Hi, just incase you do what I did... (was not thinking properly) it does not update in 'Safe Mode' though does update normally, read the instructions on how to update before you shut down. Also there is a Firmware Restoration CD 1.8 that can be downloaded first should Mac Pro EFI Firmware Update 1.4 not fully complete. (this too has been posted on Apples website)
