OS X Mavericks 10.9.3 (Build 13D28) Seeded

Apple seeded a fourth test build of OS X 10.9.3 (13D28) to registered Mac developers, available through the 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

Everyone else who is interested in testing OS X 10.9.3 (13D28) 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"

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.

Changes

This build is said to fix previously introduced graphics issues for people stuck on a white/gray screen. Here it only worked when I plugged in a VGA cable. VGA output was garbled nonetheless, but at least DP/DVI/HDMI worked with 13D21. Others had to unplug their cable and plug it back in after a successful boot. Yeah. Crazy stuff.

Interesting. I found a new board-id (Mac-C9CF552659EA9913) for a new/unknown Mac model.

The rest is TBD (no time yet).
