STM32CubeMX.app fails to launch via Finder on macOS systems using case-sensitive APFS

[CaptainKrall]

The application bundle contains Contents/MacOs instead of the required Contents/MacOS. On case-sensitive file systems, this prevents LaunchServices/Finder from starting the app.

• The binary runs correctly when launched directly from Terminal.
• Renaming MacOs → MacOS also seems to solve the issue.

Seems to be an error in the ST packaging system.

Hello @CaptainKrall 

I have performed a test using macOS Tahoe 26.0 (Intel) and was able to successfully launch the latest version of STM32CubeMX 6.16.1 via Finder.

The application bundle  contains Contents/MacOs .

Could you please provide more details about your environment:

1- Your macOS version
2- Your CPU architecture (Intel or ARM)
3- The STM32CubeMX version you are trying to launch
This information will help us better understand and reproduce the issue.

Hello Ghofrane,

did you try it from a system on case-sensitive file system? I won't expect the problem to arise on an Apple default installation, but as a developer, I had to re-install macOS on case-sensitive volume because of my UNIX tools.

My system:

• macOS Tahoe 26.2
• M4 Max (ARM CPU)
• STM32CubeMX version 6.16.1

Cheers, Marc
