Google quickly admitted the error , and that indeed is a Chrome bug led to the problems. If you turn off the system integrity protection function (System Integrity Protection, SIP) in macOS system, Chrome's bug will affect the file system. In addition to the impact of this bug close SIP-enabled macOS, it will not affect SIP-macOS, and 10.11 the previous version of OS X that is not supported by SIP.
