What is a .plist file?
Preference and configuration files in macOS use property lists (plists) to specify the attributes, or properties, of an app or process. An example is the preferences .plist for the Finder in the Library/Preferences/ folder of a user’s home folder. The file is named com.apple.
The main macOS Bluetooth device cache is in the”/Library/Preferences/com.apple.Bluetooth.plist“. Due to corruption etc, you may have to delete the numerous Bluetooth .plist files. See the example below!
Note: Deleting this file “com.apple.Bluetooth.plist“ONLY will not resolve this issue as mentioned in this guide “Cannot open Bluetooth Preference Pane because it is not available on Mac“.
