Removing EFI Firmware update??

I just updated my firmware, which is now

EFI Firmware Update 1.2. won't install

I can't find exactly my problem but some threads are close. I keep getting software updates for EFI Firmware Update 1.2.
I shut down, then startup holding on-button until it flashes, release, buzz buzz, chime, then very briefly the apple logo and status bar, then gone, buzz buzz, chime and restart. After everything loads, there is the update window with install instructions, telling me to repeat if I see them, to no avail (tried several times over several weeks). My HD appears to be correctly partitioned, with this boot ROM: IM51.0090.B03 which would seem to indicate the update has not happened. I have unplugged all my peripherals (printer, zip drive) but not DSL modem.
any ideas?
thanks in advance

I would delete the firmware updater that is in your Utilities folder and check your account settings(System Preferences/Accounts/Login Items) to see if it has been added to your login items. If so then remove. Re-run your software update and see if the Firmware update shows up again. If so then download and try again. According to Apple your BootROM should be IM51.0090.B09 after the update.

After installing an SSD into my optical bay, I've found out I need EFI Firmware Update 2.2. I can only find 2.3 which is not supported on my Mac. What can I do?

After installing an SSD into my optical bay, I've found out I need EFI Firmware Update 2.2. I can only find 2.3 which is not supported on my Mac. What can I do?

You do not want EFI 2.2, it bricked many 2011 MacBook Pro machines.
EFI 2.3 is the fix. Software Update should install it if you need it, but it goes to the boot drive as that's where the hidden EFI resides.
Check out this link of machines and their EFI versions
https://support.apple.com/kb/HT1237
Also if your SSD should be in the hard drive bay as it makes a better boot/applicaitions drive, not a good storage drive as it wears out with repeated use and is not "scrubbable" like a regular hard drive
The hard drive should be in the optical bay and used as a storage drive, you have things all messed up inside your machine, Apple doesn't support or expect the optical drive to be used as such to begin with, then as a boot drive is just asking for trouble. So use the optical bay as storage and not as a boot bay.
Also you can't install OS X or Windows or use a Firmware restore disk because it only works from a internal optical drive, which you have removed.
https://support.apple.com/kb/HT2213
You need to learn all about cloning etc., as you have no other means to boot the machine.

Late 2011 MacBook Pro running Mountain Lion with app: "iMac EFI Firmware update"

I have an app on my MacBook Pro late 2011 model, by the name "iMac EFI Firmware update" that my computer says is useless... can I uninstall it using CleanMyMac without corrupting my OS Mountain Lion or simply dragging it to the garbage?

You can delete it. Just drag it to the Trash and this installer will be removed. As you have already installed this update, you don't need the installer anymore on the hard drive

Remove 'Micron Firmware Update' from BIOS

Hi, I have a 'Micron Firmware Update' listed in the bios boot options, how can I remove this from the list? I have a Ivy Bridge desktop PC with a 512gb MX100.I have previously updated the MX100 firmware.The 'Micron Firmware Update' remains as an option when all drives are disconnected. Thanks.

Yep, tried lots of stuff. SSD = CT512MX100SSD FW:MU01 on label, updated to MU02.
Motherboard = Gigabyte Sniper M3. The MX100 had caused some BSOD errors.
One that stopped windows from booting and caused a boot loop to 'Micron Firmware Update'. eg.
Boot
Micron Storage Executive.. Loading.. fdisk device has more than 2^32 sectors, cant use all of them.
Invalid firmware directory specified with -i option.
Reboot. Here is a list of what I tried to (A) get windows to boot and (B) remove 'Micron Firmware Update' from the bios.(not necessarily in order). Disconnected all drives from motherboard.
Format c: /FS:fat32 /v:system /q
bootrec /fixboot
bcdboot D:/windows /l en-us /s C: /f ALL
bcdedit /enum firmware
bcdedit /import
EasyBCD to check and read boot config on EFI System partition.
scandisk
SFC /scannow
Realise it would be quicker to reinstall Windows.
Diskpart clean
Reinstalled Windows in MBR mode (not UEFI mode).
Reset motherboard firmware to optimised defaults.
Loaded known good custom motherboard settings from backup.
Cleared CMOS with jumper on motherboard.
Removed motherboard battery overnight.
Flashed motherboard firmware with 'Q-Flash' embedded flash utility. Flash in DOS mode with efiflash.exe bios.bin /c
Its always the last thing you try that fixes the problem.

EFI firmware update & first crash

I updated yesterday my Mac pro with the Efi firmware update.
The 2 first trials to update didn't work and then I unplugged the 2 external firewire drives and my powerbook that was connected via a cross-over cabel and it finally worked.
I immediately was aware that the computer was running much faster (starting up, loading programs, etc) and that I had more free memory available.
The mac is running with only 1GB of ram (waiting for 2 GB more).
Today I experienced my first total crash. The screens went half dark and I was was asked to restart with the power button. At the time I only had mail and safari running. I was away for 10 min, so I might have put the mac to sleep (don't remember).
Have any of you out there experienced similar crashes?

Welcome to Apple Discussions!
I don't think installing firmware updates over the network works. Migrate the firmware update installer to the machine that has the need for the firmware and install it from there when nothing else is attached to it.
Also there is a firmware downgrade program which I suggest you install first before reinstalling the firmware over again:
http://www.apple.com/support/downloads/firmwarerestorationcd11.html
Make sure any third party PCI cards (except the graphics card which came with your computer), USB and Firewire devices are removed before installing the firmware update.

HT1237 Searching for an EFI Firmware update to enable Lion Internet Recovery on MacBook Pro (15-inch, Mid 2010)

Hi All,
My Mid-2010 Apple MacBook Pro 15-inch started having random kernel panics lately (more than 1 month of random kernel panics now), usually associated with request such as "open new tab in Safari" etc.
Since I installed 2x4GB RAM modules from Crucial when I bought my MBP (they are +- 2 years old now) and also exchanged my DVD-drive for an extra SSD that now runs the system (fully updated 10.7.4) I have a feeling that those kernel panics might be HW related.
I wanted to run Apple Hardware Test but found out that it is no longer supported on Lion. Since I don't have any optical drive to install AHT from (also I don't have the CDs with me atm), I found out that I can install an EFI Firmware update that enables internet-based (?) AHT.
At http://support.apple.com/kb/HT4904# , the link from MacBook Pro (15-inch, Mid 2010) links to MacBook Pro EFI Firmware Update 2.6 which is for Early 2010 models only and doesn't allow me to run the installation process. I'm looking for an EFI update to enable Apple Hardware Test on my Mid-2010 Apple MacBook Pro 15-inch.
Is there an update that can do this? Is there a wrong hyperlink on Apple page or am I searching for a wrong update?
Also, even though this should probably be in a separate topic, can anyone please point me to the right direction for a good Apple Kernel Panic how-to-read-those topic?
Thank you very much in advance.

Hey Cris from London,
I would try out the recommended steps in the following link:

Let us know if any of the steps within resolved the issue.

I downloaded and installed the: Mac mini EFI Firmware Update 1.6 on my mac mini running 10.8.1, was I correct in doing this ?

I downloaded and installed the: Mac mini EFI Firmware Update 1.6 on my mac mini running 10.8.1, was I correct in doing this ?
I didn't see this update come up in "Software Update"
If I was not meant to install this update, would it cause ANY damage at all to my mac ( this is my second as I dropped the first )
If I were to re-install ML would this fix any errors that this may have caused ?
The bottom of the page I link to says:
Boot ROM or SMC Version Information: MM51.0077.10
But when I click on "About this Mac" it says:
Boot ROM Version: MM51.0077.B10
SMC Version (system): 1.75f0
What does the additional "B" mean?
My mac mini is the Mid 2011 Model.
I am sorry if I am sounding super paranoid about this, but I don't want to have caused any permanent damage.

Hello,
It's somewhere between almost impossible & impossible to install the wrong EFI Update with all the checks it does!
Mac mini (Mid 2011) with Intel graphics
Macmini5,1
MM51.0077.B10 (EFI 1.6)
Mac mini (Mid 2011) with Radeon graphics
Macmini5,2
MM51.0077.B10 (EFI 1.6)
Mac mini Server (Mid 2011)
Macmini5,3
MM51.0077.B10 (EFI 1.6)
http://support.apple.com/kb/HT1237
Not sure what the B means.
If I were to re-install ML would this fix any errors that this may have caused ?
No, Firmware is unaffected by any OS change or re-install.

EFI Firmware update 1.4 was not successful, no progress bar

I have a MacBook Pro 2.16 Core 2 (MBP22.00A5.B02). Software update prompts me to download and update the Firmware 1.4 udpate. After following the instructuions, shutting down the computer, and restarting holding down the power button, I hear the beeps but nothing comes up but a blank (grey/white) screen. After several minutes (like 10) it restarts and the updater returns and shows not successful.
I tried to archived and reinstalled the OS with no luck
I have a 160GB Hitachi HD that came as ordered when I bought the computer new.
I have verified that the HD is GUID partition scheme
Only upgrade I have done is an extra 1GB stick of samsung original memory from OWC
I was hoping the firmware update might help cool down (and quiet down) this noisy "pro" laptop, but no luck. Please help someone.

Hi macinfrance!
I installed the EFI Firmware update successfully on my computer.
It seems to me that your list of nvram is lacking an entry telling your bootloader (boor.efi) exists on your normal harddrive partition.
I suggest the following (i am not quite sure if it will work):
1. Go to the system preferences and select the startdisk fane. Then, be sure to select your system harddrive.
2. Then restart your computer.
3. Make a restore CD in case something goes wrong (instructions at: http://www.apple.com/support/downloads/firmwarerestorationcd14.html )
4. Try the firmware update again.
When i type nvram i get the following contents:

MacBook Pro EFI Firmware Update 2.0 will not install.

Hi
The latest MacBook Pro EFI Firmware Update 2.0 will not install.
It runs and I restart my Mac but when I search for more updates it appears as a required update again.
Anyone know why this may be?

I had the same problem today. I called Apple support who transferred me to second level support and no resolution. I decided to try a combination of the items I have seen below.
I restarted my computer. I went to apple support download and downloaded the software EFI firmware update 2.0 by typing in search window. I made sure the power cord was pulled into the wall and the laptop had a FULL charge. I installed the update and the computer restarted.
I went to check the software update window after the update and restart completed and SUCCESSFUL.
I do not know why the Genius Bar or the second level support could not resolve my issues but, by me reading information here I hope at least this issue is resolved.
Thanks ALL.......... Happy Mac ing

MacBook Pro EFI Firmware Update 2.0

Hello,
I receive regular updates of the "MacBook Pro EFI Firmware Update 2.0" software. Each time I download, restart and let the update install. Each time it says update istalled succesfully... Yet each time I get the upgrade notice.
Worse now, iTunes says there is a software upgrade. But when I want to download it again I get the EFI upgrade announcement, but not the iTunes upgrade downloaded...
I've done a complete maintenance run, repair, rebuild, etc... but same results.
Thanks for any hint on what may be going wrong or how I can fix this.

I copied the version number from http://support.apple.com/kb/DL1331. That may be a misprint or typo on Apple's part. I'm posting a message asking about that in a special forum available only to level 4 or 5 users that sometimes gets replies from the folks that maintain those articles.
If I hear anything that confirms that, I will post back here, but for now I think it is safe to assume "B05" is correct.

Slow Booting time after installing MacBook Pro EFI Firmware Update 2.0 on 13 Inches Mac 2010 model

I'm experiencing a slow boot time after my computer installed a MacBook Pro EFI Firmware Update 2.0 itself on 13 Inches 2010 model, how to downgrade or fix it?
My computer is starting 2 times slower then it should be, why Apple done this to me?
Please help who really know somthing about Macs.

I have the same problem, especially when I open my laptop from sleep. It takes at least 2 minutes for the computer Internet connection to work.
Never had that problem prior to the last firmware update 2.7.
Is there a way to revert back to 2.6?

2006 Mac Pro & EFI Firmware Update 1.2

Wondering if anyone has any thoughts on this...
Just upgraded to Snow Leopard and was prompted to apply the EFI Firmware Update 1.2... so I did as requested... MP shuts down and I hold down the power button until I see the power light pulse rapidly... I see what looks like the start of an update (w/ the progress bar) but then the MP immediately reboots, returning to the Update application...
I should mention I tried holding down the power button through the tone as well, to no avail...
My Boot ROM Version: MP11.005C.B00
Thanks!

Some tests of Leopard vs Snow Leopard and 32-bit vs 64-bit
http://macperformanceguide.com/SnowLeopard-Performance.html
Snow Leopard is faster than Leopard regardless of 32/64-bit issue. Tests were of course done on a 2009 and using 4-drive stripe (to reduce impact of disk I/O from tests).
OpenCL synthetic tests (there aren't any apps that tap into this technology)
http://www.barefeats.com/opencl.html
Reasons why you may not want the slight advantage 64-bit mode offers (from PerformanceGuide):
*Sonnet Tempo E4P* Sonnet suggest that there will be some issues with 64-bit mode, but should be resolved quickly. Running in 32-bit mode should be fine. Be sure to update to driver version 2.1.9 (or later if there is one).

In addition, it looks to me like there never was an update for the Mac Mini 6,2 model.
