Universal Clipboard not working from Mac to iPhone, workaround found

Universal Clipboard only worked from iPhone to Mac — fixed

I had a one-way Universal Clipboard problem: copying from my iPhone to my Mac worked, but copying from the Mac to the iPhone failed in every app. Both devices used the same Apple Account, Wi-Fi and Bluetooth were on, Handoff was enabled, and Safari Handoff was visible.

Restarting pboard, sharingd, and bluetoothd did not help. The following user-level Terminal commands fixed the problem on my Mac:

defaults write ~/Library/Preferences/com.apple.coreservices.useractivityd.plist ClipboardSharingEnabled -bool true

killall useractivityd

After running them, Mac-to-iPhone paste worked again. This is a community-reported workaround rather than an official Apple fix. I hope it helps others with the same one-way symptom.

Good find. The one-way behavior is a useful clue, especially since normal Handoff was already working.

I’d just add one caution for anyone trying this: ClipboardSharingEnabled is an undocumented preference, so I’d use the Terminal workaround only after the standard checks and a restart. Apple’s supported requirements are the same Apple Account, Wi-Fi, Bluetooth, Handoff, and nearby devices. Use Universal Clipboard to copy and paste between your Apple devices - Apple Support

Since your Mac-to-iPhone clipboard started working immediately after restarting useractivityd, this workaround may help others with that same specific one-way symptom.
