10.8.3

Mountain Lion image

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.

    finally.
    ;)

  2. Patrick Fergus Says:

    Checking my downloaded 10.8.3 “Install OS X Mountain Lion” the SupportedModelProperties list lacks iMac13,1 and iMac13,2 (Late 2012 21.5″ and 27″ iMacs, respectively). The downloaded installer seems to not complain about being installed on an iMac13,1–is the support for these models tucked into SupportedBoardIds in the PlatformSupport.plist?

  3. Matt Zago Says:

    Echoing Patrick. The PlatformSupport.plist lacks values for the last rev of iMacs (13,1 13,2), Mac Mini (6,1 6,2), Retina Macbook Pro 13 (10,2), among others.

    I checked the build numbers of 10.8.3 on a new Retina 13″ vs a 2009 iMac and the builds numbers are the same (12D78). I can see the SupportedBoardId for my Retina Macbook Pro (Mac-AFD8A9D944EA4843).

    • Patrick Fergus Says:

      Where do you determine a particular computer’s board ID?

      • Matt Zago Says:

        Great question Patrick. I have no clue :(. Geekbeck is scraping it from somewhere, but I’m not sure where. I looked up motherboard ids from Geekbench results.

  4. Matt Zago Says:

    Funny enough I found how to identify board ids in a thread Patrick started on Macengerprise.

    ioreg -lp IOService | grep board-id

  5. GregN Says:

    There are more listed board-ids than models; I assumed that meant there wasn’t a 1-1 mapping: that some models had multiple board-ids.

    I’m not aware of an official resource mapping board-ids to models.

    It certainly would be nice to have, since it appears the SupportedBoardIds list is a better indicator of which models are supported.

  7. GregN Says:

    I don’t see MacMini6,* here either.

    Board-id for a MacMini6,2 here is Mac-F65AE981FFA204ED, which is in the SupportedBoardIds list.
