Sharing Notes on Catalina
Follow these steps if the issue occurred immediately after upgrading
Open the Terminal app, which is in the Utilities folder of your Applications folder.
-
Type this command in Terminal:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed
Press Return and wait for the Terminal prompt—which ends in $—to reappear. It may take a few minutes.
- Quit Terminal.
And later go to Apple menu > System Preferences, click Extensions, and make sure that the Markup and sharing features are turned on in the Actions and Share Menu sections too after running the above command.
