Hello,

if you are using macOS and STM32CubeIDE and need it productively you should currently refrain updating your macOS. Due to a bug in Eclipse (https://github.com/eclipse-platform/eclipse.platform.swt/issues/2621) text selection does no more work via dragging your mouse or using shift+arrows.

There is already a fix but STM32CubeIDE does not provide the fix as update as of now.

I already filed a case.

Hello @st_otto

In the meantime, STM32CubeIDE 1.19.0 is not supported on macOS 26.1, according to release note RN0114.

Bug observed in MacOS 26.2 with CubeIDE 2.0.0 as well.

And Eclipse 2025-06 (4.36.0).

To be fair (asking a lot) this is not an ST problem. Both Eclipse and CubeIDE worked properly prior to updating to MacOS 26.2. The people that complain that ST should be better at choosing when to release a system should remember that Apple radically changed how their UI works, ultimately breaking Eclipse and CubeIDE. This is also not the first time that Apple's alterations borked Eclipse and CubeIDE, don't you remember the upside-down splash screen? That was corrected by Eclipse AND Apple subsequently.

So, hang on for a while and fixes will be coming.

BTW, control-space code completion doesn't work too.
