Interestingly enough, only some Santa Rosa machines are affected by this EFI update

Either they've not had many issues or they're still working on them

Yup, no update for me here.

Did you have to update?

I don't get it?

I checked my 2.2Ghz Macbook Pro and I already have that update. Bought in June when it released.

My mid 2007 macbook just got the update via software update at 2.1mb version 1.1

Just got prompted for a MBP update there now.

I didn't have to update

I originally thought it was for the Santa Rosa line, but it's obviously just random models affected.

I did have to install a "MacBook / MacBook Pro File System Journaling" update though lol

I assume this update would show itself in Software Update if my machine required it? I haven't seen anything yet

My MacBook from December last year needed it.

Not really noticed any difference except it's reporting a much higher battery runtime now when not plugged in

Just updated my MacBook.

I can't really notice anything hugely different

It's a firmware update.

The only real difference would be reliability and a slight performance boost, if any
