Brilliant! Fixed the incessant flickering on MBP that's been going on for months now (was getting ready to bring it in since it's still under warranty...but kinda sucks living without a computer for a few days, as sad as that may be). In any case, install without a hitch and there has been no flickering of the display since - it's like having a new computer!

Would install into Core Service Folder on my Early 2011 MPB 13", but the firmware update process after reboot would never initiate. Worked fine on an Early 2011 MBP 15", however.

Would install (into Core Services Folder) but not update my MBP 13"" Early 2011's firmware. Did work on a 15" Early 2011, though.

Installed without a hitch. Check out the new About This Mac in the Apple Menu!

Noticed you can now select Wifi network when OPTION booting, even on Snow Leopard. Firmware update went without a glitch. Don Montalvo, TX

As always, rely on Software Update to determine your machine's eligibility for this, or any, update. SU installed the MBP Software Update before it would even show this firmware update. Installation went without a hitch. Boot ROM on my 17" went from MBP81.0047.B04 to ...B0E. The AMD EFI driver was updated from 01.00.504 to ...521.

Just installed the update through Software-update. No problems whatsoever! ;-)

For some (magical?) reason, the update just showed up in Software-update! ;-) I will install it and let you guys know how it went.

No problem here with 15-inch MacBook Pro mid 2010. Update made through Software Update (in Safe Boot), with all external devices disconnected.

I have a MacBook Pro 17" Core i7, but this firmware update does not appear in Software-update. If I manually download the .dmg file, the installer tells me that my system is not supported... Why?!

Wake from sleep is quiet but restart still causes it. Well, a partial win.

Before I installed this update, Windows Vista on my MacBook Pro (Mid 2007) would not realize that it was plugged in to wall power (the battery would charge, but Windows would behave as if it were running off the battery) until I unplugged the MagSafe power connector and plugged it back in again. After I installed the update, the computer successfully recognizes the power plug.

Applied the update. After my system had been up for about half an hour, all sound output stopped working. Any application that tried to output sound would freeze and require a manual kill. Couldn't even get to the Sound prefpane. I tried restarting coreaudiod, no effect. I slept and unslept the machine, no effect. I eventually rebooted, and the problem resolved. I have never seen this happen before this update, so I suspect it may be linked since it happened right after I updated. Has anyone else had odd audio freezes like this? I did zap my PRAM after the firmware update.

This Updater 1.2 is a mess. My MacBook Pro is unusable since installed. I' ve already used the restoration cd without any effect. After a week working every solution I'm stuck with system 10.4.6. If I upgrade to the next level the machine does not boot. Please Advise.

update kills built in airport card. have not yet figured out how to fix!

Is this for the first or second generation of MBP's?

Install went as described, no issues as of yet. I hadn't had any wake from sleep issues so I can't comment on that, other than to say everything still works as it should.

oh well this firmware can't be update for my macbook pro.don't know is because i already have a firmware 1.0.0 or i do not use a proper way update.should i hold the button untill the sound beep or see the flash the release if any one could send me a email.. novex1984@gmail.com thanks...

@(*#$@**( , I am really upset. I NEVER heard my processor whine until I installed this update. Now I hear it anytime I do something as little as move my mouse. Any ideas how I could revert to 1.0?

I tried to update my MacBook Pro's firmware, but it would not do it. I applied the previous firmware update though, so maybe I am alright for now. I am not going to force it, since everything works as it should. This might be some firmware update fix for those special cases that might have had problems with the revious one... not really sure though.

What's this one do? The last one made my computer run much faster. Plus, I can run Windows now :-P.

Installed without issue. I wasn't having problems before so I am not sure what this did, but happy to avoid problems in the future.

Awesome. Fixed my MacBook Pro "processor whine", the only issue I was having. Thanks Apple!
