Hi,
I'm having trouble upgrading from 4.1 to 5.1 on my early 2009 Mac Pro running El Capitan.
The Mac Pro 2009-2010 Firmware Tool seems to work fine with the MacProEFIUpdate.dmg and after rebooting, holding the power button and hearing the beep, the system report still says 4.1. I've tried disabling SIP, but it's still not working.
I'm wondering if it might be something to do with my video card? I read that these need to be EFI cards but I assumed this card was since it was the official...
