On mac catalina 10.15.1 when the app is opened I get this message:

“Skipper” 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 on 9 November 2019 from www.skipper18.com.

How can this be solved?

we're aware of this new restriction from Apple.

We already updated all our CI and have new binaries with positive notarized stamps.

Please download it from the beta section:


This beta also contains some GUI fixes caused by the latest OSX bugs

Edit: Currently we're working on auto-updater fixes and some more Catalina issues.
