Install rEFInd on macOS High Sierra when System Integrity Protection (SIP) is enabled

# Download rEFInd from Sourceforge.net
$ curl -s -L http://sourceforge.net/projects/refind/files/0.11.2/refind-bin-0.11.2.zip -o refind.zip

# unpack downloaded file
$ unzip -q refind.zip

# Change directory
$ cd refind-bin-0.11.2

# Try installing rEFInd
$ sudo ./refind-install
ShimSource is none

**** 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/ericnoel/refind-bin-0.11.2
  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
