Bambu Lab Software Bambu Studio
1

Product: Bambu Studio for MacOS
Version: v01.09.07.52
Operating System: macOS 14.5 (23F79)

Summary:

The Filament Settings window in Bambu Studio does not close when attempting to use the red close button in the top-left corner of the window, causing the app to become unresponsive and requiring a force quit.

Steps to Reproduce:

  1. Open Bambu Studio.
  2. Click on the Filament Gear Icon.
  3. Select “Custom Filaments.”
  4. Click on the edit icon of a filament.
  5. Click “Edit Preset.”
  6. Try closing the window by clicking the red close button in the top-left corner of the UI.

Expected Result:

The Filament Settings window should close when the red close button is clicked.

Actual Result:

The Filament Settings window remains open, and the close action is not executed. The app becomes unresponsive, and the only way to close Bambu Studio is by force quitting it.

Workaround:

To close the application, the user is required to force quit by:

  1. Pressing Command + Option + Escape and selecting Bambu Studio from the “Force Quit Applications” window.
  2. Alternatively, using the Activity Monitor to force quit the app.

Additional Notes:

  • This issue seems isolated to the Filament Settings window.
  • No error message or feedback is provided when attempting to close the window.
  • A force quit is consistently required after reproducing this bug.

Severity: High

I have the same issue and I have a feeling one of the force quits also caused one of my custom settings to be corrupt – not showing up on machine but showing up locally on Mac.

Same problem.
macOS 13.6.9 (22G830)
and after I force quit Bambu Studio again…
Version 1.10.1.50

I can evidently set things (they appear after force-quitting and reopening Studio), I just can’t close the window or ignore it and get back to work. All of the drop down menus are greyed out as well.

I’m having the same problem. After creating a new filament profile, I cannot close the dialog box.
