Ask for support!
I plan to add some records into hosts file under /etc/hosts. but when I try to change the file, I got error. unable to write a readonly file.
I even use the root account to try to change it, still failed. below is the file
sh-3.2# id uid=0(root) gid=0(wheel) groups=0(wheel),1(daemon),2(kmem),3(sys),4(tty),5(operator),8(procview),9(procmod),12(everyone),20(staff),29(certusers),61(localaccounts),80(admin),703(com.apple.sharepoint.group.3),702(com.apple.sharepoint.group.2),33(_appstore),98(_lpadmin),100(_lpoperator),204(_developer),250(_analyticsusers),395(com.apple.access_ftp),398(com.apple.access_screensharing),399(com.apple.access_ssh),400(com.apple.access_remote_ae),701(com.apple.sharepoint.group.1) sh-3.2# ls -l /etc/hosts -rw-r--r-- 1 root wheel 688 10 25 08:19 /etc/hosts sh-3.2#
I try to change the permission of this file, still failed.
sh-3.2# chmod 777 hosts chmod: Unable to change file mode on hosts: Operation not permitted
and after I disable SIP, still failed.
However when I try to change other files in same folder(/etc), will work. only hosts file didn’t work.
anyone can help me? great thanks!
