/System/Library/LaunchAgents is locked in El Capitan
I'm trying to achieve this: Make my password protected SSH key expire or timeout after a while
In Yosemite, this worked fantastic, in El Capitan, using sudo, the files in /System/Libary/LaunchAgents is completely locked :( I cannot chmod, write, or chown the files.
Using Finder -> Get info, the locked checkbox is disabled for the folder and the files in it (changing owner using finder doesn't work too).
Solution 1:
El Capitan adds a new security feature named System Integrity Protection (SIP). Among other things, SIP prevents parties other than Apple from adding, deleting or modifying directories and files stored in certain directories:
/bin
/sbin
/usr
/System
Apple has indicated that the following directories are available for developers to access:
/usr/local
/Applications
/Library
~/Library
All directories in /usr except for /usr/local are protected by SIP.
Solution 2:
In my case, it was the new System Integrity Protection feature in El Capitan. I disabled that in recovery mode using this link :
- Boot into recovery mode
- Click Utilities at the top, and then Terminal
- Type in
csrutil disable
