Updating firmware on macbookpro

Now I have it working again and saved the money thank to our post and the instructions in Comment #30 on the bugreport.

Cheers jakommo I ave done this on my 5.5 it works better now, it did the update, and restarts normally but every restart i get a message firmware update completed successfully, i click ok and everything is ok is there a way to disable this message?

Before that turning them in to the apple store seemed like the best bet, so this has been a pretty big life saver!

Keep up the good work 😉 Paul Hi — thanks for this post — I’m one of the people from the bug report, although I haven’t been able to use your solution, yet, as there don’t appear to be any firmware upgrades for my model of MBP (5,4) in the link you provide. Don’t know if that works, but maybe someone with the same model could extract the firmware file (should be located in the EFI partition which is mountable (as msdos) from the terminal at the APPLE/EXTENSIONS path) and you flash that one.

Apple recommends that all customers who have a mid-2015 Mac Book Pro download and install the update.

I’m not sure, but my gut tells me that the Ubuntu install fried the firmware.

I’m guessing using bless to reflash the Mac Book is the right solution.

It can be acquired from the Mac App Store on affected machines or directly from Apple's support site.

The mid-2015 Mac Book Pro includes all 15-inch Retina Mac Book Pro models that were released in May of this year.
