Restore an earlier presentation version in Keynote on Mac
Every time you save a presentation, Keynote saves it as a new version. As a result, you can browse earlier versions, save a copy of an earlier version, or restore a presentation to an earlier version.
You can also copy and paste text and objects from an earlier version to the current version.
View, copy, and restore an earlier version
With the presentation open, choose File > Revert To (from the File menu at the top of your screen), then choose Browse All Versions.
The window refreshes to show a thumbnail of your current version on the left and a stack of thumbnails of the previous versions on the right. A vertical timeline appears on the right side of the screen.
To view earlier versions, click tick marks along the timeline or click the arrows next to the stack of presentation thumbnails on the right, then click a thumbnail to view the version full size.
Do one of the following:
Edit the current version: Click the thumbnail on the left, make your changes, then click Done.
Restore a previous version: Click Restore below its thumbnail. A restored version replaces the current version.
Save a copy of the version displayed on the right as a new presentation: Hold down the Option key on the keyboard, then click Restore a Copy. Keynote opens the copy in a new window, where you can edit it and save it with a new name. The original version also remains open in its own window.
Close this view and return to your presentation: Click Done.
Revert to your last opened or last saved version
A reverted version replaces the current version. To keep the current version and an earlier one, save a copy of the earlier version, as described in the previous task.
With the current version of your presentation open, choose File > Revert To (from the File menu at the top of your screen), then choose one of the following (you may not see all of these options):
Last Opened: All changes you made to the presentation since you last opened it are deleted.
Last Saved: All changes you made to the presentation since you last saved it are deleted.
Click Restore or Done.
Copy slides, text, and objects from previous versions
You can copy slides, text, and objects from previous versions of a presentation and paste them into the current version.
With the current version of your presentation open, choose File > Revert To > Browse All Versions (from the File menu at the top of your screen).
The timeline for the presentation opens. The current version appears in the window on the left. Earlier versions appear in the window on the right.
Locate the version with the content you want to copy, then click to select the text or objects and choose Edit > Copy (move the pointer to the top of the screen to see the Edit menu).
In the current presentation on the left, click where you want to place the content, then choose Edit > Paste.
If you add a password to a presentation or change an existing password, the password applies only to the version where the password was added or changed and to subsequent versions.
Note: If the presentation is shared with others, anyone with editing permission can copy and restore only the versions created after you shared the presentation. Anyone with View Only permission has no access to earlier versions. To prevent others from restoring an unprotected version of the presentation or a version with an older password, stop sharing the presentation, add a unique password to it, then share the presentation again.
