Developers were supplied with a new Mac OS X 10.4.3 build 8F23 that includes 75 new bug fixes, bringing the total number of improvements the update will deliver to nearly 500. The update is currently 97.7MB big and may be released as soon as by the end of September.
Then there's also a new build of Mac OS X for the Intel platform. Mac OS X 10.4.2 build 8B1072 is a 2.7GB download that reinstalls the entire system and boosts the performance of the x86 Mac OS X to the speed of the PowerPC version.
The new build also addresses recent announcements from hackers who managed to install pirated copies of the x86 Mac OS X operating system on non-Macintosh computers.
Universal binaries built with Xcode 2.2 and the new copy of Mac OS X 10.4.2 for Intel will also fail to run on systems running the older version of the operating system.
