How can I remove Photos.app from Mac OSX El Capitan? Appzapper doesn't work
Appcleaner doesn't work
The typical Terminal Command i use doesn't work


Is the only way to doe this by disable SIP (System Integrity Protection)?
Try AppZapper, i always use it but idk if it really delete Apple's apps

AppZapper can delete .app and also every configuration file that it have

EDIT: i've found this, the guy in that tutorial is using CleanMyMac3 to do it. Hope it can help you
