Hey Siri on iMac 24"

[circatee]

Can someone with an 24" iMac confirm is 'Hey Siri' works for them?
For the love of testing, I cannot get it to work via 'Hey Siri'. Works fine via the button, or even holding the microphone button on the keyboard. And, the option of 'Hey Siri' is on in Settings, too.

Thanks in advance

SOLVED! This is a brand new 24" iMac, and the plastic around the edge of the unit was not removed. Thus, the microphone was covered - LOL
