Move usr/bin/java in Terminal

After updating to OS X 10.11, my java stopped working. I read multiple places that I should do a:

sudo mv /usr/bin/java /usr/bin/java.old
sudo ln -ns /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin/java

But the issue is when I run the first line of code, I just get:

mv: rename /usr/bin/java to /usr/bin/java.old: Operation not permitted

Any ideas what I can do to fix this?


Seems like the problem with the new System Integration Protection (a.k.a rootless) that just got introduced with the new OS X.

You could try to disable the rootless in recovery mode through these steps :

  1. go to recovery mode (reboot and hold down Command + R keys simultaneously after you hear the startup chime)
  2. When the OS X Utilities screen appears, pull down the Utilities menu at the top of the screen instead, and choose Terminal
  3. run this command csrutil disable;reboot. This will reboot the laptop.

After that. Then, try to run the command again and see what will happen :D.
