Upgraded my main system to Snow Leopard. Current casualties include:
Oxygen XML Editor
Otherwise, it seems that most of the apps are holding their own. The new Quicktime looks sweet and plays AVIs natively (so no more dubious third-party plugins — maybe).
Overall, seems to be a bit snappier — which is always welcome.
Tried upgrading a second system and got the domain manager error when trying to run the install from the DVD. Booted from the DVD (by restarting and holding down C until you hear the DVD grind). This update is still running…
I’ll update the post as new developments come to light.
