Mac OSX Gatekeeper protects its users from installing untrusted software. Sling tv app works but not mac. Since Venn Audio products are not verified by Apple at this time, here’s a short guide to getting them working.
If you were hoping to revert back to High Sierra, or install an older OS X on a partition or VM, you will not be able to get the old installer if you are running Mojave. Hmm seems properly signed. I assume you are in Mojave. Try doing the following: 1 - Remove the app; 2 - restart mac; 3 - Go to terminal; 4 - Run 'sudo kextcache -clear-staging' 5 - Restart mac; 6 - Download and install volta.app; Let me know if it helped – Ricardo Anjos Feb 6 '19 at 9:00.
Mojave/High Sierra
Depending on your settings, you may see a message, “the developer cannot be verified”. If you receive this message, try to follow these steps:
Go into System Preferences → Security and Privacy.
On the first tab, when an unsigned application is blocked from loading, there is an ‘Open anyway’ box which appears there.
Click it!
Catalina
Catalina ramps up the security requirements and not only requires the developers to be verified, but the software to be notarized (scanned for malware). It also has a more complicated process for allow unverified software.
The following are instructions adapted from the good people at LoudMax. Mac app store excel.
Download Untrusted Apps
Open Terminal.
Disable Gatekeeper: type in sudo spctl --master-disable
Enter your password when prompted. (You must be an admin user on the computer.)
Go to System Preferences → Security and Privacy → General → Allow apps downloaded from.
Select ‘Anywhere’.
Install and run your Venn Audio plugin. (You may need to restart the computer before.)
Re-enable Gatekeeper:sudo spctl --master-enable
Again, enter your password if prompted.
