After a long telephone call with the Apple support I have just found out that:
1) My brand new Power Mac G5 does not run Panther because of the new Firmware.
2) XCode 1.5 does not run under Tiger. 3) XCode 2.0 does not run under Panther.
Despite the fact that it is simply incredible that a new Hardware does not run an OS that only tow weeks behind the latest version in my special environment it seems as if (at least for the moment) we would not be able to build our application under XCode 2.0 because of problems in XCode 2.0 and at the same time I'm neither able to run XCode 1.5 under Tiger nor to install Panther on my new G5.
Is this really possible or am I just to stupid to understand the big picture Apple has in mind? In my case I now have to return my new G5 and try to buy an older G5 that still run's Panther.
Any help or comment are welcome
