Cannot mount microbit v2 on MacBook Air

Hi

I have a new microbit v2, which I can connect to over bluetooth with my iphone.

I would like to connect it to my laptop now, but cannot get it to mount as a USB mass storage device. I have tired USB cables which I know work (data, not only power). It just won’t mount. I’ve checked in the USB Device Tree, and don’t see anything there either.

Any tips?

I’m running MacOS 12.3.1
