Hi there! I understand the Zion app on your Mac (OS X 10.15.7) opens to the users list page showing your user, but you can't exit that page to access the menus. Just to get a better grasp, does the app respond to any clicks or key presses at all? For example, do menu buttons or other controls seem to activate, or is it completely stuck on that screen?

In the meantime, here’s a step-by-step approach we can try to troubleshoot this:

1. Restart the Zion app: Quit the app completely by right-clicking its icon in the Dock and choosing Quit (or using Command + Q), then reopen it to see if the menu becomes accessible.

2. Check for any stuck interface: Sometimes macOS apps can get stuck if a dialog or overlay is open but not visible. Try pressing the Escape (Esc) key or clicking outside the app window if there are multiple windows, to see if anything closes.

3. Look for hidden menus or sidebar: Sometimes menus are toggled via keyboard shortcuts or toolbar icons. Try pressing Command + M or Command + , (comma) to see if any menu or preferences window appears. Also, check for small hamburger (≡) icons or menu bars that might activate the menu.

4. Clear the app cache or preferences: Corrupted cache or preferences can cause UI issues. You can try resetting Zion's preferences by going to the Finder, pressing Command + Shift + G to open the Go to Folder dialog, then entering ~/Library/Preferences/ and locating any files named like com.zionapp.plist or similar. Move those files to the Desktop (to back them up) and restart the app to see if menus become functional.

5. Update the app and OS: Make sure your Zion app is up to date. Also, while macOS 10.15.7 (Catalina) is still supported by many apps, it could cause compatibility issues if the app expects features from newer OS versions.

6. Check for app-specific issues: If the app has an online help or support, look there for known bugs related to the users list screen. Since this is a somewhat specific app behavior, you might consider reinstalling the app after backing up any important data.

If you’ve already tried some of these or need help with any step, please let me know! Also, is there any error message or specific action that seems to cause it to get stuck on the user list? That will help me guide you better.

Are you satisfied with this approach so far?
