The device displays the Keynote Remote menu.
Note: Tap Allow if you’re asked to allow Keynote to find and connect to devices on your local network.
Go to the Keynote app on your Mac, then choose Keynote > Settings (from the Keynote menu at the top of your screen).
Click Remote at the top of the settings window, then select Enable.
Click Link next to the device you want to use as a remote.
A four-digit code appears on the Mac and on the device.
Verify that the four-digit codes match, click Confirm, then close Keynote settings.
After the devices are linked, you can control the presentation from the remote.
You must first set up the iPhone or iPad to be a remote control, as described in the previous task. To turn your device into a remote using Handoff, iPadOS devices, and Mac computers that have the latest version of Keynote to connect over Wi-Fi whenever they’re in close proximity, even when they aren’t on the same Wi-Fi network. If you have difficulty using Keynote Remote with older devices or Mac computers over Wi-Fi, try adding them to the same Wi-Fi network.
Note: The old Keynote Remote app previously available from the App Store is no longer supported.
