Today Apple finally released OS X 10.8.3.
This release has been awaited by many Mac admins as the hope was that this version would support all Macs capable of running Mountain Lion. Prior to this release, the Late 2012 Macs (iMacs, 13″ Retina MacBookPros and Mac minis) required a different build of 10.8.2 than did other Macs.
This required having multiple restore images or OS installer pkgs and possibly multiple NetBoot disks to support all the Macs in your organization.
The hope (and assumption) was that 10.8.3 would unify the Mountain Lion builds, and that all recent machines would be able to use the new version.
How, though, to be sure? One way is to look at what Apple says. Mount the InstallESD.dmg disk image inside the 10.8.3 Install OS X Mountain Lion.app and take a look at /System/Library/CoreServices/PlatformSupport.plist.
One of the keys in this plist looks like this:
<key>SupportedModelProperties</key> <array> <string>MacBookPro4,1</string> <string>Macmini5,3</string> <string>Macmini5,2</string> <string>Macmini5,1</string> <string>MacBookPro5,1</string> <string>MacPro4,1</string> <string>MacBookPro5,2</string> <string>MacBookPro5,5</string> <string>MacBookPro5,4</string> <string>Macmini4,1</string> <string>iMac11,1</string> <string>iMac11,2</string> <string>iMac11,3</string> <string>MacBook7,1</string> <string>MacBookPro3,1</string> <string>MacPro5,1</string> <string>iMac9,1</string> <string>Macmini3,1</string> <string>MacBookPro6,1</string> <string>iMac12,2</string> <string>iMac12,1</string> <string>MacBook5,1</string> <string>MacBook5,2</string> <string>iMac10,1</string> <string>MacBookPro7,1</string> <string>MacBookAir4,1</string> <string>MacBookPro5,3</string> <string>MacBookPro6,2</string> <string>iMac8,1</string> <string>MacBookAir3,1</string> <string>MacBookAir3,2</string> <string>Xserve3,1</string> <string>MacBookAir2,1</string> <string>MacBookPro8,1</string> <string>MacBookPro8,2</string> <string>MacBookPro8,3</string> <string>iMac7,1</string> <string>MacBook6,1</string> <string>MacPro3,1</string> <string>MacBookAir4,2</string> </array>
If your Macs are in this list, they should be supported by 10.8.3.
UPDATE: There are some Macs NOT in this list that are also supported by 10.8.3 — those are the “Late 2012″ Macs. See the follow-up post.


Today Adobe released yet another Flash update. If you need to deploy it in an enterprise environment and head to 
I’m speaking at MacTech Conference 2012, held October 17-19th in Los Angeles. The speakers and sessions have been posted here: 
MacTech Conference 2012
October 1, 2012I’ll be presenting again this year. More exciting, on Wednesday evening, October 17th, MacTech Conference attendees will be guests at a special event at Walt Disney Animation Studios. Not only will they get a behind-the-scenes look at the Animation Studios and talk with Disney technologists and artists, but also have a rare look at how Walt Disney Animation Studios uses advanced technology to create their animated films.
I look forward to seeing you there!
