iMac waiting

Trying to send a photo/file from the iPhone 13 to the iMac. iMac is enabled "everyone". The iMac can see the iPhone. Using the Airdrop option to send a photo, and selecting "iMac" on the iPhone, it simply shows, "iMac waiting". There is no indication on the iMac that I can see, of being able to accept anything. Everything else is shared between the two devices. And I have an iPad 3 as well.
