Hi there! I see you’re having trouble making a backup with the Bookmory app. Can you tell me a bit more about what happens when you try to back up? For example, do you get any error messages, or does the process just not start or complete? Also, are you trying to back up on your Macintosh running OS X 10.15.7?

This info will help me guide you better! Meanwhile, I can share some general steps we can try to resolve backup issues with Bookmory on your Mac.

1. Check App Version: Make sure Bookmory is updated to the latest version available. Updates often fix bugs related to backups.

2. Stable Network Connection: Since backups might sync data to a server, ensure your Mac is connected to a reliable internet connection.

3. Manual Backup to Cloud/Local: Bookmory sometimes requires manually initiating backup or sync. Look in the app’s settings for export or backup options and trigger a backup manually.

4. Storage Space: Verify your Mac has enough free space to create backup files.

5. App Permissions: Confirm Bookmory has the necessary permissions to access local storage and network on your Mac.

6. Restart the App & Device: Sometimes, simply quitting and restarting the app or rebooting your Mac can clear temporary problems.

If these basic steps don’t do the trick, we can then explore more specific solutions such as examining the backup file location or checking for software conflicts.

Could you try these steps and let me know what happens? Also, if there’s any message or behavior detail, please share it with me. That way I can assist you further!
