OS X Mavericks 10.9.3 (Build 13D43) Seeded

Apple seeded a sixth test build of OS X 10.9.3 (13D43) to registered Mac developers, available through their Software Update mechanism in the Mac App Store, as well as through the Mac Dev Center.

Focus Areas

– Graphics Drivers
– Audio
– Safari
– Contacts and Calendar sync over USB in iTunes
– Mail

Everyone else who is interested in testing OS X 10.9.3 (13D43) without being a registered Mac software developer can change their App Store URL by entering the following terminal command (all on one line):

sudo /usr/sbin/softwareupdate –set-catalog https://swscan.apple.com/content/catalogs/others/index-10.9seed-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

Tip: You can also open the App Store from a terminal window with:

open macappstore://showUpdatesPage

Edit

You can restore to the original Apple catalog by resetting the override URL with help of the following terminal command:

sudo /usr/sbin/softwareupdate --clear-catalog

After that the CatalogURL property will be removed from /Library/Preferences/com.apple.SoftwareUpdate.plist and when everything went fine, you’ll see this text: softwareupdate: Changed catalog to Apple production
Back to the factory original (production) catalog.

Warning

This update won’t show up under Updates in the App Store when you are still using the 10.9.2 Golden Master (build 13A598) or already have OS X 10.9.3 (Build 13D28) installed. There’s an additional check for build 13C64, which was first released to Apple employees and a day later to the public.

Changes

In this build AGDC (Apple Graphics Device Policy) has improved, and as a result my DVI monitor (with my IGPU only setup) works without any modifications to AppleIntelFramebuffer.kext whatsoever, though I had to change:

/S*/L*/E*/AppleGraphicsControl.kext/C*/P*/AppleGraphicsDevicePolicy.kext/C*/Info.plist

<key>ConfigMap</key>
<dict>
	<key>Mac-F60DEB81FF30ACF6</key>
	<string>none</string>
</dict>

What I did was that I changed the factory “Config1” to “none” (Config1 unloads GFX1) like all other models under ConfigMap (iMac14,1/MacBookPro11,1/iMac14,2/MacBookAir6,1/MacBookPro9,1/iMac14,3/MacBookAir6,2/Mac-81E3E92DD6088272/MacBookPro10,1/MacPro4,1/MacPro5,1/MacPro3,1/MacPro6,1/iMac13,3) Without this mod only the DisplayPort monitor connector worked.

Did you catch the Mac-81E3E92DD6088272 in that list? That is a new board-id (for OS X 10.9.3, not this specific DP) and thus Apple could be planning to release a new Mac with OS X 10.9.3 installed on it. What I can tell you is that this specific board-id is not another Mac Pro, and the most likely candidate is a brand new Mac mini. Or is that just my imagination. Hoping for a new Mac mini?

Edit: We know now that this board-id (Mac-81E3E92DD6088272) is for the 21-inch mid-2014 iMac (iMac14,4).

Also. A quick look at /S*/L*/E*/IOPlatformPluginFamily.kext/C*/P*/X86PlatformPlugin.kext/C*/Resources revealed that all plist are unchanged.

Well. This has to be it for now folks as I need to go – sanding a 30 meter wall and paint the darn thing for a second time. Have fun!

Update:
I forgot to mention that I found a new GUID. One used to store/retrieve the DisplayBackgroundColor (options/):

“FA4CE28D-B62F-4C99-9CC3-6815686E30F9:DisplayBackgroundColor”

There might be more. Will keep searching for new stuff.

Update 2:
Worked around a stupid wordpress.com code block issue.
