Issue with RP Pico / Mac OS Tahoe?

[rwboyer]

Completely new to tinygo (but not go) just tried to test my dev environment to make sure everything is working properly (which seems to be) but ran into an issue I assume is related to Mac OS 26.

• Wrote a small test program (onboard LED with PWM and serial output w/ println) for the Pico which I've used before and used the default tinygo flash -target=pico -monitor which failed . (the build and flash work fine without the -monitor)
• Investigation revealed that the serial port doesn't seem to be showing up as a new device on the Mac.
• Connected the Pico to a linux machine I have and the serial port fired up instantly with no issue when using tinygo flash -target=pico -monitor....

Doesn't really seem to be a problem with tinygo itself.

Wondering if anyone else has seen this issue on Mac OS 26 with the Pico serial port and might have an idea how to fix it. Or if I missed it what the name of it should be?

You ever find a solution? I seem to be hitting up against the same problem myself tonight.
