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.

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.
