Homebrew-cask: unidentified developer - ONLY through brew cask

[lantrix]

Description of issue

The app works perfectly, and this isn't a cask or feature request.
I searched the other issues and they don't seem to discuss this.

I find it strange that when I download 4.0.6 of gitkraken from their site the app is signed by the developer, and tells me as such.

When I download the SAME app via cask it gives me the known "The app can’t be opened because it is from an unidentified developer"

[lantrix]

I actually updated to 4.0.6 in #53717 because I thought maybe it was not signed by the developer, but it is.

I'm experiencing a related problem with multiple apps. Whenever I open such an app (not only the first time), I'm getting a progress bar saying "Verifying..." and then a dialog:

Casks affected:

• atom
• firefox
• spectacle
• transmission
• vlc
• google-chrome

Not all casks are affected. It works fine (no dialog, only on the first launch) for:

• veracrypt
• virtualbox

Here's my environment

No, it’s a bug. Please fill that template.

@wpiekutowski You case is working as expected.

[wpiekutowski]

@vitorgalvao thank you for a quick reply. I'm aware of this FAQ entry, however on 10.14 I see this dialog every time I open mentioned apps with:

• right click -> Open -> Open
• double left click
• open /Applications/Spectacle.app
• via Spotlight

This doesn't happen if an app is downloaded by user manually and "installed" by moving to /Applications.

Additional observation: My user account doesn't have admin privs ("Standard" account). I have a separate admin user. When I use homebrew, I first su - admin and then run various brew commands. I'm mentioning this because the only difference I've spotted so far is the ownership of an application directory. When installed with homebrew, it's owned by admin. When installed manually, I get an admin authentication propmpt when moving the app to /Application and after a succesful authentication ownership is set to my standard user.

Let me know if I should open a new issue about this.

Raised as a proper bug report #54072
