A flurry of updates are now available from Apple’s Support / Downloads web site, one of which resolves several occurrences with mid-2010 Mac Pro computers. The firmware update apparently resolves issues that prevented the firmware password prompt from being displayed, and a problem that prevented the Boot Picker from being presented in certain situations.

Commenting on the purpose of the Mac Pro EFI Firmware Update 1.5, Apple recommends that all owners of a Mac Pro (Mid 2010) computer model apply the update to fix a couple of issues. These are listed as follows:

- Resolves an issue that prevented the firmware password prompt from being displayed - Resolves an issue that prevented the Boot Picker from being presented if Ethernet is connected to a network without DHCP

The technical note continues with instructions and important tips to carry out a proper firmware update.

“To complete the firmware update, wait for your Mac Pro to finish installing and shutdown. Hold down the power button until the power indicator light flashes, or you hear a long tone, then release the power button,” Apple explains.

“A gray screen with an Apple logo and progress bar will appear while the update is taking place. When the update is complete your Mac Pro will startup normally,” the Cupertino-based electronics company adds.

Users are urged to note that the update may take a few minutes, therefore they should refrain from unplugging, shutting down, restarting, or disturb their computer in any way, as the update process is being performed.

More information about firmware updates for Intel-based Macs is provided here, over at Apple’s Support area.
