I have been using this Nano for 4 days now, over the few pervious days I have been able to create some different projects like a custom stopwatch that lasts 5 hours and 30 minutes. Just today though when I was working on Tetris, my Mac couldn't detect my Nano. This was strange so I checked the provided wire I was using and no visible deformities, and the Nano looks fine, I've restarted, shut down and hard wiped the ports and the Mac itself. I have gone through the terminal and put in the code ls /dev/tty.* to detect the ports and all I've gotten back was console debugger and bluetooth incoming port. I've proceeded to try those, they didn't work. Please help!
Hi @wlcode4830. You described the Arduino board you are uploading to as "Nano". Something that can be confusing is there are multiple boards with "Nano" in their name. We need to be certain of exactly which one you have. The reason is that the problem might be caused by the IDE not being correctly configured for your specific board.
Please tell us which of the following boards you are attempting to upload to:
- classic Nano (including clone/derivative boards as long as they have the ATmega328P microcontroller)
- Nano 33 IoT
- Nano 33 BLE
- Nano 33 BLE Sense
- Nano ESP32
- Nano Every
- Nano Matter
- Nano RP2040 Connect
- ...or something else?
If you aren't sure which one you have, you can provide a picture of the board or a link to the place you bought it from and we'll see if we can identify it.
classic Nano
Please try this troubleshooting procedure and then report your results in a reply on this forum thread:
This procedure is not intended to solve the problem. The purpose is to gather more information.
- Unplug the USB cable of your Arduino board from your computer if it is currently connected.
- Click the Apple logo on the left side of the menu bar at the top of the screen ("Apple menu").
- Select "System Settings..." from the menu.
- A "System Settings" window will open. Click "General" in the menu on the left side of the window.
ⓘ You may need to scroll the menu down to see "General". - Click "About" on the panel at the right side of the "System Settings" window.
- The "About" panel will open. Click the "System Report..." button at the bottom of the panel.
- The "System Information" window will now open. Select Hardware > USB from the tree on the left side of the window.
- Take note of the contents of the "USB Device Tree" panel of the "System Information" window.
- Connect the Arduino board to your computer with a USB cable.
- Select File > Refresh Information from the menu bar.
Do you see any new device appear in the "USB Device Tree" panel of the "System Information" window after doing the last step?
I already did that it doesn't show anything except the apple bus and when I click on that nothing happens
hard wiped the ports and the Mac itself
How would one hard wipe a port? And the Mac, you reinstalled it from scratch?
Are you referring to a USB cable? If so, is it the same cable you were using when the board was detected?
Make sure the cable is fully inserted into the USB socket on the board and on the Mac.
Found the problem, the Mac doesn't have the driver to detect the the Chip that the Arduino I have is using

cleared all known connections from the ports and reconnected them
Thanks for the update. Was the problem solved after you installed a driver?
