I purchased Mozilla VPN, and tried to install on MacOs. Installation displayed "Install failed: The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." Sadly, it is not easy to cancel the payment. Here is the log from the installer Jul 23 14:31:46 Bo-MBP Installer[93297]: Package Authoring Error: <background> has an unsupported MIME type: image/data Jul 23 14:31:46 Bo-MBP Installer[93297]: Package Authoring Error: <background_scaling> has an unsupported MIME type: X-NSObject/NSNumber Jul 23 14:31:46 Bo-MBP Installer[93297]: Package Authoring Error: <background_alignment> has an unsupported MIME type: X-NSObject/NSNumber Jul 23 14:31:46 Bo-MBP Installer[93297]: Package Authoring Error: <layout-direction> has an unsupported MIME type: X-NSObject/NSNumber Jul 23 14:31:46 Bo-MBP Installer[93297]: Could not load resource readme: (null) Jul 23 14:31:46 Bo-MBP Installer[93297]: Could not load resource license: (null) Jul 23 14:31:59 Bo-MBP installd[679]: PackageKit: ----- Begin install ----- Jul 23 14:32:02 Bo-MBP installd[679]: PackageKit: Install Failed: Error Domain=PKInstallErrorDomain Code=112 "An error occurred while running scripts from the package “MozillaVPN.pkg”."
