macOS installation error: Bisq is damaged and can't be opened. You should move it to trash

If you are running already macOS Ventura (13.0+) you need to do following to be able to start Bisq:

  • Enter following command in Apple Terminal sudo xattr -rd com.apple.quarantine /Applications/Bisq.app
  • Hit enter and you will be prompted to enter your password to be able to execute the command as super user

I’ve done it, but it continue to send me same message…

which version of macOS are you using?

Ventura the last one 13.2.1

This confirms the findings I’ve come up with until now, not every ventura user will be unable to fix the issue following the article, as some of them are indeed able to install Bisq in the end, but every macos user who cannot install Bisq even using the guide, is using Ventura.
My usual suggestion is to install a linux VM and use bisq from there
