I keep getting “can’t connect to serial port” errors on a M2 Macbook Air & freshly downloaded Chrome, any ideas?

What have you tried to fix it? Have you followed the flashing directions carefully?

Heres the 2 recommended troubleshooting items from the linked firmware page:

Serial port never shows up? Try activating Programing Mode

Hold the center button while turning the device off and then on to place Mezzz into Programing Mode. No leds will light up in this mode but the port will be visible.

Can’t connect to serial port?

Make sure other programs aren’t trying to use the port, including any IDE, browser, game engine, vj software etc.

I did all of those things carefully more than once yesterday to no avail.

Today I repeated the process and successfully connected & updated the firmware. :ghost:

Is there a step that was missed in the instructions?

Why would I download the .bin file and then not upload it anywhere?
