MacBook Pro EFI Firmware Update 1.5.1

Monday April 21, 2008 3:57 pm PDT by longofest
Apple has released MacBook Pro EFI Firmware Update 1.5.1.

This update fixes several issues to improve the stability of MacBook Pro computers.

After the firmware is successfully applied to your Mac, your Boot ROM Version will be:

MBP21.00A5.B08 or MBP31.0070.B07

You can confirm the version of the Boot ROM installed on your computer using System Profiler.

To complete the firmware update process, please follow the instructions in the updater application (/Applications/Utilities/MacBook Pro EFI Firmware Update.app). The updater will launch automatically when the Installer closes.

Isn't this old news?

Edit: Oops, I guess that last one was 1.5, not 1.5.1
Any difference?

No it's now 1.5.ONE instead of 1.5 and I'm guessing this fixes the problem that screens didn't worked anymore. At least I hope so!

Hmm... Not showing (at least not yet) on my MBP (2.4ghz, mid-2007).

It wasn't showing on mine either (MBP 2.2GHz). I donwloaded it from Apples site and it told me my computer did not need the update.

Not sure why...

I believe that it's only for the 2,1 and 3,1 MBPs. Penryn MBPs carry the 4,1 model identifiers, IIRC.

MBP21.00A5.B08 or MBP31.0070.B07


But that doesn't explain why Jestered's 3,1 MBP didn't want the update (I have the same MBP as you and Software Update pulled it down from the internets for me).

The fact that me and many others with early 2007 models can't wake up the screen after putting their MBP to sleep confuses me as to why the latest firmware update doesn't address my computer's issues, instead it says my computer doesn't need the update?

Why? It definitely needs an update to fix a bloody serious issue!

Yeah, that is what I thought too. I just checked my Boot ROM version and it says I have, "Boot ROM Version: MBP31.0070.B07".

That is very weird. The last firmware I updated was a week or so ago when everyone else did it too. I have no idea how I have the updated Boot ROM version though. Oh and I am the only person that touches my computer so no one else did it. The only other person that could have access to my computer is my wife and she def didn't do it. She can barely turn hers on much less updating firmware on mine.

Weird!

I have this problem, but it is related to the airport malfunctioning, and not connecting properly.
