MacBook Pro :: EFI Firmware Update 2.5 & Booting OS 10.6.x?
Apr 23, 2012
Are there any known compatibiity issues with booting from an OS 10.6.x drive after installing EFI Firmware Update 2.5?I am running Lion (10.7.3) on my MacBook Pro (13-inch, Mid-2010) but have held off installing the firmware update because being able to boot from a 10.6.x backup drive is more important right now than internet-based Lion recovery. If there's no issue booting 10.6.x (and running apps), then I will go ahead and install the firmware update, otherwise I'll wait awhile longer.
Info:
MacBook Pro (13-inch Mid 2010), Mac OS X (10.7.3)

I recently attempted to install the most recent firmware and security updates for mac os x 10.5.8 on my macbook pro 17 inch (purchased about 14 months ago). Computer asked me to reboot, i did, it then gave me instructions for firmware updates.
The screen went dark, and it did its thing, and I returned 10 minutes later. The computer had not rebooted.I pressed the startup key and it gave a long beep. Screen remained dark. Some minutes later it ran the boot cycle, but booted into windows (i have dual boot set up). I can only get into windows now.

I've just set up an Open Firmware Password for the first time. My understanding is that this would prevent booting the Mac from another volume (i.e. an OS X install DVD). After setting up the password and rebooting my machine, I decided to test things out by inserting my OS X install DVD and selecting it from the "Startup Disk" preference pane. Lo and behold, it rebooted from the DVD without asking for the password.

I have a PowerBook G4 17" 1.33 GHZ machine running OSX 10.5.5 that's booting either with a black screen or into open firmware. Any idea how I can reflash the firmware and if so, where I can download the file?

If rev C runs the GPU at a higher speed and hw otherwise is the same as rev B then why couldn't Apple release a firmware update to let rev BGPU rum faster as well?

After the update, my MacBook Pro is extermely sluggish. Prior to the update, I was zipping along like most happy MacBook Pro owners. After the update, I constantly see the dreaded beach ball when doing almost anything with the laptop, Safari pages take longer to load, etc.
It's almost as if the udpate had the opposite effect and actually throttled down my WD 500GB HDD performance to a large degree.
Like I said, prior to the update all was good. I've been searching to see if there is a way to revert back to the previous firmware to validate that the update caused the problem but I haven't been successfull in finding anything yet.

I currently have version 10.6.2 update for my macbook pro and after updating the EFI firmware update to 1.8 I get an annoying pop up every time I start the computer. I checked for any additional updates to see if it will go away, but I seem to have all the updates. Is there anything I should do to get rid of this pop up? Pop-up window reads: your computer's firmware is up to date with version 1.8 of the macbook pro EFI firmware update.

Installed the 2.8 firmware update on my late '08 macbook pro and after restarting it, it would just beep 3 times and not start up. I pulled my 8 gig kingston ram out, repositioned back and still the same issue. Slapping in the original 4 gigs of apple ram, it will start up and work fine though. Is there a fix to get the 8 gigs working again on the machine?

I just ran the latest firmware update for my 2011 mac book pro and after it installed it now won't start up, only getting to the gray screen before freezing there.
I've tried all the on line solutions I can find on Apple's site, but no luck.

MacBook Pro EFI Firmware Update 2.8 does not install. I was prompted several times to install and restart (MacBook Pro late 2008) and authorised it each time. In every case, the update was proposed again when Software Update checked. I have OS Lion latest version installed. What to do about this bug?

I did the latest firmware update few days ago and went through that series of boots. It's a shame on me that I didn't jog down the ROM revision info before the update. According to the this link:
[URL]
The FM Rev should be MBA31.0061.B01 after the update.
My MBA 13 is still read MBA31.0061.B00 after I thought I did the update. Does that mean the update didn't go through?

I have a uMBP 13' base model. I just received my Western Digital scorpio blue 500g hdd that is SATA 3.0. Should I install the new firmware update before I load anything onto the drive so i can utilize the 3.0Gbps instead of the 1.5Gbps? Should I install it at all? Will I notice a performance bump? I also received 4gb crucial ram, should i install the ram before installing the firmware update? I was wondering if anyone else noticed the screen slightly getting brighter and dimmer, almost in intervals, when it is not plugged into the power cord.

This update eliminates the noise made by the optical disk drive during system startup and wake from sleep on MacBook Pro computers. When installation is complete, please run Software Update again, and install SuperDrive Firmware Update 3.0. When I boot my system I can hear that sound like ejecting a disk out of the drive like always... Is that noise they refer?

I'm confused why it says "Your computer does not need this update"? It's a MBP4, 1 and has some startup noises and (always has had IIRC) problems with it making noises that don't seem right. I've checked Software Update and there is nothing there (I just ran it and updated a minute ago). I'm curious why it says this, is there a firmware update 1.7 that needs to be installed for the MBP?

I have a macbook 2.4 alu (Late 2008) and Installed linux as soon as I got it.(I just like the cases). Anyway I know that you need to use apple update in osx to update the firmware. I can't dual boot because my HD is MBR. I thought of 2 ways.
A. Install OSX onto a usb device (Cost 30-40 bucks for usb)
B. Take to apple store, Maybe they can do it.
I can't dual boot because my HD is MBR. I heard the new firmware updates stop a lot of issues.

I installed the EFI Firmware update 2.8 on my late 2008 MBP (running 10.5.8) and so far, it's seemed to solve the flicker/screen blacking out issue. I can no longer take screen shots any more without them being corrupted, and sometimes the Finder window gets scrambled and my wife needs to re-boot. I'm guessing a corrupted pref file somewhere. Anyone run into this recently and if so, is there a .plist file I can delete?

I recently installed the firmware update for my MacBook and when I restarted the keyboard and mouse were both unresponsive. Even my USB wireless mouse wouldn't work. I am probably going to take it into an Apple Store tomorrow. Oh, and also I booted Windows and my trackpad and keyboard are working fine (How I'm writing this now). Being the retard I am I guess I might have held the power button down. I tried taking the battery out and holding the power key for 10 secs - no use. I tried turning the MacBook on and holding down select+command+P+R (constant boot) - no use.
