Hello, 

I recently switched to a new Macbook os Tahoe. I can't flash MCU. I see some errors pop. CubeMX detects ST link V3 minie, but can't flash it. Same come with the ST link upgrade. The old Mac with the Sequoia can do the job. Any ideas please ?

UPD. So it looks like Tahoe glitch nothing to deal with V3 mini.

 

Another issue - I can't highlight a text code any more in main.c. I can do command+A in console but its not working in any code window.

UPD2. 

After further testing, I’ve confirmed that text selection does occur, but the highlighting is not visually rendered. The selected region is actually active — typing or deleting after an invisible selection correctly replaces or removes all the intended lines.

 

The console section working fine. The code section not

Hello,

I was using CubeIDE 1.9

Tried 2.0.0 version. Same issue with text selection does occur, but the highlighting is not visually rendered.
