G'day my name is Luke and i'm from australia. I have an eMac and it is running OS X 4.10 and i am having a couple of issues. I am trying to install something and constantly i double click the program (not a dmg the other one) and installed jumps in the dock, the little black triangle appears and within a second it terminates and nothing happens. obviously there is something wrong with my installer program for OS X, could anyone be of assistance?
