STM32CubeIDE 2.0.0 on macOS Tahoe 26.2 (Apple Silicon M4): text selection not visible

[CColo.2]

Ambiente

Sistema operativo Mac Tahoe 26.2 (25C56)

Apple Silicon M4

STM32CubeIDE 2.0.0 (x86_64, ejecutándose bajo Rosetta 2)

Asunto

STM32CubeIDE se inicia correctamente, pero la selección de texto no se representa visualmente en ninguna parte del IDE (editor, consola, vistas).

La selección del mouse y del teclado no muestra ningún resaltado.

Copiar/pegar funciona normalmente , lo que indica que la selección existe internamente pero no se muestra.

La selección de texto funciona correctamente en otras aplicaciones de macOS.

Pasos para reproducir

1. Inicie STM32CubeIDE en Rosetta:

arch -x86_64 /Aplicaciones/ST/STM32CubeIDE.app/Contenidos/MacOS/STM32CubeIDE

2.Abra cualquier archivo fuente.

3.Intenta seleccionar texto.

Solución de problemas realizados

Instalación de Rosetta 2 verificada.

Restablecer preferencias y espacio de trabajo.

Espacio de trabajo limpio probado.

 Deshabilitado el renderizado SWT Metal/gestos a través de opciones .ini.

El problema persiste.

Subject

STM32CubeIDE starts correctly, but text selection is not visually rendered anywhere in the IDE (editor, console, or views).

---

Description

Text selection using either mouse or keyboard is not visually highlighted anywhere in STM32CubeIDE.

Copy/paste operations work normally, which indicates that the text selection exists internally but is not rendered on screen.

Text selection works correctly in all other macOS applications.

---

Steps to Reproduce

1. Launch STM32CubeIDE under Rosetta:

   arch -x86_64 /Applications/ST/STM32CubeIDE.app/Contents/MacOS/STM32CubeIDE

2. Open any source file.

3. Attempt to select text using mouse or keyboard.

Troubleshooting Performed

Verified Rosetta 2 installation

Reset IDE preferences and workspace

Tested with a clean workspace

Disabled SWT Metal rendering / gesture support via .ini options

The issue persists.

Hello CColo.2,

This behavior is raised to development team for investigation via this ticket number: 224479.

I will keep you posted.

ok, Thank you.

I have the exact same issue on MacOS Tahoe 26.2. @Aimen1 Is there an update or workaround for this? 

[grisom13]

There are workarounds available already from users. So sad ST is not providing anything now. 

https://community.st.com/t5/stm32cubeide-mcus/warning-macos-update-to-26-1-breaks-eclipse-text-selection/td-p/854200

The fix for me is crashing the APP with an error, but other report its working

Hello FOFI,

macOS 26.2 was released in December 2025 after the release of the STM32CubeIDE 2.0.0. Therefore, STM32CubeIDE 2.0.0 is supported only on the earlier macOS 26 Tahoe version, as stated in RN114.

The issue will be fixed in a future release.

Hello @Aimen1

Thank you for getting back to me and for being involved in the community. This now makes complete sense to me. Would you be able to share a timeline for the next release? If it is going to take a long time, I am considering downgrading my machine, as I am eager to get started with my STM32F446RE.
