@TIG, I did ask that at the start but overlooked the reply... @filippobasso said: About OSX install, I've a normal "File System Personality: Case-sensitive Journaled HFS+" OSX install, yes @Filippo, this is not a normal OSX install, and many apps will run into problems, not just SU... I believe OS X server and iOS are [Case-sensitive], but OS X became 'Case Preserving' in its standard releases... there are are few threads with reply from SketchUp staff discussing the known problems you will have... your second mac must have the 'standard' journalling if it works... john
