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.

Turn on tracking: Choose Edit > Track Changes (from the Edit menu at the top of your screen). If the review toolbar is showing above your document, you can also click Track Changes in the toolbar.
Turn off tracking: Click
