New Mac OS X 10.5 (9A283) Leopard Seed

Apple has seeded a new version of Mac OS X 10.5 (Leopard) to developers. Apple first previewed and seeded Mac OS X 10.5 (Leopard) at the Worldwide Developer's Conference (WWDC) in August. This same build was later seeded to Apple Developer Connection developers, with one minor online update in September bringing it to build 9A241e.

Today's update (build 9A283) is only available for ADC developers (Select and Premier) and is intended as a fresh-install (rather than updating the WWDC build of Leopard).

Changes from the WWDC seed include:

- new Parental Controls preference pane for content filtering, apps, and curfews
- Significant user interface changes to iCal
- 3D audio cues to indicate locations of items on the screen in the VoiceOver screen reader
- Basic editing in Preview

There are still several known issues documented.

Mac OS X 10.5 (Leopard) is expected to be released in Spring of 2007.
