mac laptop copy paste to iphone not working

 Here are the steps:

• Open the Terminal app on your Mac (Applications > Utilities)

• Now, we will first delete Clipboard sharing and then enable it again. Here is how:

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

• Now, copy and paste this code and hit Enter:

defaults write ~/Library/Preferences/com.apple.coreservices.useractivityd.plist ClipboardSharingEnabled 1

• Now check if copy and paste is working.
