Fing.app considered as malicious software

FLlikeEiffel

OS: macOS 10.14.6 
Hi,
when launching the Fing desktop application, I get a warning saying: "Fing.app can't be opened because Apple cannot check it for malicious software \n This software needs to be updated. Contact the developer for more information". Pressing the OK button from the warning popup window makes the application to close. While keeping the warning popup window, Fing is started and can be used but again pressing the OK button will close the application. Any idea how to fix it? Thanks.

Sure, I tried that but it didn't change anything, still getting the same warning and behavior. 

Can you share the screenshot of the error so I can seek developers advice and investigate further?

Have you tried uninstalling the application and reinstalling?  If not, give that a shot and see if it works.  Unfortunately I don't have any MacOS devices running Mojave so I cannot comment if it may be an OS issue.

Hi @FLlikeEiffel
Can you try to download a new file from the link: https://www.fing.com/products/fing-desktop
and then move the package to the Desktop and then hold Control and click the file to launch the installer. When the message appears, click Continue.
Also, if the issue persists, can you confirm what kind of administrative rights do you have on the system? Thanks

Actually, the Mac desktop is not an installer, it's a binary which is copied to the applications' folder. And, yes I do have root privileges for the installation of the binary.

Can you try to dowload file from this link: https://www.fing.com/products/fing-desktop-download-mac and then check?

I did that twice with the exact same link and with the exact same result: version 2.1.0 from July 24th, 2020.

 Can you confirm if you installed it by dragging into the Application folder, or you trying to use it without installing? A video recording will be helpful (Quicktime can record a screencast)

Alternatively, you can try these solutions:

Please let me know if anything changes.

The 1st option does work with my version of the OS by overriding the standard authorizations using the admin account. But then you need to use the admin privileges every time you want to launch the application. The fireebok article refers to an alternative solution which is "update and notarize the app" that should be done by the developer. I guess it corresponds to what is described in some apple recommendations: https://developer.apple.com/documentation/xcode/notarizing_macos_software_before_distribution
N.B.: the application was indeed dragged to the Applications folder
