How do I link notes with attachments to reminders on macOS 15.3.1?

I believe I have your solution. I have a lot of trouble using this feature because it seems only work from my iPhone. And even then it does not always work perfect.

1. On iPhone, open your Note.
2. Tell Siri "remind me about this"
3. It then creates a Reminder that has the little Notes icon embedded in it.
4. Now in Reminders, you'll see it looks different because there's a little Note icon. Tap that and you'll launch straight into the Note (sometimes it's hard to tap just right). So this is basically adding a special shortcut to the Reminder. (This does not use the "share" or "URL link" etc. at all.)

Note:

-- This does not use the "share" feature at all.

-- Recently I've learned that with Siri + Apple Intelligence + ChatGPT makes this trickier because they think you're asking ChatGPT to remind of you something contextual. So I deactivated all of that to provide this example.

I create a note with our without attachment, I can 'share' it, but when I share to 'reminders' I got this :

So I can only share it to 'someone' reminder??

That's what I see. That's why I'm confused as to why you say "link" when you use "share." I take "share" to mean

"with someone."

To create a "link," I would drag it into Reminders, but that doesn't do anything.

I don't seem to have any problem doing what you describe. I didn't go beyond the address dialog as it sounded like you didn't even get there.

Try restarting.
