Track changes in Pages on Mac
You can track changes to body text and text in text boxes, shapes, and footnotes (including document and section endnotes). When tracking is turned on, changed text appears in a different color from the surrounding text, and change bars appear in the margin.
To review, approve, and reject changes, you can use the review toolbar and the Comments & Changes sidebar.

Note: If the document is shared on iCloud and you turn on change tracking, only people using Pages on a Mac, iOS device, or iPadOS device can edit the document. People who don’t have the Pages app and are using Pages for iCloud to collaborate can only view the document.
If you send your document to someone else and they open it in Pages on their iPhone or iPad, the document opens in Final View (with change tracking hidden). To see additions and deletions, they must tap at the top of the screen.
