Keynote

Use iCloud Drive with Keynote on Mac
When iCloud Drive is turned on for your device, it stores your presentations and keeps them up to date on your computers, iOS devices, and iPadOS devices where you’re signed in to the same Apple Account. You always see the latest versions of your presentations, no matter where you made your last edits.
For seamless syncing of presentations, use iCloud Drive and devices that meet these minimum system requirements: macOS 13, iOS 16, or iPadOS 16, or later. On iPhone or iPad, items stored in iCloud Drive appear in the document manager.
You can also use Keynote for iCloud to create and edit Keynote presentations using a supported web browser on a Mac computer or Windows device.
