With the update (10.14.4) that came to MacOS mojave iTunes 12.6.5 is no longer supported. I made a research via the forums and copied the plist of iTunes 12.9.4 and changed the plist in iTunes 12.6.5 with the plist I copied. While doing all that sip was closed. Will changing the plist result in problems in the future? Will I face any issues If I open Sip?
