Why cant i airdrop things to my macbook pro 2020

Try rebooting both devices.

Make sure the OS on both devices is completely up to date.

These two things have always worked for me when AirDrop stops working. Of course check out the article @brbo linked for more details on how to use AirDrop.

If you want to use iPhone or iPad to airdrop ... this Apple support article may help
