Home Forums Networks & Cross-Platform Networking Problem with AirDrop

I am trying to airdrop some stuff from my MacBook pro to my iMac. The airdrop on the iMac (once I click on it) only shows the airdrop icon and the message about what it can do. There is no option to choose "only in contacts or everyone" or anything else. I have blue tooth enabled on both devices and actually turned it off on all other devices since I can't get it to work. They are both connected to wifi.

I obviously can't transfer (though I've tried) anything from my Mac via Airdrop to the iMac until it shows it can receive by giving me the option of how to receive it mentioned above.

What else can I do to make the airdrop option work on my iMac? iMac has High Sierra and my MacBook has Catalina, but I don't think that should make a difference as I can airdrop stuff from my MacBook to my iPhone no problem,

Hi Rita,

The challenge before you is the different age of the two operating systems....

This LINK to the Apple Support forum may provide some additional useful info.

The part that caught my eye was having an Airdrop window open on the receiving older machine in advance AND ensuring that it wasn't blocking incoming connections on the Security PrefPane.

Let us know what happens.

I opened Airdrop on the older Mac first and still no "allow me to be discovered by" choice. Also, no "find an older Mac" was not an option when I tried to airdrop from one to the other. I followed your link and followed those directions. One was to unblock any apps I choose in the firewall. Airdrop was not offered under the apps. After looking online again in some places it said it was a known issue with iMac and High Sierra but no known solutions. . Thank you.
