Apple Prepping OS X 10.5.7 Update

Apple yesterday seeded Mac OS X 10.5.7, the next maintenance release for Leopard, to developers. Apple is requesting that developers focus their testing on over twenty areas of the new seed, which is termed Build 9J22.

Developers familiar with the new build report that Apple has made nearly 70 changes in the update, with many of them focused on syncing and networking improvements. A number of preferences and widgets have seen tweaks to address performance issues, and Apple has also addressed several issues related to RAW image handling. Also of note, Apple has addressed an issue with Safari not accepting certain types of cookies.

Apple has also informed developers that the new Safari 4 public beta will not install on the current 10.5.7 build. The last update to Leopard, OS X 10.5.6, was released in December.
