Before we can get to play with Mac OS X 10.6, Snow Leopard, Apple plans to further polish their current big cat, the Leopard, by putting out Mac OS X 10.5.7. Reports on the web point out to the fact that version 10.5.7 of the Mac operating system has already been seeded to developers. The update weighs in at 440MB, it is labeled as Build 9J22, and aims to increase the stability of the Mac OS X. For people keeping track of these things, it must be said that Mac OS X 10.5.7 is the 7th major update in this operating system’s development process.

According to the testers involved with Mac OS X 10.5.7, Apple has insisted they focus on approximately 20 points of interest. The testers also claim that with this update Apple will make some 70 changes to the OS; nothing to spectacular, just some Mail and Address Book syncing issues and some enhancements to networking. Other tweaks and improvements will be made to performance, Safari not accepting cookies (certain types of cookies), graphics drivers, printing, screen sharing, MobilMe, AirPort, iCal, Time Machine and text services.

The ones to point the finger at Apple and the Mac OS X are the guys over at Apple Insider. “Apple this week is believed to have tapped its vast developer community to begin testing Mac OS X 10.5.7, a sizable maintenance and security update to the company's Leopard operating system with a particular focus on syncing improvements.,” says Kasper Jade.

Until the update arrives, there are other means that you could employ to keep yourself and your Mac OS X busy. You could get OnyX and tweak the operating system for free. Or you could read about Build 10A261 of the Mac OS X 10.6 and see what changes Apple has made with the Snow Leopard.
