So when stapling my installer package file I get the following output:
We do not know how to deal with trailer version 58519. Exepected 1
Processing:
Properties are {
NSURLIsDirectoryKey = 0;
NSURLIsPackageKey = 0;
NSURLIsSymbolicLinkKey = 0;
NSURLLocalizedTypeDescriptionKey = "Installer package";
NSURLTypeIdentifierKey = "com.apple.installer-package-archive";
"_NSURLIsApplicationKey" = 0;
}
Terminator Trailer size must be 0, not 2639
{magic: t8lr, version: 1, type: 2, length: 2639}
Found expected ticket at 16671916 with length of 2639
Sig Type is RSA. Length is 3
Sig Type is CMS. Length is 3
Package MyPackage.pkg uses a checksum of size 20
The staple and validate action worked!
It all seems to actually work and the installer works fine on a vanilla macOS Catalina beta, but I just wanted to check that the messages relating to 'trailers' are not an issue?
