You can Cite While You Write with Apple Pages.
Pages includes EndNote Citation commands on the Insert menu and the Edit menu.
EndNote commands were implemented in Pages by Apple, with the cooperation of Clarivate Analytics and using Cite While You Write technology provided by Clarivate Analytics. Changes to Cite While You Write in Pages may not coincide with updates to EndNote.
If you use Microsoft Word as your word processor, see How to Cite While You Write with Microsoft Word.
If you use a word processor other than Microsoft Word or Apple Pages, or an older version of these word processors, save your document as an RTF file and use Format Paper.
To create a standalone bibliography that is not based on the citations in a paper, see Independent Bibliographies.
Note: Only one word processor at a time should be open when inserting citations and formatting documents.
