EFI Update and Exposé

Just wanted to know if anyone is having an issue with Exposé remembering the "Hide and Show" key that is set for Dashboard. Ever since the firmware update that fixed the dreaded RAW scenario it keeps forgetting they key that I select after I restart or wake from sleep. Trivial, I know, but a little annoying as I like to use the calculator widget often.

Now it's doing it at any point randomly, even when the MP hasn't been restarted. I'll be working along and then need to use the calculator, hit F13 and nada. I then check the preferences and nothing is selected. So set it back to F13 and go back to work. A couple hours later I try hitting F13 again and mind you without a reboot or shut down or sleeping it "forgets" the key selected again. Quite frustrating albeit a minor imposition compare to the RAW issue. Anyone have any suggestions?

Efi update and ambient light sensor issue

I just updated my early 2010 15" MacBook Pro with v2.7 EFI Firmware Upate. Now my screen ambient lighting is going nuts with changing the brightness all by itself, even with the AC power plugged in. The unit was working fine before this update. Are others having this issue? Is Apple aware of this and responding? I want to rebuild my laptop now but since it's a firmware update, it will be tough to undo this. I already tried the System Management Control reset and that did nothing. Thanks!

Thanks eww...
I had previously shut off the automatic adjustment since that was the only way to keep the constant dimming and brightening from happening. My main issue is that before this recent EFI upgrade, I never had to touch the automatic adjustment - now that's the only way to stop my problem. This is just a workaround and not a fix until Apple addresses it.

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.

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 today

After doing the latest EFI update today my WiFi will not work

After my latest EFI update today on my MacBook Air I have the countdown circle (like one you get when you shutdown) on for about 20 minutes. I have leave for work so I grabbed my iPad, now it's over an hour and the machine hasn't come back. I am afraid of turning off the computer since that potentially could screw up the machine. Anybody else has experience with this type of problem after EFI update and any advice?

Built-In iSight NOT RECOGNIZED after EFI Update 1.1

After updating to EFI 1.1 on my iMac 20 Inch (2,16Ghz) the built-in iSight-Cam is not
working anymore. It´s not showing up in the system profiler > USB Devices.
I bought the iMac last week, switched it on, the cam took a picture on the user account creation,
I applied the EFI-Update and OSX 10.4.8. After that the cam was gone.
I tried everything from resetting SMC, PRAM to reinstalling Combo-Update 10.4.8 ... NOTHING helped !
Any ideas or solutions ???
P.S.: Sorry for my crappy English, I´m writing from Germany !

Here´s a report from MacFixIt.com about this problem:
http://www.macfixit.com/article.php?story=20061211231332862
Built-in iSight not recognized Some users have reported loss of their built-in iSights after applying the iMac EFI Firmware Update 1.1. In some cases, this issue can be resolved by resetting the SMC (system management controller) using this process:
1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2. Unplug all cables from the computer, including the power cord and any display cables.
3. Wait at least 15 seconds.
4. Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5. Press the power button on the back to start up your computer.
Resetting PRAM can solve a variety of issues As mentioned in our coverage of recent EFI Firmware updates issued for other Macs, a number of potentially serious issues apparent after applying this EFI Firmware Update can be resolved by simply resetting PRAM/NVRAM via the following process:
Shut down your Mac, then start it back up while immediately holding the following keys: Command, Option, P and R. Hold the keys down until the computer restarts and you hear the startup sound for the third time.
This workaround is a good first course of action before exploring more complex fixes. It should also be attempted if your system cannot properly startup after applying the update.

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.

Because your MBP does not require it.

Macbook EFI firmware update 2.7 update and now my wifi doesn't work!

I did the EFI 2.7 update and now when I open the laptop from sleep on any wifi network it does work, and says im connected in wireless yet on safari im "not connected to the internet" after switching from one wifi network and then back to the original and waiting 30 seconds it finally works, i shouldnt have to fiddle and screw around with wifi on this computer when before the update it worked fine. I expect a fix from apple dang fast or if some one can tell me how to uninstall it, because it did nothing but ruin my computer experience. Very upset with apple right now.

I had the same problem, but was able to solve it by resetting the SMC control..
1) Power off the machine
2) HOLD OPTION + CONTROL + SHIFT + PRESS POWER BUTTON
3) Then release,
4) THEN POWER ON normally
This worked for me..

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)?

Same here actually. It worked for a bit though.

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.
