Can't install PIA, "Private internet access installer is damaged and cannot be opened"
I am trying to install PIA on a mid-2015 MacBook Pro 15'' with MacOS High Sierra 10.13.4. Every time I try to use the installer, I get the error message "Private Internet Access Installer is damaged and can't be opened. You should eject the disk image". This is a brand new installation of MacOS. I am able to open the disk image itself, it's only the installer that doesn't work. I have tried this with versions 75-80 with no success.
