Apple today seeded build 12D68 of OS X Mountain Lion 10.8.3 to developers, marking the tenth beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November 2012.

12d68
Build 12D68 comes roughly a week after build 12D65. Registered developers can download the update on Apple's Developer Page.

This post originally referred to Build 12D68 as the eleventh developer seed of OS X 10.8.3 when it was actually the tenth seed.

Do these betas include a new version of Safari that renders pages faster on rMBPs? (i.e. the "Webkit" version)

Admit it, you were too embarrassed to ask "Is Safari snappier?". :D

Sometimes it seems that Apple designed Mountain Lion just to increase their iPad and iPhone sales.

Usually it feels like you have no idea what you're talking about.
