Pages suddenly refuses to save documents, saying I don't have permission

Hello Richard Worzel,

Thank you for reaching out in Apple Support Communities. Excellent job with verifying that you have permission to save documents in Pages and being an admin. To further troubleshoot this behavior which can help, we recommend to restart your Mac in safe mode. This helps to delete some system caches and more. Once you're in safe mode, please restart the Mac as normal and see if you can save documents in Pages. Here's how to restart your Mac in safe mode:

Start up your Mac with Apple silicon in safe mode

1. On your Mac, choose Apple menu  > Shut Down.

Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.

2. Press and hold the power button on your Mac until “Loading startup options” appears.

3. Select a volume.

4. Press and hold the Shift key, then click Continue in Safe Mode.

The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

Start up your Intel-based Mac in safe mode

1. Turn on or restart your Mac, then immediately press and hold the Shift key until you see the login window.

2. Log in to your Mac.

3. You might be asked to log in again.

On either the first or second login window, you should see “Safe Boot” in the menu bar.

We look forward to hearing back from you with an update.

Kind regards.
