I tried the same patch on a stock Mac mini 256/80 1.42 GHz and it
works just fine so perhaps there be something about my Dual G4 1GHz
it does not like. I wonder if anyone else has seen this? Below is
the graphic card info:
The error you get means your machine does not support QT 7 visual
contexts, which Quartz Composer requires - do you have multiple video
cards? If not, then there's something wrong as your machine should
support them.
