| ibook won't shut down
My iBook G4 ( 1.2 GHz, Mac OS X Ver 10.5.7 ) won't shut down from the Apple drop down menu. It does shut down if I hold the power key down, but I am concerned that will cause problems eventually. I have run disc utility and reset the PMU, no change. What could it be? I have read other threads but I didn't see how to fix it. Thanks.
