I have a PowerBook G4 and an Intel MacBook Pro, my intel machine has died and I would like to access some of the files on my USB Time Machine using my PBG4 However,the Time Machine icon does not appear on the desktop of the PBG4, is there anything I can do. The Intel MacBook won't open in Target Mode. If I remove the hard-drive and put it in a caddy, would the PPC be able to access it. Any help would be appreciated. PBG4 10.5.8 MacBook Pro 10.7.8 I think. It was up to date but I had not loaded Mountain Lion. Both computers have the Time Machine Icon in the menu bar.
