With the new system integrity protection in OS X 10.11 does it no longer makes sense not to run as an administrator for day to day use like is common safe computing practices? OS X malware is comparatively rare when compared to windows but I'm of the kind that rather' she safe than sorry. Don't use an antivirus program but do have separated accounts for my mac even though I'm the only user. One an administrator user and another standard one for typical use. Would really appreciate someone more knowledgeable than me to explain in more detail what SIP actually does in El Capitan.
