For Apple Sequoia users,
The IRCAM protection no longer works by default because the WIFI address (MAC address) on which the protection is based is private. To fix the problem, you need to set the option to Off, then authorize ASAP and you should be able to set it to private (Fixed yes Rotating) afterwards.
1 Choose Apple menu > System Settings, then click Wi-Fi in the sidebar.
2 Click the Details button or More Info button next to the network name.
3 From the menu next to Private Wi-Fi Address, choose Off
Thanks @guillot for the tip !
