I have upgraded from Yosemite to El Capitan. Before running the installer, it warned me that the installer would be unable to create a recovery partition or install FileVault. Not sure why but I installed anyway. Now I need to temporarily disable SIP but because there is no recovery partition, when I reboot while holding Command-R, it takes me into internet recovery which takes about 10 minutes to load. I then launch Terminal and run "csrutil disable" and it doesn't work. How can I disable and re-enable SIP?
