"No ST-LINK detected..." when trying to "Run as" the project in STM32CubeIDE on MacOS 27

[Moustache2000]

Hi! 

When trying to run the code in STM32CubeIDE (“Run as”) I see the error

“No ST-LINK detected! Please connect ST-LINK and restart the debug session.”.

In error log I also see the message

“Cannot run program "/usr/local/bin/stlink-server" (in directory "/Users/<username>"): Exec failed, error: 86 (Bad CPU type in executable)”

This started to happen after updating to MacOS 27.0 (Golden Gate) from version 26. Before that it was working fine.

Also the board can be seen by STM32CubeProgrammer (see screenshot).

Also I installed as a separate package ST-LINK-SERVER 2.1.1 (https://www.st.com/en/development-tools/st-link-server.html)

Board: Nucleo-F446RE

Laptop: Apple M4 Pro with MacOS 27.0

IDE: STM32CubeIDE Version: 2.2.0 Build 29186_20260626_0934 (UTC)

I hate to suggest this but:- 

1.  completely uninstall cube IDE and reinstall it
2. after reset make sure cube programmer doesn’t capture the USB first ie run cube IDE first 
3. if that does not help I don’t know, driver issue maybe?

Thanks a lot! Looks like it helped!

I tried to completely remove IDE and stlink server. AI chat suggested these set of folders/files. I didn’t have all of them however. I’ll leave it here in case someone gets the same kind of issue

echo "1. Killing active processes..."
killall STM32CubeIDE ST-LINK_server stlink-server ST-LINK_gdbserver segger-jlink openocd 2>/dev/null

echo "2. Removing Application & App Data..."
sudo rm -rf /Applications/STM32CubeIDE.app
rm -rf ~/.stm32cubeide
rm -rf ~/Library/Preferences/com.st.stm32cube.ide.mcu.rcp.product.plist

rm -rf ~/Library/Saved\ Application\ State/com.st.stm32cube.ide.mcu.rcp.product.savedState

echo "3. Removing Firmware Repositories & Logs..."
rm -rf ~/STM32Cube/Repository
rm -rf ~/.stlink
rm -rf ~/Library/Logs/STMicroelectronics

echo "4. Removing ST-LINK Server & Debug Binaries..."
sudo rm -f /usr/local/bin/stlink-server
sudo rm -rf /usr/local/stlink-server
sudo rm -f /usr/local/bin/ST-LINK_gdbserver

echo "5. Cleaning macOS Package Receipts..."
sudo pkgutil --forget com.st.pkg.st-stlink-server 2>/dev/null
sudo pkgutil --pkgs | grep -i "stlink" | xargs -I {} sudo pkgutil --forget {} 2>/dev/null

echo "Done! STM32CubeIDE and ST-LINK services have been fully purged."

MacOS 26 is the latest supported version.

You may be able to get it to work on your own, but it’s not officially supported.

I encountered the same problem after upgrading to macOS 27 Golden Gate on an Apple silicon Mac.

CubeProgrammer detected the ST-LINK, but CubeIDE displayed “No ST-LINK detected” during ST-LINK firmware verification, with no Console output.

Running /usr/local/bin/stlink-server in Terminal revealed:
zsh: bad CPU type in executable

The installed ST-LINK server was Intel x86_64, although CubeIDE’s bundled GDB server was Apple silicon and could detect the probe.

Installing Rosetta resolved the problem:
softwareupdate --install-rosetta

​@Lina_DABASINSKAITE  Please ask the developer team to provide an Apple silicon native ST-LINK server, or detect and clearly explain the Rosetta dependency. The current “No ST-LINK detected” message hides the actual executable compatibility error.

Hello ​@rich.g.williams ​@Moustache2000  ​@Francois-No-ST-LINK 

As ​@TDK has mentioned in his comment the “No ST-LINK detected” error on macOS 27 is likely due to the fact that macOS 27 is not currently an officially supported host OS for STM32CubeIDE. The latest supported macOS version is macOS 26. While the IDE may still launch and work partially on macOS 27, ST-LINK detection and debug functionality are not guaranteed. For a fully supported setup, I recommend using macOS 26 or another supported operating system.

Understood, thanks for update.
