Leopard install not working on PowerBook g4
I have a PowerBook g4 867mhz with 640mb of ram. It has 40gbs of space. When I turn it on it boots like normal. Then it shows my desktop. There is no dock. No menu bar. No icons. Please help! The sound works. And I also get a mouse.
PowerBook G4 (12-inch), Mac OS X (10.5.8), i bought this on ebay.
