Q: Pages quit unexpectedly since the day was 5.6.2

Hello cicogne,

Thanks for using Apple Support Communities.

I see from your post that Pages is crashing whenever you're trying to launch it.  To get started with troubleshooting this issue, I'd like you to try and open Pages with the Shift key held down on your keyboard.  This will prevent any previous documents from opening at launch.  

To temporarily prevent an app from re-opening its documents and windows, hold the Shift key while you open the app.

If the issue persists after that, then I'd like you to please try opening Pages in a new user account:

How to test with another user account

You can figure out if unexpected behavior is related to user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.

Create a test user account

1. From the Apple menu, choose System Preferences.
2. Click the Users & Groups icon in the System Preferences window.
3. Click the lock icon, then enter an administrator name and password.
4. Click the Add button (+) below the list of users.
5. Choose a type of user from the New Account pop-up menu.
6. Give the user a full name, account name, and password.
7. Click OK.
8. Close the System Preferences window.

If there are documents from your original user account that you want to test with, place a copy of these items in the Shared folder in the Users folder. Press the Option key while dragging a file to this folder to create a copy.

Log in to the test user account

Log out of your current user account by choosing Log Out from the Apple menu, then log in to the new account you created. If you're prompted to sign in with your iCloud account or Apple ID when you log in, skip this step.

Try reproducing the issue

Try the same steps that caused the unexpected behavior to appear before. For example, if you were unable to print, try printing from this user account. If you were unable to connect to the Internet, try browsing a website from this user account.

How to test an issue in another user account on your Mac

If it still happens in a new user, then please delete and reinstall the Pages application.

Apps downloaded from the App Store: Click the Launchpad icon  in the Dock, hold down an app’s icon until all the icons begin to jiggle, then click an app’s delete button . If you later want the app, you can reinstall it from the App Store.

 If it doesn't happen in a new user, then I would like you to please remove some user files for Pages:

1. Open a Finder window
2. In the Menu bar click View
3. Hold the Option key on your keyboard and click on Library
4. Navigate to the following locations, and move the items to the desktop: ~/Library/Containers/com.apple.iWork.Pages/Data/Library/Preferences/co m.apple.iWork.Pages.plist and ~/Library/Containers/com.apple.iWork.Pages/Data/Library/Caches
5. Re-open Pages

Take care.
