Apple is seeding the first developer release of Mac OS X 10.6.8, accounts say. The build is listed as 10K521, although details about its contents have yet to emerge. Mac OS X 10.6.7 was released in late March; at the time it made numerous fixes, dealing with components like graphics rendering and Back to My Mac. The v10.6.8 patch may be the last before the release of Mac OS X Lion.
