I guess Apple wants to screw you and FORCE you to upgrade to 10.2 server.

If anyone has gotten 10.1.5 to intall on the nwe DDR Powermacs, please tell me. Using retail CD of 10.1

Apple's official tech response is that it is unsupported and it will not work.

All of Apple's Hardware releases, every single one of them, have had minimum System version numbers.

In many cases, new versions of the OS were released specifically for the new hardware release.

The principle is that each new hardware revision requires specific support in the OS. If the current version of the OS doesn't have that support then clearly those features aren't going to work. Therefore you need the new release.

How could Apple predict in Mac OS X Server 10.1 the features that would be needed by the next rev. hardware?

What's confusing me most of all, though, is that if you have a DDR PowerMac, surely you have the 10.2 software you need to run it?

Not as obvious as it should be. I have an Xserve, ordered and shipped shortly before the announcement of 10.2, but delivered after that date. No 10.2 included, none in sight (though I sent in the required paperwork to the "up to date" program right away - and it's worth noting that there's a lot of technicality in this program, such that my perfectly valid requests to it have been denied for silly trivialities in the past until I finally managed to figure out just which piece of paper they required).

Apple does nothing serious to ensure that you get up to date software. I'm not surprised to hear that that can happen even if that up to date software is the only version that will run on the hardware you've bought.
