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.

Early 2010 MBPs? Maybe I missed something, but afaik there are only mid-2010 MBPs. As firmware updates are no joke, why not clearly state, say, MBP5,3 or MBP6,2? One can easily check in System Profiler/System Information.

As firmware updates are no joke as you say, one should always rely on Software Update to provide necessary FW updates. If one doesn't appear, then it doesn't apply to your machine. Also, a downloaded FW update will not run on an incompatible machine, instead providing an error that the update doesn't apply to that machine.

Definitely. But is this a good reason for devising "early 2010 MBPs"? Apple did, not MacUpdate: http://support.apple.com/kb/DL1492 Can see no point in messing things up.

Here you can find if this update is realy for you: http://support.apple.com/kb/HT1237 As I see this has to do rather with your Model identifier (i.e. MBP 8.8), than your Mac OS version.

Pretty sure he means what he said. It's been the command key since my first mac 20 years ago and still is on my MBP. My MBP doesn't even have an  key.

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

Wouldn't download properly from my software update which is unusual. Had to get it here. I feel like I've had this issue for months if not years.
