Single user boot : remove read only My OS keeps rebooting since I installed photoshop.

Save mode didn't help.

Trying now too boot on single user, I have a UI to unlock my user account (the mac is encrypted) then I have the command line.

I'm trying to remove everything from Adobe on the launch agent but I can't

sudo rm -rf com.adobe.AAM.Uploader-1.0.plist returns "read only file system" and don't even ask for my password!

Am I good for a reinstall or anything I can do to remove theses files / or fix my boot issue

I'm running 10.11 



Update: I forget I need to mount the HD first.  I'm trying now
Fsck followed by mount -uw / fixed my problem.
