The Dropbox app is no longer connecting on MacOS 15, unless I disable my firewall.

The local Dropbox app (209.3.3602) on my iMac is no longer connecting after I upgraded to MacOS Sequioa 15.0 (24A335).

I can only get it to work again after disabling the Firewall (Settings, Network, Firewall).

From other sources (ZDNet) I have understood that the upgraded Firewall now also blocks DNS lookup replies initiated from inside my network, so from the local Dropbox app for example.

Hoping for upgrade news from Cupertino...

  • This is the solution:

    sudo /usr/libexec/ApplicationFirewall/socketfilterfw --add /Applications/Dropbox.app

    and for any other app that no longer seems to work on MacOS 15 (like Firefox).

    Thanks Pedro!
