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

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

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
