We recieved unconfirmed reports Sunday that Apple is introducing a new version of OS X Intel to developers. This build, 8B1027, is based on Tiger 10.4.2, which brings it up to date with the latest commercial PowerPC versions.
There are several interesting things about this new build - first, some applications that were built on the initial version that shipped with the Developers Kits will not work in the new verison. However, all applications that are built using the new version (8B1027) will be unable to run on the earlier (WWDC) iteration. This incompatibility could be in place to deter pirated use of OSx86... or it could simply be that the operating system is still evolving.
Reports state that previous attempts to break the TPM support no longer work with this new seed. It would appear that Apple is learning from the hackers efforts and using that information to stop those efforts.
Several other fixes are noted with this build, such as completed programming frameworks, improved OpenGL support, and proper localization, as well as a few minor stability improvements.
All of this points to the fact that OSx86 is still a work in progress - nothing is complete. This opens a host of questions - why the sudden incompatibility between the two versions? Will the final version that is shipped with the Intel Macs be compatible with this new build? Is the motivation for this new build one of helping developers or detering hackers - or both?
