Setup

• Firmware: CircuitPython 6.2.0 beta 3 (en_US)
• Board: Raspberry Pi Pico
• Host: Apple MacOS Big Sur 11.2.2 on MacBook Pro 2014

Reproduce

1. Load this code as code.py

import time
import board
from digitalio import DigitalInOut, Pull
import usb_hid
from adafruit_hid.mouse import Mouse

button = DigitalInOut(board.GP16)
button.pull = Pull.DOWN
mouse = Mouse(usb_hid.devices)

while True:
    time.sleep(0.1)
    if button.value:
        print('CLICK!')
        mouse.click(Mouse.LEFT_BUTTON)

2. Connect to host OS via USB cable.
3. Push the button.

Expected results

• Mouse clicks are performed on pushing the button.
• It should work in any operative system.

Actual results

• MacOS recognises there is a mouse (see below), but fails to perform a mouse click.
• It does not work either in MacOS recovery mode (no user config).
• Works as expected on Windows 10.
• Works as expected on GNU/Linux.
• Works as expected on PC BIOS.
• No errors nor warnings are shown in the stdout.

Additional notes.

• Mouse movement and wheel does not work either, with same results regarding OS' (it works in everything but MacOS).
• Mouse usb_hid.device is present as expected with 0x01 page and 0x02 usage.
• MacOS actually detects there is a mouse connected since the mouse config menu goes from this

Thanks.
