Microbit identified by not flashed on MacOS Sequoia 15.1.1 (24B91)

[deejaygraham]

What were you trying to do?

Flash a program to an attached microbit

What steps did you take to trigger the issue?

After upgrading MacOS from Big Sur and using the latest mu editor, attached microbit USB port. Port shows that microbit is attached and bottom left of editor shows that it identifies that a microbit has been detected ("Detected new microbit device"). Pressed the flash button.

What did you expect to happen?

Program to be flashed to device

What actually happened?

Pressing "flash" brings up the file dialog and cancelling shows the usual "Could not find an attached microbit" message.

Operating System Version

MacOS Sequoia 15.1.1

Mu Version

1.2.0

Other Info

Made sure that mu and Terminal has full access to disk under Settings > Privacy and Security. Tried the same procedure with another machine running Big Sur and this flashed as expected.

Unfortunately an update in macOS has caused the MICROBIT drive to be missnamed as NO NAME, so Mu probably won't be able to find it because of that:

• macOS 15 Sequoia USB drive name shows as NO NAME ARMmbed/DAPLink#1082

Apple has been informed, but we don't know when it might be fixed. In the meantime a micro:bit firmware update will be released soon, but that is currently being developed.

Thank you for the update
