Invite others to collaborate in Keynote on Mac
You can invite others to work with you on a presentation in real time by sending them a link to it. Everyone working on the presentation can see changes as they’re made.
By default, only the people you invite to collaborate on the presentation and who sign in to an Apple Account can open and make changes to it. However, you can change the access privileges so that anyone with the link can open it (without an Apple Account), or change the editing privileges so people can view, but not edit the presentation.
After you share a presentation, you can invite more people to join the presentation at any time. How you invite others depends on which access privilege is chosen (that is, whether invitees need to sign in to an Apple Account or not).
Tip: If the presentation is protected by a password, for security reasons don’t send the password with the link.
Participants can also present a shared slideshow with you. To learn more about multi-presenter slideshows, see Play a slideshow with multiple presenters.
