Hello, I recently tried to install Windows 10 using bootcamp, however that isn't easy at all. After a lot of searching on the web, I found that I was missing an option in bootcamp. I'm still trying to get this option working, using this youtube vid: However in this tutorial everything goes flawless. Everything went okay until the point I had to replace the edited file with the non-edited file. Ofcourse Apple wont let you change the file.. because.. well.. Apple. So, to change this file you have to disable SIP (csrutil disable). To do that you have to go in recovery mode because it won't work when booted normally. (terminal does find it though) So I went in recovery mode and tried it myself, however terminal can't find the 'csrutil' command at all. I'm on macOS 10.12.2 Sierra, when in recovery mode I get the option the restore to macOS Mountain Lion 10.8, not sure if this matters but it's there just in case. Hopefully you can help me! Regards, Timo Ps: Sorry for my bad english!
