not valid for use in process using Library Validation

[AlJohri]

I'm getting this error: not valid for use in process using Library Validation: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?)

Full Error:

Process 2908 launched: '/Users/atul/Desktop/App Store.app/Contents/MacOS/App Store' (x86_64)
dyld: warning: could not load inserted library '/Users/atul/Development/ssl-kill-switch2/build/Release/SSLKillSwitch.framework/Versions/A/SSLKillSwitch' into hardened process because no suitable image found.  Did find:

I'm trying to view the requests to/from the App Store. I codesigned using: codesign -f --deep -s "Self-signed Applications" build/Release/SSLKillSwitch.framework

I tried both using the Dylib method and lldb and got the same error.

I have SIP disabled and I even copied the binary from /Applications to ~/Desktop.

$ csrutil status

Configuration:

	Kext Signing: disabled
	Filesystem Protections: disabled
	Debugging Restrictions: disabled

This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

Am I doing something wrong?

I read somewhere the key needs to have an OU (organizational unit) but that also didn't work:

I think this is because the macOS has hardened runtime for the app. Thus using lldb and dyld insert is not enough. Refer #52
