MacOS - Handoff slow copy & set

Hello all,

I use very often in macOS the function “Handoff” to copy files between my Mac and iPhone.

I noticed that since Big sur the copy function takes a little longer. Under Mojave the copy was instant between Mac and iPhone.

Is this happening to me or does anyone else have this problem as well?

It is a MacBook Pro Late 2017 and an iPhone XS.

Best regards

I have found the solution. The cause was the Mac Firewall. If you configure the firewall to block all incoming connections, then the Handoff function behaves as described.
