New Mac user... can't figure out how to remove programs in OS 9.2 or OS 10.2. Please help. Also, I am trying to use the carbonized version of The Sims in 10.2 and it is stating that the current user doesn't have read or write priviledges... what does this mean? and finally, when installing a program like The Sims, which has carbonized and OS 9 versions...should I install on OS 9.2 or 10.2...does it matter?
