Fix for handoff issues after Ventura 13.7 update
I never had a problem with handoff until the latest OS updates. My fix, which worked:
Turn off handoff on both devices.
System settings - General - Airdrop and Handoff
Restart both devices.
My devices are an iPhone 15 Pro and a Macbook Pro 13" 2017.
MacBook Pro 13″, macOS 13.7
