Pages unexpectedly quit. How can I restore it ?
When I open PAGES to type a document it unexpectedly quits. How can I restore?
What version of Pages and on what operating system?
Press and hold the shift key while launching Pages. See if that fixes the issue, provided you are not attempting to open an incompatible or damaged document. If you are on Sonoma, you need Pages v14.1.
Apple has a dedicated Pages for Mac community for these type of questions.
