ST-Link server is required error after macOS update

[Carl_]

Hello, I have been using the same cubeIDE debugger options for several months and have not had any major issues. However i recently updated to the latest macOS 15.0 release (not necessarily the cause, but it's the only change that comes to mind) and since then i've been getting the following error:

I have reinstalled the stlink server as recommended in:
https://community.st.com/t5/stm32cubeide-mcus/st-link-server-is-required-to-launch-the-debug-session/td-p/69617
and 
https://community.st.com/t5/stm32-mcus-boards-and-hardware/cubeide-does-not-see-st-link-server/td-p/149158

This has not fixed it and the stlink-server appears to be installed properly as i can use it via the CLI. I have also tried reinstalling the cubeIDE and used different versions of the cubeIDE. 

Has anyone encountered something similar or have any idea on what this could be?

EDIT:
I can also host a server from the CLI and connect to it from the cubeIDE via the "Connect to remote GDB server" option.

Apparently launching the app from the terminal with sudo solves this, so it appears to be a permissions issue.

Got the same identical problem on macOS sequoia 15, thanks for the solution

Hi Carl, 

I had the same issue. I think the guilty one is the upgrade to Sequoia 15, as CubeIDE and stlink-server are not fully supported.

For the moment, the way to get around it is to launch your IDE from a Terminal:

sudo /Applications/STM32CubeIDE.app/Contents/MacOS/STM32CubeIDE

It worked great for me.

Actually its the PATH available to GUI app. There's no need to use sudo.
