Apple Releases iMac EFI Update 2.0 to Fix Sleep and Thunderbolt Issues




Apple has released an update for late 2012 iMac models that fixes issues related to sleep and Thunderbolt, as well as compatibility when using 5GHz Wi-Fi frequencies. The update is recommended for all "late 2012" iMacs.

iMac EFI Update 2.0 can be downloaded from Apple's support site or through the Mac App Store on affected iMacs.

About iMac EFI Update 2.0

This update is recommended for all iMac (late 2012) models. This update contains general performance fixes pertaining to sleep and Thunderbolt, and improves compatibility when using the 5GHz band in Wi-Fi.

Boot ROM or SMC Version Information: After Update is complete:

Build version: 010A.05
ROM version: IM131.88Z.010A.B05.1211151146
It's not clear if this is in addition to the Wi-Fi Update released earlier today, or if it includes that fix as well as a few more iMac-specific ones.

Update: Apple has released a similar MacBook Pro Retina EFI Update v1.1 for the 13-inch Retina MacBook Pro.

Both updates (the WiFi update *and* the EFI update) came through on my brand new 21" iMac. Must be distinct.

I wonder if this fixes the unmount on sleep w/ USB 3 hard drives. Otherwise what other sleep issues is the new iMac having? (Not home to try right now). Curious b/c the USB 3 issue was the only one I experienced. I wish Apple was more detailed in their update synopsis.

Good to see they are on top of things, just wondering how many updates will be waiting for new iMac users when we get them?

My 27" is a week-old and I have shut off sleep mode as it has a problem waking and requires my password and all open programs are quit. I guess our up will follow...

Will this help my 21.5" late 2012 iMac? I have issues waking from sleep whereby it wakes to a white screen only.
