Downloaded the app on my Mac and am not able to even open it.

I get this error message:

“Bisq” can’t be opened because Apple cannot check it for malicious software.  
This software needs to be updated. Contact the developer for more information.  
Chrome downloaded this file today at 6:18 AM from bisq.network.

Any ideas on how to solve this please? Thank you!

There’s some release notes dedicated to MacOs Catalina. [Release v1.5.4 · bisq-network/bisq · GitHub](https://github.com/bisq-network/bisq/releases/tag/v1.5.4)  
If you’re worried about Bisq being malicious, verifying the signatures should be enough, it’s just that Mac doesn’t like you to have software they don’t control.
