I was using Continuity, Handoff, Universal clipboard, Personal hotspot remote activation, Airdrop, unlock by watches etc. between MacBook Air 2015, iPhone 7 and Watches 2, but a few weeks ago it stopped working on Mac (between watches and iPhone it still works).
- All devices have the newest software and are compatible.
- Tried restarts, iCloud logout/login on same account.
- iCloud cloud services works.
- In safe boot mode it works, however
kextstat | grep -v com.appleshows nothing
