Mac OS X 10.6.2 beta fixes Guest account data-munching bug

Apple has seeded developers with a new build of Mac OS X 10.6.2, the next major update for Snow Leopard, in which it has addressed the nasty Guest account data-destroying bug, reports of which have been in a flurry in recent weeks.

Apple conceded the existence of this bug earlier this week, after multiple reports complained of its existence following our earlier report the prior week.

The seed is said to contain just one issue and to carry two sets of release notes, suggesting the code’s on the fast-track to release, once successful testing is completed.

The software also promised reliability improvements across Apple apps, including iWork, iLife, Aperture, Final Cut Studio, MobileMe, iDisk, and Safari.

The only known Issues in the release is that Image Capture returns a black image when scanning in black-&-white and Image Correction is in manual. Read on for full notes…
