iPhone 13 Pro (iOS 16.4)
Mac Pro (10.13.6)
I only have partial Handoff and Continuity features but that may be due to my older Mac.
• A few minutes ago I only had one-way Universal Clipboard. iPhone -> Mac only. After playing around for a few minutes (toggled BT on phone), I was able to get Mac -> iPhone to work. Universal Clipboard is working both ways again.
• Phone calls work and I can pick up calls on the Mac, however, once the call is transferred to the iPhone or when initially picked up on the iPhone, the option to transfer it back to the Mac is gone. This used to work. Sometimes the incoming call continues to ring on the Mac after it's been answered on the phone.
• Reminders does nothing in both directions.
• Notes triggers it but it never brings up the note itself. Same with Messages, it triggers it, but the relevant message does not pop up. Getting a few "Handoff could not be completed" error messages on the Mac, which I never saw before.
• Mail Handoff is working great in both directions.
• Safari still seem to Handoff both ways (however open tabs are not shared between Mac & iPhone in both directions - outdated Safari?)
I will admit, my Mac OS has been on 10.13.6 for a while, so I have to give credit to iOS for recent improved reliability with Handoff and Continuity over the last couple years. It's trying and likely failing due to my Mac OS, as opposed to not even trying and doing nothing, which was more common a couple years back.
In the past, this procedure has worked every time to restore Handoff and Continuity whenever it decided to completely stop working in one direction.
