How to use Hook for Apple Calendar?

Welcome to Hookmark forum, @Wilson .

What’s your script version? You can find it in Hookmark about window.

There is a “+” button at the bottom of the app list for full disk access. You can click on it and add Hookmark to the list.

Thank you

Ok I found it, turning it on makes the link work, but once I refused the full disk, it returns to unlinkable. Are there some updates or thoughts on this issue?

I am glad it works, @Wilson .

Sorry we don’t know why this happens yet. Quite often, it happens after you update the software.Apple must have changed something.
But not everyone needs full disk access. Perhaps each mac has its own setting.
