Airdrop - Older MacBook cannot find new MacBook
Airdrop has been working between Macbook Pro (Late 2013) with Sierra and other Macs and iPhones. But it cannot find my new MacBook Air (2020) with Big Sur. MacBook Air can find MacBook pro.
How could I make the Old MacBook pro find the new MacBook air so that I can use Airdrop feature?
Thanks!
MacBook Pro 13″, macOS 10.12
