MacBook Pro EFI Firmware Update 1.5.1: Hits and Misses
Things will never be perfect with computer software, but some moments get funkier than others.
According to MacFixIt, a number of users have reported issues with Apple's newly-released MacBook Pro Firmware Update 1.5.1 software. In given cases where the firmware update itself failing, the Firmware Restoration CD 1.7 has only proven successful for a moderate number of users.
Other issues with the update include issues using the function keys after applying the update, as one site reader recalls:
"Since applying the MacBook Pro EFI Firmware Update 1.5.1, I have lost all functionality of my function keys and can no longer command-tab between applications. MacBookPro 2.4Ghz; 4GB RAM."
The update applies to late-2007 MacBook Pro laptops with firmware version MBP31.0070.B05.
To its credit, the update has been cited as resolving an external display issue for some users wherein external displays went blank after the MacBook's lid was closed for a given amount of time.
If you've seen any major changes, positive or negative, on your end after the firmware update, please let us know in the comments or forums.

Comments
Several of us on late 2007 (2.6Ghz) MacBook Pros were having major problems with "Detect Displays" not working (and as a result, external displays not working correctly) as well as not being able to get the laptop screen back live after a suspend - these problems started after 10.5.2 and the graphics update (not sure which caused it as they went on at same time). Since this EFI 1.5.1 went on we have not had a single reoccurence of these display problems.
