Hi all, I used app zapper, to remove some of the apple programs I don't use, like messages and FaceTime etc. Since then when I go into preferences I am unable to open iCloud settings. It says unable to load preference pane. I've noticed in Library/application support. I also have no access to Apple Push Service and Com.Apple.TCC Is there a way to restore what ever's been deleted, causing this issue. Or do I need to reinstall the whole OS?
