I have been dealing with AppleCare and they seem to be a little stumpted, so I am going to try everyone else. When I boot up, I no longer get the items in the menu bar like date, time, wireless, bluetooth status, etc. In the Apple Menu, things like "About this Mac", reboot, shut down, etc. Do nothing. System Preferences gives me a beachball. I have just recently did a CLEAN install. The install worked fine. I then changed the time to EST and updated to 10.5.7. I did not do all the other updates...wanted to take it slow. I am back to the issue again! There is nothing installed on this computer other than Leopard! It is a 15" Macbook Pro 4GB memory, Intel processor...etc. At first Apple thought a 3rd party app may have corrupted some preferences. This can not be the case.... Thoughts? Could it be bad hardware??? The machine is just over 2 years old.
