ammoune78 Posted November 28, 2014 Share Posted November 28, 2014 Hi everyone! I would like to know if there's a possibility to re-flash my MacBook Pro EFI Firmware. I bought this used MBP and i need to flash the firmware because it does not work with the default firmware updater by apple in download section!
