Updating firmware on macbookpro

Apple today released Mac Book Pro Flash Storage Firmware Update 1.0 for the 2015 Mac Book Pro, which fixes a storage firmware issue that could cause data corruption in rare cases.

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

I’ve tried that from an OS X I installed on an external USB drive with no success. Isn’t that the root of the external USB hard drive file system?

Well, and after a long weekend searching and trying different solutions (even bless), a friend of mine who knows a lot about Apple stuff mentioned the undocumented Hey there, I just wanted to let you know that I was able to recover thanks to your post from the same issue that you described.

I guess I need to ask someone at Apple which one would be safe for me, but I thought I’d post the question here, in case anyone moseying through saw & knew the answer. You could even try and extract your own firmware and flash that, as I think that’s only a backup location for the firmware (but i’m not 100%) so it shouldn’t be broken. Good luck I’ve just been doing a little research, and by going to “About This Mac” I’ve seen that the last installed EFI Firmware was indeed the package shown there for the 5,3, so I reckon I should be good to install that one. Hey pubmem, I just want to thank you for your post.

Cheers again for this article — I’ll let you know how I get on (once my courage has picked up enough to to start ‘fixing and improving’ things again! I was affected by this too and went to the apple store today where they suggested to replace the mainboard for 400€.

i doesn’t actually do an upgrade every reboot just the message.
