Apple Releases EFI Firmware Updates

I feel like my fans are way more active now. They were active before, but since the update I have noticed them a lot more. I never really felt that my computer was running hot but they are definitely more active. ANyone else notice this?

I have the exact same laptop as you, and no - I haven't noticed any difference in fan behavior. Given how loud they tend to be, I am pretty sure I'd notice if they were coming on more often or running harder.

Of course this is only since yesterday; but it sounds like you're seeing a dramatic, very obvious, change in behavior - so I'm sure I'd notice that.
 
Battery life fixed

The EFI update fixed the battery issue I've had. My Battery life declined to less than one hour after the previous battery update (I got the update while beta testing 10.5 at WWDC).
I know of at least one other person with the same problem caused by the battery update downloaded in 10.4.

I started up well over an hour ago on the battery tonight after applying the EFI update this afternoon.
The Battery meter went down to 65% right away so I assumed the EFI update didn't fix the battery issue. Since then, I've only lost 19% more in about an hour.
My battery is back. WooHoo!!

I stand corrected. Bad things happened when I shut down this evening to reboot into Windows. It killed the GUI of OS X but I was left with a command line just sitting there. Handed it to a friend who knows more about X then I do and said see! This is the crap I have to deal with because OS X hates me. (Seriously I never had this many problems in Windows.) He didn't believe me that I've had all these weird problems. :( Not sure what he did to reboot the system (Prob a kill command or something.) but after a reboot everything is working fine again. I've never had this problem until the update.

Ya I was never really conscious of them before, I mean if I had the comp flat on the bed where there was no air getting to the vents then sure they would come on, but now they seem more active. Sitting here now not doing much, I just finished an intense game of bejeweled (not full screen) and they are both running at 6000rpm according to iStat. I'll keep an eye on it, thanks for your reply
 
I updated my macbook it went smoothly but ever since my computer has a shocking delay on everything.:mad: is it possible to revert?

My 15-inch SR MBP didn't see the firmware update, so I manually downloaded it. The installer reported the update wasn't needed, so perhaps all SR MBPs don't need the update. Has any SR MBP owner been able to install the update?

I also had that; but that was probably because I downloaded 1.3 linked elsewhere and that was the EFI update of july 12 2007 and you do not need that one ;). These are the proper links and as you can see MBP owners require the 1.4 EFI update. These were all posted on sep 27th 2007:


iMac EFI Firmware Update 1.2

About MacBook Pro EFI Firmware Update 1.4
This update improves the performance and reliability of Intel Core 2 Duo processors and fixes issues with Boot Camp for MacBook Pro computers.

After the firmware is successfully applied to your computer, your BootROM Version will be one of the following:
MBP21.00A5.B07
MBP22.00A5.B07

[edit]
hmmm.. 1.4 also says 'this computer does not need this update' I have the following boot rom version:
Boot ROM Version: MBP31.0070.B02
It seems like EFI update 1.3 was the last update for SR MBP's and we don't need these updates...
[/edit]
 
Safari and Microsoft Word have each crashed once on my white iMac Core 2 Duo after the firmware update. Never had a crash with Word with old firmware (believe it or not). Safari crashed maybe once with old firmware. So far I'm not impressed.
 
cpu consumption after update

It may be an illusion, but it seems to me that the CPUs in
my Mac Pro consume slightly less power when idle
(as reporter by Hardware Monitor). Anyone else notice this?
 
Fixed it.

Problem solved, it was the GUID partion issue. I CCC'd my disk to an external, repartitioned, CCC'd it back, and it worked.

However, I got an error during the update where it wanted me to locate "System Events". I could not find an executable with that name, so I just hit cancel a few times and it still worked.

Checked, and my firmware is at the right revision now.

This link seems legit and has a newer update version (1.4) than what is on the other page (1.3) and what is supposedly on my MBP now. What is odd though is that update 1.4 has an earlier version number than the one listed for 1.3 (MBP21.00A5.B07 in 1.4 vs. MBP31.0070.B02 in 1.3). Both updates say that my MBP does not need them.


Edit: Discovered that the 1.4 update is for Pre-SantaRosa MBP's, the newest for SR MBP's is still 1.3. That means that my MBP already came with the newest and does not need any firmware update. Glad to clear this up.
 
I archived and installed back to 10.4.9 because I was having so many airport problems with 10.4.10, this EFI update requires 10.4.10, so have those airport issues been resolved with any other updates?
 
Huge improvements overall. I noticed booting into Tiger and/or Leopard is half the time, and shutting down/restarting doesn't hang in the slightest. My Mac Pro seems quieter as well :cool:.
 
i just thought about this... since this update deals with a hardware component, and requires 10.4.10... what happens if i reformat with my original disc (10.4.8)... and try to boot?

It only requires 10.4.10 to install the firmware update, not to use your machine.
It would be quite stupid if Apple didn't think of this right?
 
Has anyone actually noticed it say the EFI update is for late 2006 iMac models only? So the new Alu iMacs will not need this update!
 
After reading around, its because I upgraded my HDD. And its effectively, in the wrong format.

I'm hoping Apple will do a fix before I have to play around for a few hours =/
