Probes Not Found Error when attempting to connect to FRDM46lz board

Probes not found error M4 Pro Macbook Sequoia 15.6 while attempting to connect to FRDM46lz board in MCUXpresso. Fellow students with Macs have not encountered this issue. Have been working hard with university staff but not found a solution. Have already attempted plugging into difference ports, restarting device, changing privacy settings, creating a new project, and uninstalling and reinstalling MCUXpresso, among other things. Help would be greatly appreciated, thank you!

Hello @ottofhalb ,

Thanks for your post. Please open Device Manager and check whether the serial port has been successfully enumerated.

In addition, have you ever tried to update the OpenSDA?
OpenSDA Serial and Debug Adapter | NXP Semiconductors

You may refer to attached "Updating the OpenSDA Firmware.pdf".

Hope it helps.
