Question: MacBook: system preferences, and all other apps, quit unexpectly. Can't access anything.
I have a 2008 MacBook. All that shows on the upper bar (where Apple icon, time, battery percentage, wifi connection, etc, usually is) is from left to right is Finder File Edit View Go Window Help, then close to right side, coffee cup icon, blanks where other icons usually are, then flag, battery percentage, blank where wifi connection usually is, then day and time.
I can put my curser where the Apple icon usually is and the drop down menu appears, but nothing works. If I choose system preferences, for instance, I get the message 'system preferences quit unexpectedly while using the AppKit plug in'. When I click reopen, the same message comes up. Clicking 'report' does nothing. This happens with anything on the drop down menu except 'restart'. The computer will restart, but it reopens with all the same problems.
If I click 'shut down', a blank white square appears, so no options to choose from.
None of the files will open that are on my desktop except for MS Word docs.
None of the apps will open, so I can't access the internet, photos, music, or any other shortcut.
The word 'Finder' shows in the top bar, as I said, but nothing actually happens when I try to open anything.
I'm about ready to try to wipe the whole computer and reinstall.
