I’ve finished installing Jaguar and everything is running smoothly on my G4. I did a clean install and then selectively copied the contents of my old home folder to the newly created one. Applications launch very quickly – rarely more than 1-2 bounces. PhotoShop 7 launches in 7 bounces and finishes loading in about 10 seconds. I can sync my Visor with Palm desktop. Toast & iTunes recognize my Que FireWire CDRW. My VST Tri-Media drive works. My Kensington Optical Elite mouse & Kensington’s drivers work with no problems.A totally painless upgrade.
