I’ve been having intermittent issues with my Bluetooth on my 2013 MBPR. I thought at first it might be my Logitech mouse but the Apple Magic Mouse and Keyboard won’t stay connected either. Sometimes it takes a reboot to get the Bluetooth working again. Other times it just takes me switching my Logitech Master to a unifying adapter for a few minutes and then back to Bluetooth. I’ve tried reaching out to Apple support but they don’t seem to care about my old Mac.
Few things I’ve tried:
- deleting all of the Bluetooth files from the library so they would rebuild
- rolling back an OS
- upgrading to the latest OS
- trying bata OS
- using third-party Bluetooth adapter - this one didn’t really work at all
