It seems that TT Selection Toys is causing the Toolbar Customization option to break in my SketchUp 2024 on macOS 15 (Sequoia).
When I right-click the menu bar and select “Customize Toolbar,” the toolbar does the shake-effect but doesn’t display the picker drawer.
Disabling TT Selection Toys resolved the issue, so it seems to be related to that plugin. This problem doesn’t occur in my 2023 version.
Any idea?
