Hi, have you been able to fix this? I have the same issue.. :(

Thanks for a quick response, i am not sure what command i should use to run the syspolicy_check. After running syspolicy_check distribution /Users/username/Documents/WattAttack-Mac-Shipping.pkg App has failed one or more pre-distribution checks. Codesign Error File: /Users/___username___Documents/WattAttack-Mac-Shipping.pkg Severity: Fatal Full Error: File is not signed at all. Type: Notary Error Notary Ticket Missing File: /Users/username/Documents/WattAttack-Mac-Shipping.pkg Severity: Fatal Full Error: A Notarization ticket is not stapled to this application. Type: Distribution Error Though it is signed with the 3rd Party Mac Developer Installer: certificate...

I 've managed to start my app now i can see the following crash report information: Termination Reason: Namespace DYLD, Code 1 Library missing Library not loaded: @loader_path/libsteam_api.dylib Referenced from: <......B-3DDF-3AD6-B3C8-C39C3771A824> /Applications/WattAttack-Mac-Shipping.app/Contents/MacOS/WattAttack-Mac-Shipping Reason: tried: '/Applications/WattAttack-Mac-Shipping.app/Contents/MacOS/libsteam_api.dylib' (code signature invalid in <.......-0547-37ED-844E-89C9CABACBCA> '/Applications/WattAttack-Mac-Shipping.app/Contents/MacOS/libsteam_api.dylib' (errno=1) sliceOffset=0x00004000, codeBlobOffset=0x00027B70, codeBlobSize=0x000055F0) (terminated at launch; ignore backtrace) I've read different articles related to this code signing error but cant figure out how to fix the problem :(
