My Mac Switches Audio Output From Bluetooth Headphones to Internal Speakers
This kind of issue has been widely noticed after the major updates of macOS from Mojave to Catalina. I would suggest you get the latest Catalina update that has been released couple of days ago. In other hand, try the following two resolutions which might help you.
- Open Finder
- Click on “Go”
- Then go to “Folder”
- Type on the search tab ’ /Library/Preferences’
- Look for a file with a filename “com.apple.Bluetooth.plist.
- Delete that file. Not to worry though as will auto-create a new copy of the Bluetooth file.
- Once file is deleted, restart your Mac device.
