There’s two big reasons Mac users are waiting for the new update to ship: Number one, it is required in order to use a Magic Mouse; Number two: it reportedly patches the dreaded Guest account data-munching bug that has caused such distress. Apple conceded the existence of that bug earlier last week, after multiple reports complained of its existence. As reported by OS X Brazil, (and reported earlier by MacRumors) developer build, Mac OS X 10.6.2 Build 10C531 fixes the one outstanding issue related to Image Capture mentioned in the previous build (10C527f), as well as half a dozen other problems related to ColorSync, Dock crashes, GraphicsDrivers, and QuartzCore. Build 10C531 lists no known issues, although this may not be a clue that the development is wrapping up. The site also published the seed notes for the release, elements of which we have republished here: “Mac OS X 10.6.2 build 10C531 Seed Note Known Issues – None Focus Areas (Changes in 10C531): ColorSync – Fix black point compensation images when selecting a printer profile Dock – Resolve a crash in Dock GraphicsDrivers – Resolve a Sims 3 video corruption – Resolve a kernel panic in GraphicsDrivers – Resolve an iTunes hang with video corruption QuartzCore – Resolve a Ken Burns effects issues on iMovie – Resolves an issue with Image Capture scanning.
