Once logged into the root account, re-attempt running the firmware update. Once completed, logout of the root user account and back into your normal account. You may want to launch NetInfo Manager again and re-disable the root user account (again, via the "Security" menu) when finished due to security considerations. Meanwhile, if your update fails with this error: One more thing to try: Some readers have reported that simply deleting the firmware updater and re-downloading it from the original source results in successful application. Your firmware can not be updated."Īfter the required restart, the issue may be bad or otherwise problematic RAM. You can sometimes determine if you have a "bad" RAM module by using the Apple Hardware Diagnostic CD, included with all currently shipping Macintosh models. To use the Apple Hardware Test CD, restart your computer while holding down the C key until the "Loading." icon appears. You can also try using the utility Memtest to check for bad modules, or try simply removing modules one by one until you identify the culprit. Downgrading firmware If you experience a failed update and cannot resurrect your system, try this downloadable firmware restoration disc image. Note that you can only use this to restore the firmware after an interrupted or failed update - not if the update was installed successfully. Startup failure The most egregious problem is one where the firmware update appears to successfully apply itself, or fails part-way through installation and the system subsequently refuses to startup. In many of these cases, even attempts to restore firmware using this downloadable CD image have proven futile, as the disc simply becomes stuck in the machine as it fails to boot. There are a number of methods for ejecting stubborn media in our tutorial "Ejecting media in Mac OS X: Removing 'stuck' CDs/DVDs," but they haven't proven of much use in some cases where systems refuse to power-up at all after the firmware update attempt. Some users have found success with simply pressing the power button and allowing their MacBook Pros to sit for an extended period of time - up to 15 minutes. In some cases, this will cause the disc will automatically eject. #MAC PRO EFI FIRMWARE UPDATE 1.2 DOWNLOAD#.#MAC PRO EFI FIRMWARE UPDATE 1.2 PASSWORD#. ![]() #MAC PRO EFI FIRMWARE UPDATE 1.2 MAC OS#. ![]()
