I want to dual boot OSX and Linux on my Macbook Air, and to do this, I read that I need to install rEFind. If I try doing that I get a message in the terminal:
**** ALERT: SIP ENABLED! **** rEFInd cannot be installed because System Integrity Protection (SIP) seems to be enabled! You must install rEFInd from your Recovery installation or from another OS. To install from the Recovery system: 1. Reboot 2. Hold down Command+R as the chime sounds 3. When the OS has booted, select Utilities->Terminal 4. Change to this directory with the 'cd' command; it will probably be under /Volumes/Macintosh HD/Users/kramer65/Downloads/refind-bin-0.10.4 5. Re-run this script. If you believe SIP is NOT enabled, you may attempt an installation anyhow, but it may fail. For more on this subject, see http://www.rodsbooks.com/refind/sip.html Do you want to attempt installation (Y/N)?
So I followed the instructions. I rebooted into recovery and then tried to install rEFind again, but I get the same message.
When I try to install rEFind from recovery mode, can I safely ignore the message about SIP and type in
Y to continue installing rEFind? All tips are welcome!
