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 using an Apple ID can access and make changes to it. You can instead allow access to anyone who has the link to the presentation, or allow people to view but not edit the presentation.
Participants can also present a shared slideshow with you. To learn more about multipresenter slideshows, see Play a slideshow with multiple presenters.
Invite people to collaborate
To invite others to collaborate on a presentation, make sure that you’re signed in with your Apple ID, you’ve set up Keynote to use iCloud Drive, and the presentation you want to share is stored in iCloud Drive.
With the presentation open, click
in the toolbar.If Collaborate isn’t showing in the pop-up menu at the top, click the pop-up menu, then choose Collaborate.
To change who can access the presentation, click the disclosure arrow below Collaborate, click the “Who can access” pop-up menu, then choose an option (if you don’t see these options, make sure the presentation in stored in iCloud):
Only invited people: Only people you invite who sign in with an Apple ID can open the presentation. Recipients who don’t have an Apple ID need to create one before they can open your shared presentation.
If you invite someone using an email address or phone number that isn’t associated with their Apple ID, they won’t be able to accept the invitation until they add the email address or phone number to their Apple ID. When they tap or click the link in the invitation, instructions appear.
Anyone with the link: Anyone who has the link to the shared presentation can tap or click the link to open the presentation.
To change who can make changes to the presentation, click the Permissions pop-up menu, then choose an option:
Can make changes: People can edit the shared presentation.
View only: People can view the shared presentation but not edit it. They can’t reply to or delete comments in the activity list, and when they join a presentation, no notifications appear.
Note: If you set access to “Only invited people” (in the previous step), you can change individual permission settings after you share the it.
If you don’t want all participants to be able to invite others, deselect “Allow others to invite.”
Choose a method for sending the invitation to collaborate:
AirDrop: Select or type the name of the recipient, then click Share Link. The recipient must be on the same network and must accept the file to receive it.
Mail or Messages: Type an email address or phone number for each recipient, add a note if you want, then click Send (for Mail) or press Enter (for Messages). A link to the file is sent to each recipient.
Notes: To share a link to the file in the Notes app, select or type the name of the recipients, click Share Link, choose the note where you want to save it (or create a new one), add text if you want, then click Save.
Invite with Link: Copy the file’s link, so you can send it or post it using any internet service that’s already set up on your Mac. Type an email address or phone number for each recipient, then click Copy Link. Open the app you want to use to share the link, click where you want to paste the link, then choose Edit > Paste (from the Edit menu at the top of your screen), or press Command-V on the keyboard.
Important: The link to the presentation that’s created when you click Collaborate includes the presentation’s title. If the title or content of the presentation is confidential, be sure to ask recipients not to forward the link to anyone else.
A checkmark appears on the Collaboration button 
to indicate that you’ve shared the presentation. After recipients accept the invitation, the number of participants joining you in the presentation appears to the right of the button 
.
Invite more people
If you’re the owner of a presentation whose access is set to “Only invited people,” or if the owner of a shared presentation gives you permission to add people, you can invite more people at any time.
Tip: If the presentation is protected by a password, for security reasons don’t send the password with the link.
Do one of the following:
Choose File > Manage Shared Presentation (from the File menu at the top of your screen).
Click
in the toolbar, then click Manage Shared Presentation. In iCloud Drive, Control-click the file, then choose Manage Shared Presentation.
Do one of the following:
Invite more people to collaborate: Use this method if you’re the owner of a shared presentation with access set to “Only invited people,” or if the presentation owner gave you permission to add more people. Click Share With More People, then click a method to invite your new participant. See Invite people to collaborate.
Send the link to more people: Use this method if presentation access is set to “Anyone with the link.” Click Copy Link, then click where you want to paste the link. Choose Edit > Paste (from the Edit menu at the top of your screen), or press Command-V on the keyboard.
Click Done.
Note: The link may appear in the body of the message as a stylized graphic with the presentation title—be sure not to edit or delete it.
Any participant can copy a link to a presentation and paste it somewhere else—for example, to save the link where they can easily access it. If the owner limited access to people they invite, the link only works for invited participants.
You can change the sharing settings for the new people after you send the link.
