To reproduce

Use this command to reproduce

arduino-cli_0.34.1_macOS_ARM64 % ./arduino-cli upload -p /dev/cu.usbmodem1201 --fqbn arduino:mbed_nano:nano33ble --input-dir .

I can reproduce and confirm this is a regression on MacOSX.

Also, this seems already fixed on master, I guess I can cherry-pick the commits and release a patched version 0.34.2

Fixed in version 0.34.2.
