EFI Update 1.3 and VRAM

Hello everybody! When I was installing EFI Update 1.3 The instructions said that press on/off power bottom, saw the light blinking. But the instructions didn't say that you can hear a very strong noise.... Is it normal?? Now, EFI Update program say that all it's OK, but when I wanna restart VRAM (Commandoption+PR) the second sound start too slowly... So, please, what can I do???
Thank you so much and regards

Same here actually. It worked for a bit though.

EFI update 1.8 and the wakeup noise is back

I have applied EFI update 1.8 but replaced my drive (the drive was bad) a couple of months ago.
The drive is making again the wakeup noise! (EFI 1.8 was supposed to fix that)
I am not certain that the return of the noise is related to the drive change but it looks so.
Any way to remove the noise. Does the superdrive need a firmware update? If yes how do you do it (as the EFI change is not accepted anymore)?

EFI Update Needed?

I just replaced the power cord for my MacBook4,1, and the guy at the genius bar said that I needed to install an EFI update. I found a page at apple/support that lists out EFI updated by machine, and there's none listed for mine. I tried installing other versions but kept getting the pop-up saying my machined didn't need them. This is probably a stupid question, but am I OK without the update? The guy at the genius bar said my computer would only accept the new cord a limited number of times without the update.

The best idea would proably use screen sharing from another mac and just run the software update from there.
You will be able to see what is going on durring the process. You will then need to reboot and should be good to go.

Efi update 2.5 does not apply

I cannot apply the MacBook Pro EFI update 2.5, and now the SMC update. The updater tells me they are available, but after restarting, I see they have not been applied, and the updater agrees, and tells me they are still available.
When the computer restarts, I'm supposed to see progress bar duting the update? If so, that never comes up.

The problem appears in /var/log/install.log. Search for 'EFI' in this file. You will find the errors. In my case the EFI partition (?) was missing, the only solution was to do a complete clean reinstall, removing every (bootcamp) partition and start all over again from scratch. Things go faster when using a spare harddisk, swap it with your default one, install Lion 10.7.3 and update the EFI. Then swap back your SDD or default HDD.
Edit: and as always: make sure you have a current Time Machine backup. Also don't forget to backup your Bootcamp partitions seperately if installed.

Interruppting EFI Update

What happens when you interrupt the EFI update?
I was in the middle of running my EFI update. Now I can't seem to get my Mac running. I tried all the troubleshooting tips that was in the manual. I also refered to the update instructions again to try and restart the update. Now my LED light blinks from dim to bright.
Is there something that I can do or would have to return my laptop?

Welcome to Apple Discussions, Shugah Shane.
EFI updates should not be interrupted. But you know that now
Did you read this support topic also? You may be able to create a restore disk w/o bringing your Mac in for repair.

Performance reduced under Bootcamp after EFI update on Macbook Pro Retina

after i upgraded EFI on my retina macbook pro the proformence reduced to unusable. under heavy load under bootcamp windows7. the cpu clock drops and as well as cpu clock. this is the screen shot of gpu clock monitoring from windows u can see the gpu clock is running at 270Mhz at most of the time and trying to be back to 725Mhz(yea, not 900Mhz!) when im running a graphic benchmark at same time cpu will run about 1.1Ghz as well. i noticed that it will run 10-20sec normally then CPU and GPU clock will start dropping. It's almost like speedstep is programmed backwards. My CPU is constantly running at 3.1-3.2GHz, and then as soon as a game loads, it drops to 1.2GHz. I've lost track of how many times I reset the SMC reseting SMC PRAM, reinstalling windows using Bootcamp or even erease the entire drive and start over from network recovery MacOS did not solve this problem. so all the recent games like COD MW3, Starcraft II, BF3,or D3 will only run about about 10 fps as i was playing them with no ploblem before the EFI update.
this is killing me! please help.
im in NY, in this season i dont think is the overheating problem. when i check the temperature, it stays about 80C (fans will run about 4k rpm). but some time heavy loaded Mac OS cpu is about 90 degree but only with 3k rpm fan kicked in.
i did search online, seems that some other people have the same problem with rMBP or MBA 2012.
anyone knows if i take my macbook pro to the store, will those people work at genuines bar help me with this "windows" problem?
thanks!

Hey Shadowyani, please take a time and fill a bug report at http://developer.apple.com/bugreporter/ . The machine is useless for me as it is now because I develop and use very GPU/CPU demanding scientific applications, after the update my realtime applications are completely useless as they drop from something like 25fps to 9 fps even on Mac OS X (no SMC reset fixed the issue). In bootcamp the situation is worse, my software runs at 4 fps and gaming turns to be impossible to play as well.
Please let Apple know about the problem, fill a bug report, even if SMC reset once in a while fixed the issue for you (this is not a common behaviour and must be fixed). We paid the price for cutting edge technology.
Apple shall not do a downgrade of the system after few weeks, remember that most of reviews and benchmarks were done BEFORE the EFI Update, so people are being fooled by Apple in this sense.

EFI Update Causes Time Machine Problems

After the EFI update today (10/12) Time Machine will no longer mount its disk image on an external network drive via AFP wireless connection. The external drive is presented through Ubuntu 8.10 with Netatalk 2.03. Anyone else having this problem yet, or better yet have a solution?

Fixed it! Mounting it in Disk Utility and repairing the file system worked. It should be noted however that I can't confirm the update was the cause of of this problem but, its some kawinky-**** huh?

EFI Update 2.9 other issue

After EFI update 2.9 Wifi no longer automatically connects to remembered networks on wake. I was having the highly delayed wake issue on occasion that this update was said to fix. Now even time I open the lid (100% of the time so far) i must manually connect to my home network it will not automatically connect. any ideas?

I had this same issue. On an uneducated whim, I totally Shut Down my Computer, waited about 5 minutes, then pressed the Power Button and
it has been 2 days and No More Problem with the WiFi issue.
I might be speaking too soon, but, so far in the past 2 days it seems to connect!
You can also try to delete the Network you use in System Preferences Network Advanced and then Add it back then go up to the WiFi Icon and turn it off, Then turn it back on and check Remember this Network. Someone suggested that, but so far just Turning Off My Air and waiting 5 minutes, the turn it back on solved my problem.

EFI Update v2.6 breaks Windows dual boot

The EFI Update MBA51.00EF.B02 has broken WIndows on my MacBook Air 2012
Bootcamp Dual boot using OSX Lion & WIndows 7 was working fine prior to the EFI update.
Since then, the WIndows initial boot screen displays, but as soon as the GUI starts there is a blank notebook screen.
Using an external monitor connected via Thunderbolt > VGA adapter, the Windows GUI Logon & desktop shows on the external monitor, but Control Panel display manager cannot see the MBA own lcd screen as a display option.
This makes it unusable as a portable WIndows M/C, as instead of fixing WIndows it has broken it.
Can I regress ?
Is there a fix to this issue ?
Please Help

@vintherine: Everything you mentioned in the 1st post is correct. In your case the correct commands should be:
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --recheck
grub-mkconfig -o /boot/grub/grub.cfg
Thanks. I've tried that, get now a single line with Windows, which does not work
EDIT: Are you able to boot Windows independent of GRUB, ie. directly from the firmware boot menu?
I've tried F12 key, found a menu, started on the HD, found a new menu corresponding with the EFI directories (arch_grub, Microsoft....). Microsoft entry sent me on... grub menu
EDIT: Can you try (note the extra line : "set gfxpayload=keep")
It's time for diner (i'm in France). I'll see this in the next hour.
Many thanks
Seems like the actual Windows bootmgfw.efi was overwritten by grubx64.efi or something else. In the boot menu Windows's entry (created by Windows installer) is usually titled "Windows Boot Manager".
EDIT:
Try this. Copy the files from Windows's C:\Windows\Boot\EFI to <EFISYS>/EFI/Microsoft/Boot/ . Overwrite any exisitng files, and make sure <EFISYS>/EFI/Microsoft/Boot/BCD file exists. That is the Windows equivalent of grub.cfg (although BCD cannot be read easily since it is not a text file). Try your menuentry again.

IMac EFI update problems

My Mid 2011 iMac 27" i7 will no longer start after the latest EFI update.
I decided to perform some system updated on my iMac and after installing 10.7.3, I rechecked and it found the EFI update and one other update. They were both pretty small (the largest was 3.6MB), so I decided to proceed prior to getting back to business with my system.
After downloading the updates (took about 5 seconds), the machine proceeded to restart. There was a loud beep prior to the system restart chime after which it went to the grey-white apple startup screen with the spinning wheel.
And it stayed there.
After 35 minutes with no discernable progress, I decided something must be wrong. This system normally takes about 30 seconds to boot from a cold state (it's running on an OWC SSD) or maybe a minute after updates. So I held the power button to reboot. But it keeps going to the same state. I tried to reboot to a different internal drive holding the option key, but the same thing happens.
System Specs:
iMac 27" i7 3.4 Ghz (mid 2011) 12G Ram
Internal 1TB Apple HD
Internal OWC SSD 240G (main startup drive)
Here are my questions:
1. How do I recover from this?
2. Is anyone else running into this problem?
3. How long do the EFI updates normally take?
4. Shouldn't there be some sort of "progress bar" to indicate something is going on during this process? Or, if not, then perhaps a "WARNING!! This process will take up to two hours, during which you will receive no discernable feedback. Do not interrupt the process until more than 24 hours have passed with the spinning ball."
Thanks for your help.

P.S. I think this is my last iMac EFI update. After my last iMac received an EFI update (2009 model 24" iMac), it became ultra-flakey and started corrupting HD's. It never worked the same after that. This machine was working PERFECTLY before the update.

I don't have the link to that thread, but here is how to do it:
To reset the SMC:
Shut down your system.
Unplug all the accessories from the system
Unplug the power cord from the iMac and leave it unplugged for at least 15 seconds.
Reconnect the power cord. Wait another fifteen seconds and restart the computer.
To Reset the PRAM:
On startup, hold down these keys at the same time (must start before the grey screen comes up): command option p r
Hope that helps.

HT1237 EFI Update 2.8 doesn't install

Where can I see if the EFI update 2.8 for my MBP 2008 works properly? after I manualy installed the update 2.8 there is stil version 1.8 visible and the display stil flickering.

This update was designed for the 15" MBP from 2008. If so, you might consider visiting your local Apple Store, where they can investigate the issue.

2011 EFI Update problem

I just ran the latest EFI Update on a (new) 3week old MBP. The MBP SW update ran fine... then It indicated to run EFI Update...
THe update appeared to run , with gray screen and progress bar. It ran to completion restarted.
AND all I get is a grey screen (no Apple icon).
I cannot access this MBP any ideas?

Boom
You should, if you can get your machine see what version your ROM BIOS is MBP81.0047.B0E. If it is that you don't need the 2.1 update, unless of course software update pulled it down. I just brought my MBP home last night, and did software update and my MBP does not need the 2.1 update. Also my MBP came wiht OSX 10.6.7 already installed as oppose to earlier MBP wiht 10..6.6

Can EFI update be rolled back?

I installed the EFI update and now my e-sata drive I use for Time Machine won't mount. Worked perfectly before the update.
Is there any way to roll it back to the previous version?

No. It would be nice if Apple were to offer that option,
but currently they don't.

EFI Update Lost The Speakers?

I'm on a brand new iMac 24". I ran System Update and now all the software is up to date. Part of that, apparently, was an EFI updater, which I also ran. After the EFI updater, the iMac no longer "sees" any internal speakers.
Here's a screen shot: http://i14.tinypic.com/6hgi0dc.png
Any ideas?
Intel iMac 2.16GHz Mac OS X (10.4.10)

Open GarageBand and see what happens.
Also after all these updates did you go to Apps/Utilities/Disk Utility/First Aid and Repair Disk Permissions on your boot volume?
