Arduino Micro not showing up in serial ports

[bugatti_9]

Hi, I'm new to the forum but have been using Arduino for quite some time. Recently, my arduino micro decided to not show up in the serial port chooser in the tools menu. I am somewhat familiar with the arduino controls and made sure i had selected the right board, my programmer was on arduinoISP and tried pressing the reset many different times in many different patterns. I have never had this problem before and it is really annoying me. I could really use some help. A couple of statistics:

Using arduino ide 1.8.19
on macos monterey on m1 Note: used the ide on m1 for quite some time and have never noticed an issue.

Much appreceation to anyone that could help me. its just not showing up. note: in the available serial port menu there are only two options:

devcu bluetooth incoming port
and
devcu wlan debug

it used to be 3 there was a comm usb modem port which recognized the board attached. trying to locate the problem, I hooked up my uno to the same port and it popped up on the right port. plugged the micro back in and it just wont show. up i though about the cord but i have used the micro with this cord for some time and never had an issue. it was also the cord that came with one of my other adafruit boards so its definately one designed for data transfer.

help much apprecieated

thanks,

I'm not familiar with Macs.

One question is if you have tried different cables? The cable that you're using might be a charge-only cable.

I have no idea what the equivalent of Windows device manager or Linux's lsusb/dmesg is on a Mac. That might tell you a bit more what's going on.

Hi sterretje, as i mentioned in the original post, the cable came with one of my other adafruit boards and ive never had an issue in the past with it.

Thanks for the tip though!

Upon quitting the ide, unpluggin the board and performing a full reset of the board, i then plugged it back in, opened the ide and it showed up under the right port. I closed the menu, then reopened it and "usb-modem" was gone! any ideas?

thanks
