Mac Pro EFI Firmware Update 1.5

Apple has released Mac Pro EFI Firmware Update 1.5, which it recommends for all Mac Pro (mid-2010) models. The update fixes an issue that prevented the firmware password prompt from appearing, along with a more esoteric issue where the Boot Picker wouldn’t appear when you’re connected to an Ethernet network without DHCP enabled. Apple’s instructions for installing the firmware update are to shut down after the installation completes, and then hold down the power button until its light flashes or you hear a long tone. As always, Apple urges you not to unplug, shutdown, restart, or disturb your Mac during the firmware installation process. (Free, 1.96 MB)
