Hi richtack,
Yes, you can add desktop reminders through the Mac app, and then you'll get reminder notifications just like you want. :)

Let us know if we can help with anything else!

That's how I have it set up. I even tried deleting and adding back the desktop setting and re-testing it.

If this matters, I don't' see Remember the Milk listed under the mac's System Preferences:Notifications.

Happy to send someone screenshots, if easier!

In that case you may want to review your reminders settings more generally, i.e. in the Daily Digest and Reminders sections of the Account Settings.

It's possible you have the notifications set up but don't have the Digest or Reminders enabled?

Keep us posted!

Yes, I have desktop checked for reminders. I even tried turning off all other forms for reminders, to see if something was just taking precedence over the desktop, but no luck.

Okay, I actually figured it out. I had to check "Remind me at the time tasks start", which has always been there, but with the iPhone I never needed to click. I think i'm looking good, thanks!

You can add multiple reminder methods, so you shouldn't need to turn them off. In fact, enabling another method could help make sure they're working.

Just to make sure though, I was wondering about the separate sections—not in the Contact Preferences, but the checkboxes in each of the Daily Digest and Reminders sections. Contact Preferences sets "where" to send reminders, and those sections set "when" to send them.

Hope this helps!
