  1. I’m running a MacBook Pro 2015 model with Big Sur and my Bluetooth has been disabled. There is no Bluetooth Pane in system preferences and “no information found” in System report. I’ve tried to reset the Bluetooth module but has no effect. The and Bluetooth.prefPane files exist and appear to not been changes/corrupted. Any idea what I can do?

  2. I can no longer access system information on my imac. When I click on ‘About This Mac’, nothing happens. When I go to Finder, Applications and try to open ‘System Information’, I get the message ‘The application “System Information” is not open anymore. Hope you can help.
