Why I can't get out of EFI firmware update 2.7 on my MacBook Pro? 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.
Sometimes 'Software Update' fails and you are stuck with an incomplete update if this happens you can try to download the update as package direct from Apple (MacBook Pro EFI Firmware Update 2.7)

Install the package, maybe this will fix the problem.
