Apple Releases EFI Firmware Updates

Peace said:
EFI doesn't "emulate" BIOS.EFI has a BIOS module in it.There is a difference.

EFI is not a "successor" to BIOS.

EFI is Extensible Firmware Interface and can contain 20 different type of "modules" including BIOS.Basic Input/Output System.

The BIOS is on a chip.

The EFI module is also on a chip.

You really have no idea what you are talking about, do you? You are just regurgitating semi-understood stuff you once heard.

Both BIOS and EFI are firmware (software stored in hardware) which are executed upon system startup and do things like check to make sure the computer is OK, initialize the basic hardware needed to load the OS, actually load the OS, and then hand control over to it.

BIOS is the old, de-facto standard still used to this day on Wintel machines. Macs used to use a different firmware called Open Firmware on PPC machines.

Intel Macs use Intel's new spec for firmware called EFI. This spec was created by Intel to replace BIOS on Wintel machines and fixes many little irksome problems with the older BIOS. EFI was introduced before Intel Macs were even a twinkle in Jobs' eye.

Sadly no PC manufacturer used it till Apple came along with their Intel machines.

This is all low-level stuff and has nothing to do with the average user.
 
this update does not apply to SR mbps 15 inch? I just tried it and it said, this mbp does not need this patch
 
Just updated my Mac Pro. I followed the steps -- and it didn't work. After holding down the power button, the progress bar did come up on my screen. It finished, but the system did not reboot. It just sat there with nothing on the screen. I let it sit for about 15 minutes, then when I was sure the hard drives were silent I gulped and pressed the power button. It rebooted and came up no problem.

I'll start breathing again now.
 
I tried to update the EFI on my 15" 2.3GHz Macbook pro. When I press shutdown it comes back saying "An unexpected error occurred (0). Your fimware can not be updated." Any idea how I can get it to install?

Did the update come from Software Update or did you download it manually?

I know you weren't quoting me, but mine came with the software update. Same computer specs as him though.

i get this error, but i'm using a white macbook, not a pro .. also downloaded it from software update
 
As a bit more info, my current Boot ROM is: MBP22.00A5.B01

It looks like mine is supposed to be upgraded to MBP22.00A5.B07

I am going to try repairing permissions. Maybe that's causing it? Update: Didn't work (of course :p)
 
I tried to install the update on my SR MBP and it said I didn't need it. I went to system profiler and my bootrom was not up to date, what gives?
 
I've just noticed a real change on my C2D MacBook!
(Don't know if it has been already posted, but...)

Before the EFI update:
If I had a USB mouse or flash drive connected to the MB and put it to sleep closing the lid, it always wake up whenever I plugged off the mouse or flash drive.
After the EFI update:
I plug off the USB mouse and my MB keeps asleep with its lid closed.

Good thing! now it's much better.
 
MacBook C2D 2.0Ghz: Updated EFI

iMac C2D 2.16Ghz: No EFI update available

iMac C2E 2.8Ghz: No EFI update available
:(

When I pressed the power button for a few seconds on my macbook, I heard a very loud beep from its speakers.

Anyway, I'm waiting for someone to say that Safari seems snappier.:D
 
EFI Update Screen Captures

Whew!

I just updated my 17" MBP (not SR)...
