Hello Kamil
The blank side panels and non-functional page editor in Mendix Studio Pro 10.24.13 on Mac M1 are often caused by corrupted local configuration or cache files. Since Studio Pro for macOS is currently in Beta, it is more susceptible to these UI initialization bugs compared to the Windows version.
1. Clear Local Cache and Configuration
The most effective fix for blank panels is to manually delete the Mendix application data stored on your Mac. This forces the Modeler to recreate the UI components from scratch.
Step 1: Completely close Mendix Studio Pro.
Step 2: Open Finder and use the "Go to Folder" shortcut (Cmd + Shift + G).
Step 3: Delete (or rename to back up) the following folders:
~/Library/Application Support/Mendix
~/Library/Caches/Mendix
~/Library/Logs/Mendix
Step 4: Relaunch Studio Pro and open your project.
2. Perform a Clean Reinstall
If clearing the cache does not resolve the issue, a deep reinstall is recommended to ensure no leftover beta files are interfering.
Uninstall: Move the Studio Pro application to the Trash.
Wipe Residue: Ensure the folders mentioned in Step 1 are deleted again.
Restart: Restart your Mac to clear any remaining system-level hooks or cached background processes.
Reinstall: Download a fresh installer for version 10.24.13 (or a later patch if available) from the Mendix Marketplace.
3. Check for Known Beta Limitations
Native Page Preview: Note that native mobile page previews are currently not supported in Studio Pro on macOS. While this shouldn't turn the entire editor blank, it can cause specific UI elements to fail to render.
Theme Conflicts: Although you tried changing themes, sometimes the "Auto (System theme)" setting fails to inherit properly on Mac. Try setting it specifically to Light or Dark in Preferences > Appearance, then restart the app.
Next Steps
If the issue persists, would you like me to help you find the specific Mendix Support ticket page or look for a newer 10.24.x patch release that specifically addresses UI rendering on Apple Silicon?
