo Processors

    Interesting. How can my 2.1GHz iMac increase in performance with an EFI update?

    Looking at this page, it appears that almost every single Intel-powered Mac got a firmware update today... whoever said Apple is busy churning out updates was right.

    Has anyone run any benchmarks yet to see just how much (if any) of a performance increase there is?

    Well since EFI/BIOS is the interface between the platform and the OS, that would make sense, yes?

    This update includes SR MBPs right? It seems like it should, but Software Update only listed the iWork updates... Maybe I'll restart and see if it makes a difference.

    15 inch SR MBPs only, not 17 inch. See the link in my post above.

    hmm. I have had problems with my Macbook thinking "hmm, now that I'm asleep, I should just reboot. I bet Bad Paper would really thank me."

    Don't know whether this update will fix this problem, but my instinct from years of fixing Winders machines tells me that it's a hardware problem, so here's to crossed fingers.

    Intel Macs use EFI, not BIOS.

    i never had any problems with my iMac Core 2, but maybe 4 times in the past year the CPU fan would suddenly speed up to 5000rpm (from it's normal 1200rpm) and its really loud... it never lasted long, maybe it took a minute to slowly spin down to it's normal state of 1200rpm... anyway, does anyone know why it has done this? when this happened i was never running any intensive apps, and once i wasn't running anything...

    Does this fix the USB HD problems people had, where it would not read, or did but freeze the system until you yank out the USB HD.

    My 15-inch SR MBP didn't see the firmware update, so I manually downloaded it. The installer reported the update wasn't needed, so perhaps all SR MBPs don't need the update. Has any SR MBP owner been able to install the update?
