Apple Releases Firmware and OS X 10.8.5 Updates for Late-2013 iMacs

[MacRumors]

Apple has a released a new firmware update -- iMac SMC Firmware Update 1.1 -- for the new iMacs released in September.

Simultaneously, Apple also released a supplemental update for OS X 10.8.5.

iMac SMC Firmware Update 1.1

This update is recommended for iMac (late 2013) with flash-only storage. This update improves the Power Nap feature in Mavericks on your flash based iMac by allowing it to perform silently, without spinning up the fan.

Power Nap periodically updates apps, such as Mail, Contacts, and Calendar, and will download software updates while your iMac is sleeping.

iMac 10.8.5 Supplemental Update 1.0

The iMac OS X v10.8.5 Supplemental Update 1.0 is recommended for iMacs (Late 2013) using NVIDIA GeForce GT 750M graphics and running OS X Mountain Lion v10.8.5.

This update:

- Fixes an issue that may cause external drives to be ejected after the computer goes to sleep
- Fixes an issue that may prevent certain USB Bluetooth adapters from working

They aren't the first updates for the new iMacs -- when they were first released, Apple released an EFI update to address Boot Camp installation issues.

iMac SMC Firmware Update 1.1 and iMac 10.8.5 Supplemental Update 1.0 are available for download through Apple's support website or through the Mac App Store's software update mechanism.

Way to go Apple for producing updates to an old OS even when they made a new OS.

On a side note, this new push notification thing is great! First comment

My 2013 27" with the Fusion Drive applied the firmware update, despite the description saying "recommended for iMac with flash-only storage." Not sure if it'll affect mine or not, but either way, good deal.

It'd be nice if they'd push a fix for mavericks that makes the scrollviews not jitter.

Love the push notifications. Looking forward to more sites using it.

I applied the update to my late 2013 27" iMac. Now the external hard drives keep unmounting randomly. Turned off sleep, turned off nap. Hard drives unmount while awake and using computer. Pissing me off.

Well I updated this and didnt notice a single difference. Oh well. At least I feel like something was refreshed and refined.

I don't have a imac but was able to get the build number by opening the file SystemVersion.plist in the installer and it said it is 12F2029
