check and uncheck doesnt do anything. the same with the wi-fi. same with Bluetooth. everything show that they are unchecked. when actually all of them are checked.
Well, this is a bit like taking a sledghammer to crack a walnut, but in your case I would try resetting all your User prefs to default by deleting the entire contents of this folder (do NOT delete the folder itself)
~/Library/Preferences
There are three (at least) Library folders; make sure you get the right on by doing it this way:
1. Click on the Finder face in the Dock.
2. Click on 'Go' in the menu bar at the top of the screen.
3. Hold down the 'option' key on your keyboard. You should see 'Library' in the Go menu. Click on it and release the 'option' key.
4. In the window that opens, go to the Preferences folder. Select everything inside it and hit 'command' and 'delete' on your keyboard.
5. Restart your mac.
After login, any improvement?
(Warning: since this resets all your user preferences back to default, you'll have to set up any changes you made previously such as Trackpad, Screensavers, Mouse, Security & Privacy etc etc.).
