How do I uninstall java 6 from el capitan?

[dugbug]

i used the apple installer to put java on for minecraft, then minecraft announced a java-free native mac minecraft so i want to remove the cruft. Interestingly it puts java in /usr/bin area. The sudo lines provided by oracle don't remove anything from /usr/bin. I take it this may be the no-admin lockdown?

Will a subsequent public beta remove java?

thanks

(edit: minecraft not java free just self-contained with native mac launcher)

Yeah, that would be interesting to find out.

well I did this and it seems to work.
1. disable rootless:
boot with command-R and in resulting recovery mode open terminal.
In terminal type: csrutil disable
reboot
(don't worry this is reversible)

2. Uninstall the java crap
Open terminal and entering:
sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefpane

These do not remove the java crap in usr/bin though. I deleted the java files (by using timestamp of when added) from /usr/bin.

3. Rebooted back into recovery mode and through terminal entered:
csrutil enable

Done. I probably destroyed my install but I cannot see java anywhere.

After upgrading to beta 6 and GM candidate, java-6-se wasn't installed anymore, so I tried out the minecraft stage launcher and their latest one from their site. Neither works for me. I have to install java to make it work..

Did you remove actual binaries or just aliases to the JavaVM.framework in /System/Library/Frameworks? I wouldn’t delete anything from there. I don’t have Java installed, but I still have that alias in /usr/bin pointing towards the framework, which was created on 3 September. I haven’t installed anything lately, only the El Capitan GM. So I assume the system will create that framework and alias regardless.

You can check with the terminal command java -version to see whether Java is installed.

You may want to clear here also - Oracle puts jdk stuff here (if you installed that in addition to jre).

cd /Library/Java/JavaVirtualMachines
ls (to see what you have)
sudo rm -rf jdk1.8.0_25.jdk (or whatever version)

Yeah the Mac native installer is busted. It worked last week. Minecraft.net posts indicate lots of users having issues

the native mac installer now works... disable antivirus web shield first though.
