I'm persistently getting an error "Skov is damaged and can't be opened". I extracted the folder from the disk image to my Desktop. I tried right-click->open with the same result (and Gatekeeper gives a different error anyway).

I'm still on El Capitan. Could that be the problem?

I have just tried it on my older Mac that still runs El Capitan. I downloaded the image from the website, opened it and copied the folder to the desktop. I had the same error as you ("Skov is damaged and can't be opened"). Then I went to System Preferences > Security and Confidentiality and I saw that "Allow applications downloaded from" was set to "Mac App Store and identified developers". I selected "Anywhere" and tried again: it worked. So the problem was really Gatekeeper.

Shouldn't right click and "Open" work? It doesn't work and I don't know if I want to disable gatekeeper.

Other people have helped me identify the cause of the problem (quarantine attribute on the app folder). I've uploaded a new dmg image. If you try to download it again it should work this time (I hope).

Doesn't work. Same problem.

But thanks for the tip about quarantine. I removed it from the folder and app with xattr and now I can start it.
