There is no login.keychain file in my High Sierra.Cant build titanium My KeychainAccess.app never creates the login.keychain file. So, I can't build titanium Application. If I create a new PC account there is no login.keychain file. If I reset default keychain there is also no login.keychain file.

appc ti build -K ${HOME}/Library/Keycahains/login.keychain
You have the wrong path for the login.keychain file.

You need to look in ~/Library/Keychains/ which means that your Titanium command becomes:

appc ti build -K ${HOME}/Library/Keychains/login.keychain
