When i restart, the top bar with the date and time, networks, battery life etc.. all disappears and theres only the finder icon which gets stuck for some reason and wouldnt work either!
When restarting my macbook pro, all the options on the top right corner of the screen disappear ( battery life, Wifi, languages etc..) when i try to show them in system preferences once i click on network preferences the whole system preferences goes Not responding and i have to force quit it. the only way i found to bring them back is restarting my computer a number of times till they just come back alone. not sure what the problem is??? now i never shut down my computer cause i am worried i'll lose them again and for months i just put to sleep when i am done since nothing happens to them when its on sleep once i shut it down and turn it on again the same thing happens.
appreciate any answers...
You sure you're in the /Users/username/Library/Preferences/ folder? If yes, then that's your issue. That plist controls the right-hand menu bar.
log into a newly created admin user account and see if the problem persists. Then, check its Preference folder for that plist file.
