Big Sur Upgrade

by conroyw on Tue Dec 29, 2020 8:40 am

After an upgrade to Big Sur on my Mac, I no longer see the Metro board or the USB ports. Anyone have any thoughts on how to get the ports back live. I already reloaded the FTDI drivers.

Try double clicking the reset button to go into "boot mode" and check for serial ports. Got to cmd and execute the commands below. You should see the device in the file viewer.

Code: Select all | TOGGLE FULL SIZE
ls /dev/tty.*
ls /dev/cu.*

Only port that shows up is the Bluetooth-Incoming-Port

Bill's Mac-->ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port
Bill's Mac-->ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port

Did you double click the reset and wait for a bit? I don't have a mac computer but I have a windows one and when I double click the reset button, wait for 15 sec, it creates a new com port and file manager sees it. Try it and wait for a minute or so.

I'm having this same problem.

(beginner, here) I just got my Adafruit Metro 328 Starter Pack, plugged the Metro into my MacBook, opened Terminal, entered ls /dev/cu* and I keep getting /dev/cu.Bluetooth-Incoming-Port

I double-clicked reset as the above user suggested but it didn't work. Suggestions?
thanks

Same issue here - I have a number of boards including Metro M0, ItsyBitsy M0 and Trinket M0. All these boards were fine with previous MacOS 10.x (so I know boards/usb cables are good)
Since Big Sur, none of them show up as virtual ports. I can still push code to them with the Arduino IDE - but without serial connectivity its hard to debug (my circuitrpy editors are also useless).

I know there's a bunch of advice on the Arduino forum - I have tried updating Java, and reinstalling the latest IDE(s). I realize that Apple changed things up in the latest OS, but was hoping there might be some suggestions here from devs since they are Adafruit boards.

Thanks.

Sorry to say, I am reluctantly giving up on Metro boards and Big Sur, and mothballing my stack of Metro Minis until I can find a Windows laptop. I've followed all the recommendations, downloaded the drivers, installed, uninstalled and even went back to a clean install with a clean download. The driver downloads properly, installs, and gets authorized but will not load, so no port ever appears under /dev/cu* (can see the driver is present but unloaded in System Report/Extensions and using terminal (kextload) to force load doesn't do it).

The whole idea of Arduino was plug and play and while I'm sure the signing and authentication on Mac is a huge pain, it still seems to be an unresolved issue months after this thread. I support Adafruit because I believe in the mission and that the best way to support you is to buy stuff, but in return I need it to work.

I eventually got Big Sur to work with my Metro board by deleting the arduino ide and performing a clean install.
