Apple Seeds OS X 10.5.7 Build 9J30 to Developers

by

In what has become an almost-weekly event, Apple has seeded a new version of Mac OS X 10.5.7, known as Build 9J30, to developers. World of Apple publishes the seed notes, which reveal that the lack of Safari 4 beta support is the only remaining issue Apple has chosen to highlight.

One week after the previous seed of Mac OS X 10.5.7 Apple has given developers another build this time in the form of 9J30. The rapid development of Mac OS X 10.5.7 suggests a public release before the end of March.

Developers testing build 9J30 have been asked to focus on new areas such as Flash Player, USB and Flash Drives, iCal and Widgets.

Apple seeded Build 9J22 on February 25th and Build 9J27 on March 7th. The declining list of known issues, brief time intervals between seeds, and decreasing intervals of build numbers between those seeds suggest that Apple is wrapping up development on OS X 10.5.7 and should see a release in the near future.
