OS X 10.11 El Capitan is the most secure Operating System Apple has ever made. It is secured by the System Integrity Protection that limits the apps and users in root level.
Whether you are a developer or a normal user, no one is recommended to disable System Integrity Protection (SIP). If you do so, Malware, Virus or other infected files would get a chance to use this permission to make changes in your system or preinstalled files. This could make your Mac vulnerable and risk your own data and privacy.
If SIP in enabled, you can still uninstall programs on Mac, but can’t remove any system apps or modify system files. If you want to do something like that, you need to disable SIP, and then it can be done. After making changes it can be enabled again, and we will tell you how. If you are using OS X 10.10 Yosemite or older version, you can remove system apps without disabling SIP.
Note : If you don’t know what you are doing, never try it. I will not be responsible for anything happens ahead. Removing system apps or making changes in system files may make your system unstable.
