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?

wrldwzrd89 · Sep 27, 2007, 04:38 PM

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.

psychofreak · Sep 27, 2007, 04:42 PM

No problems here (so far)

mac 2005 · Sep 27, 2007, 04:43 PM

Is this update available under the

menu or do I need to download it from the Apple site?

Xeem · Sep 27, 2007, 04:43 PM

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?

Why do people feel the need to vote negative for a firmware upgrade ?????????

Sign of the new Mac Pros to come tomorrow.

Maccus Aurelius · Sep 27, 2007, 04:46 PM

Uh oh, hope it doesn't BSOD when I get home

kevo0822 · Sep 27, 2007, 04:48 PM

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.

eme jota ce · Sep 27, 2007, 04:49 PM

Installed on macbook C2D 2.16 - no problems here, either.

Bad Paper · Sep 27, 2007, 04:50 PM

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.

altcomputing · Sep 27, 2007, 04:52 PM

MB 1.83 Core2Duo: no problems, update was smooth on beta Leopard!

ansalmo · Sep 27, 2007, 04:52 PM

Nothing showing in up in my iMac's software updateother than the iLife and iWork stuff.

Intel Macs use EFI, not BIOS.

Darkroom · Sep 27, 2007, 04:58 PM

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...

kitki83 · Sep 27, 2007, 04:59 PM

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.

thejadedmonkey · Sep 27, 2007, 04:59 PM

I wonder if this will help the Linux scene on the macbook's..

cavemonkey50 · Sep 27, 2007, 05:01 PM

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?
