So my Mac Mini, old, dusty PPC G4 with OS-X.4 finally got too slow to live. Opening a 250Mb file in Photoshop was taking 10 or more minutes - there was too much crap in the box.

So I bought a nice, new, dual Intel 2Ghz, CS3 and promptly loaded it up with fresh goodies...

After around a decade, most of my Photoshop filters no longer work.
OS-X.5.7 doesn't come with Stuffit support.

Basically, there's been a major overhaul to 64-bit architecture, and there's a bit of a lag in software support. Get the software, install it. Will it work? I don't know... is there a patch? Maybe... maybe an update? Maybe a PC version? Oh wait, Virtual PC won't work on an Intel Mac... so.. umm...

I'll just do it on my old computer.

At least the Open Source stuff stays current.
