Sorry, I'm new here... I've been looking around the web and I'm finding some answers... but not much has come up. I got a great deal on Office 2016 for Mac through my university, I then got a free copy of Windows 10 with it. I'm trying to dual boot Windows 10 and OS X on my 2010 MacBook. I know I can't use BootCamp and rEFIt is no longer supported. I downloaded rEFInd and it said that SIP was active, so it couldn't install. I found a guide online to disable it to get rEFInd to install, but when I typed the command in terminal, it said no such command existed. Does anyone have any information that could help me fix this issue and get my laptop dual-booting?
