Autocomplete not working on IDE v2.0.0

Autocomplete is not working on v2.0.0, also didn't work on v1.19.

MacOS 15.5
Macbook Pro 16"
2,3 GHz 8-Core Intel Core i9

Any suggestions?

Hello @diktril 

 

On macOS, Ctrl + Space is NOT handled by STM32CubeIDE — it is intercepted by macOS because it is the default shortcut for “Change Input Source”.

This is why Content Assist does not appear in CubeIDE.

You need to change macOS shortcut:

-   Open System Settings

-  Go to Keyboard → Keyboard Shortcuts

-  Open Input Sources

-  Disable or change the shortcut for: Select the previous input source ; Select the next input source

After disabling it, restart STM32CubeIDE and Ctrl+Space will work normally.
