Apple Releases EFI Firmware Updates for Mac Mini, iMac, MacBook Air and Pro

by

Apple just released new firmware updates for the full range of Macs released in 2011, which apparently all fix the same issues.

This update improves the reliability of booting from the network, addresses an issue that can prevent HDCP authentication after a reboot, and resolves an issue with boot device selection when a USB storage device is hot-plugged.

The software updates are:

- Mac mini EFI Firmware Update 1.6 - Mac mini (Mid 2011)

- iMac EFI Firmware Update 1.9 - iMac (Early 2011)

- MacBook Air EFI Firmware Update 2.4 - MacBook Air (Mid 2011)

- MacBook Pro EFI Firmware Update 2.7 - MacBook Pro (Early 2011) and (Late 2011)

Um, that picture is under NDA. Unless you are not in the Dev program and then you just posted you have illegal software on your Mac. *wags finger* :cool:

EDIT: I should have added the *sarcasm* tag to my post. I really don't give a flying freak what anyone does. More power to you, I actually think ML is going to be okay, it just won't run on my older MacBook.


I bet you were a hall monitor. :D

I hope Mountain Lion breaks your Mac Mini.




Why such hostility?

In your life, have you ever done something illegal/against the rule?

He's just messing with beta software, he's not selling drugs or anything like that!

Does the MacBook Pro EFI update fix the SATA3/6g issue with the optical bay in 2011 15" and 17" MBP?

To my understanding, installing a data doubler with a sata3/6g SSD only gets sata2/3g speeds.

Did this fix it?


This latest EFI update does nothing to improve the usability of a 6Gb/s SATA 3.0 link connection in the 15/17" 2011 optical bays. If your system profiler reports 6Gb/s link in that bay and you plan to add a drive there - you must select a SATA 2.0 3Gb/s drive as the factory hardware and/or other particulars was not qualified to support 6Gb/s and it is NOT RELIABLE there with. Apple only uses that bay for optical drives that still link at 1.5Gb/s and would have done upgraders a service by using the 3Gb/s port link in that bay if not just properly supporting 6Gb/s in the first place there... but they have no reason to with respect to optical drive primary and only factory intended use.

We haven't given up and have a possible solution in the works we'll be able to test soon- but this isn't just some shielding. Also - it's far more likely that success will be found with the current gen Late 2011 version models vs. the original Feb/early 2011 models. The late 2011 starts off far far better right out of the gate - although not quite there vs. the earlier models that are, well, far far worse for the same.

We'll see. Been covering this on our blog for a long time with never ending testing across the board.
