Firmware update returns and error

I am getting the same message. I have a MacBook Pro: Model MacBookPro2,2. The current firmware version is: MBP22.00A5.B01.

It is supposed to update it to MBP22.00A5.B07. When I run the updater, I get "An unexpected error occurred (0). Your firmware cannot be updated." No idea what is causing this but it is really annoying.

It could be a permissions issue.
1. Disk Utility.
2. Select your boot disk partition.
3. Click Repair Permissions.
4. Restart MacBook Pro.

Try running Firmware again.
Post your results.

If you still have issues, open Console and see what error you are getting. Copy and paste that information here for others to see so that they can better assist you with a solution.

Good luck.

Ok, I've done that
Here's the info that came out on Console:

Does this mean I don't need the update or ...?

I have the same problem...

Me too ! Same error message: "An unexpected error occurred(0). Your firmware can not be updated."

Are there any hind's ?

I didn't get that error, my update seemd to work, but after the re-boot, my wireless mighty mouse AND trackpad both keep freezing every 10 seconds... on the dot!!

Grrrrrrr!!! Suppose it's off to the Apple store tommorow

This firmware update is not for the newest MacBook Pros (with santa rosa-chip). It doesn't even appear to the software update in the apple menu. Don't use an updater if it doesn't appear to you automatically - your mac knows what you need.

Are we all using boot camp? I'm experiencing the same problem but my log looks different:

Just to clarify things:
1-I've a 2.33 Core 2 Duo Macbook Pro, not the newest 2.4 one
2-Software Update launched automatically and notified me about the update
3-The installer was also automatically launched by SU. When I tried to install I received the message posted by me and other users
There's only two possibilities: either there's a problem with our machines or with the updater.
Unless the installer is incompatible with something already installed.

Copy of my post in another thread:

"Hi!
+I saw the other thread with the errors. I have a Macbook Pro Core2Duo 2.33ghz (17").+
+I was all set to do a backup of my machine before leaving the office but figured I should do the firmware update (software update offered me this). Installed the update, shut down the computer. I was holding down the power on button until the flashing light (the one in the lid) followed by a chime. The screen was black over two minutes, no progressbar or grey screen. I shut down the computer to try again. Now my cd rom makes this repeating sound as one would get after rebooting the machine. Black Screen. I have tried using the 1.3 firmware restore method, it accepts the cd but it does not load. Black screen. Have reset the PMU, PRAM. Nothing...any suggestions what to do?+

+I have three major designprojects due till monday.+
+Any advice in the right direction of solving this would be highly appreciated.+

+Thanks in advance,+
+Tom - Norway+

+Im sorry if my english is'nt all that good. "+

I am not using Boot Camp on this MacBook Pro machine but am still getting the same error.

I've just found this on another thread:

"http://forums.macresource.com/read/1/360674

As celliot's post notes:

I did some checking. It appears to be a disk format problem. For those who installed a new disk or reformatted the old. Notice that we get the error message when the utility wants to restart.

Go to disk util. Click on the drive name, then go to the partitions tab. If you then click on options you will see something interesting. three options:

- GUID partition table- use the disk to start up an Intel based Macintosh computer

- Apple Partition Map- use the disk to start up a Power PC based Macintosh computer or to use the disk as a non-startup disk with any Mac

- Master boot record- use the disk to start up DOS. . . . . . .

Anyway, it appears that the way the disk was formatted could impact the disk startup and that might be the problem we are having?"

I checked disk utility and found out that may startup disk has the "Apple Partition Map" format instead of the supposedly correct "GUID partition table" one. Strangely enough because I don't remember reformatting the disk so far.

Actually... if you try to install the update on a SR MacBook Pro, you'll just get a message saying you don't need the update, not an error.

I don't think this is the case as my drive is using GUID partition table (GPT) as you can see from my log above. That or I'm having a totally different issue than others.
