Performing the EFI firmware update to version 2.7 these days, I noticed that my 15" MacBook Pro (bought March 25, 2012) resets for five times before booting effectively.
Even then, I can notice that EFI firmware 2.7 is still available in Software Update.
I tried to repeat the update operation, but still no joy. It seems like the update couldn't take place for some reason.
I can't figure out why.
