No Ports Recognized with IDE 2.0.3 ARM64 build (Apple M1) on Mac Ventura

[jeffmikels]

Describe the problem

Using the 2.0.3 build for native Apple Silicon works just fine on Monterey, but on Ventura no ports are recognized.

The workaround is to use 2.0.2 under Rosetta. I have not tested the 2.0.3 Intel build, so I don't know if the problem arose with 2.0.3 in general or with the Apple Silicon build specifically.

To reproduce

• Install 2.0.3 ARM64 build on Mac Ventura
• Run it
• Plug in an Arduino Board
• No ports recognized in the IDE
• even though ls /dev/cu.* will correctly show the usb serial device

Expected behavior

I would expect the IDE to discover the board or at least recognize the existence of the serial port.

Arduino IDE version

2.0.3 ARM64

Operating system

macOS

Operating system version

Ventura (13.1)

Additional context

No response

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

Hi @jeffmikels. Thanks for your report. I am also using the Apple Silicon build of Arduino IDE 2.0.3 with macOS Ventura and the ports of my boards are shown in Arduino IDE, so the problem is not universal.

I think the best way to proceed with the investigation is to take a look at the logs generated by Arduino IDE to see whether there is a clue there. You can access the logs by running Arduino IDE from the command line.

Please do this:

1. Open your Applications folder.
2. Open Utilities.
3. Double-click on "Terminal".
4. Type the following command in the Terminal window:

   "/Applications/Arduino IDE.app/Contents/MacOS/Arduino IDE"
   

5. Press Enter
6. Wait for Arduino IDE to finish starting.
7. Switch back to the Terminal window.
8. Press ⌘+A.
   This will select all the text in the Terminal window.
9. Press ⌘+C.
   This will copy the selected text to the clipboard.
10. Click on the "Leave a comment" field here on this GitHub issue.
11. Press ⌘+V.
    This will paste the output into the code block.
12. Click the Comment button to make the reply.

I am also having this issue with my Arduino R3 Clone. It works fin in Windows 11 but on MAC Ventura on my M1 it doesn't show any ports. However it does show a serial port in System Report on the MAC when its plugged in.

@jeffmikels @SauceCrusty try installing rosetta? See also #1818. Consider adding the macos tag to this issue.

FWIW, can not reproduce this problem with IDE 2.0.2 with AVR platform 1.8.3 (same as reported in this issue) with MacOS Ventura running on M1 Ultra, uploading to a genuine Arduino Leonardo board.

[PaulStoffregen]

Same test works fine with IDE 2.0.3 (x86 version running with Rosetta)

[PaulStoffregen]

And for completeness, also works fine with IDE 2.0.3 M1 version, this time with AVR platform 1.8.6 installed.

[SauceCrusty]

Not sure why or how but when I tried again I was able to see my ports and upload my sketch.

Closing due to lack of response to my question from 2 weeks ago, and because @SauceCrusty is no longer able to reproduce the fault.

@jeffmikels if you will provide the requested information by commenting here, I'll be happy to re-open this issue.

I don't have access to a Ventura machine right now. 😞
