RF52-DK keeps mounting and unmounting on MacOS

Hello,

I use a RF52-DK board for flashing/debug Nordic microcontroller. When I connect the board on my mac, the "JLINK" volume is mounted/ unmounted every 2 seconds and I can't do anything.

  • Macbook Pro 13", 2020, Apple M1
  • MacOS 14.5 (23F79)
  • Segger Jlink software v. 7.76i
  • nRF connect Desktop v. 5.0.0

"Allow accessories to connect" is set to "Ask for New Accessories" in System Settings > Privacy & Security.

I tried to connect to the board with a new cable with no success.

Can anyone help me with this?
Thank you very much.

Aurelien
