Apple Seeds Mac OS X 10.5.3 (9d19) to Developers
Apple waited a full week before seeding the latest version of Mac OS X 10.5.3 (9d19) to developers on Friday. The latest version of Mac OS X Leopard adds 31 bug fixes to the growing list of issues addressed in the upcoming release. Features that are specifically targeted for focused testing include AirPort, Back To My Mac, Spaces, Time Machine and many others.
Apple first seeded Mac OS 10.5.3 9d10 in late-March and has been issuing regular releases to developers.
Once complete, the final Mac OS X 10.5.3 update will become available as a free update to existing Mac OS X 10.5 (Leopard) users via Software Update. No target date is set, but testing for a new version can extend over several months.
