Take for instance, MacPorts – a fantastic way of running some F/OSS on OS X.  Doesn’t work.  Experimental support is built in to nightlies… which I guess is getting there.  Little Snitch simply disappeared.  Programs with ktexts – kernel extensions – like SoundFlower and SteerMouse are also dead in the water.

Other more commonly used programs die as well.  MS Office can’t update.  The Aptna IDE is a non-starter.  In fact, you’ll find that a large percentage of your software works in a large percentage of the way you expect but… wait… what’s that?  Why does this particular function no longer work?

Granted, Snow Leopard won’t be out until September probably, so there’s plenty of time for programmers to get their code up to date.  As one of those programmers, I can tell you that it’s going to be a bit of a battle.  I’m running into major roadblocks with Twistori Desktop and the ScreenSaver.framework package that differs a lot from Leopard->Snow Leopard.

In fact, none of your screensavers on Leopard will run in Snow Leopard.  Just an FYI.

Anyway, that’s enough of a rant.  I keep going back and forth between downgrading or not.  I need to start developing heavily in Snow Leopard to make sure that Multiplex and Twistori Desktop are ready.  However, I also need to push solid releases sooner than Snow Leopard will be released to our Leopard install base.

Hmm… what to do…
