Handoff not working for clipboard between macOS Tahoe and iPhones

Found the solution on redit! <https://www.reddit.com/r/mac/comments/1fo2976/solution_to_handoff_not_working_between_mac_and/>

Final Solution: Open Terminal on the Mac and enter the following commands:

   defaults delete ~/Library/Preferences/com.apple.coreservices.useractivityd.plist
   killall useractivityd 

(This deletes the useractivityd file and restarts the useractivityd process.)

Thank you to shesabadone on redit

I have now tried this with two MacBooks (both updated to macOS Tahoe) and two iPhones... Handoff no longer works between devices. Copy text, from any app, on the MacBook, and attempt to paste it on the iPhone. The iPhone has no history of the clipboard.

Original Title: Handoff broken with Tahoe

I am not seeing this issue....macOS26 and iOS26

Have you shut down and restarted both devices(?) router/modem(?)

Also, if the solution is reboot the router, there's something majorly wrong with these updates.

I never said it was a "solution"; it is a trouble shooting step in an effort to resolve your issue.
