MBP EFI Firmware 2.7 not installing
Every time I run Software Update runs it tells me I need to install the MacBook Pro EFI Firmware Update 2.7, it downloads the firmware and requests that I reboot. At which point the system reboots but the new firmware is not flashed. Next time I run Software Update I am again told I need to install the firmware, same happens etc...
According to the update this includes version MBP81.0047.27 of the Boot ROM, accotrding to System Information I am currently running version MBP81.0047.B24.
Why is this firmware not installing?
