An owner of a MacBook Pro, are we not? It's a good thing then that you stopped by, because Apple has just issued an update for you addressing stability issues. MacBook Pro EFI Firmware Update 1.5.1 is available HERE if you wish to download

and install right now.

As usual, Apple falls short of giving specifics as to what exactly the Apple MacBook Pro EFI Firmware Update 1.5.1 patches: "About MacBook Pro EFI Firmware Update 1.5.1. This update fixes several issues to improve the stability of MacBook Pro computers," the message from Apple says while MacBook users perform the installation. The company does, however, mention that "after the firmware is successfully applied to your Mac, your Boot ROM Version will be:  MBP21.00A5.B08 or MBP31.0070.B07." Users can then confirm the version of the Boot ROM installed on their computers using System Profiler.

To complete the firmware update process, Apple asks users to follow the instructions in the updater application (/Applications/Utilities/MacBook Pro EFI Firmware Update.app), adding that the updater will launch automatically when the Installer closes. What MacBook owners should take into consideration is that they should not unplug, shutdown, or restart their computer while the update is taking place. Interrupting a firmware update can render the machine "unusable," the company states.

Also, if you are unsure whether your computer needs a particular update, simply download and open the update installer. The installer will alert you if the firmware update is already installed or not needed. An example is available and pictured left (click to enlarge).

As a side note, whenever you are updating a portable Mac, such as the MacBook, MacBook Pro or MacBook Air, make sure that your AC adapter is plugged in. The Firmware Updater application will not run unless the computer is connected to AC power because of the above mentioned warning from Apple - that you should not interrupt the firmware update process under no circumstances.

So, now that you know all this, all that remains for you to do is to update your MacBook Pro's EFI firmware as soon as you get the chance.
