+<h4>Disabling SIP with rEFInd</h4>
+</a>
+
+<p>As described later on this page, rEFInd provides SIP control features, but they're disabled by default—except on the USB flash drive and CD-R images available from the <a href="http://www.rodsbooks.com/refind/getting.html">rEFInd downloads page.</a> On these images, the SIP control features are enabled, and can toggle between the two main modes you can set via <tt class="userinput">csrutil enable</tt> and <tt class="userinput">csrutil disable</tt> in the Recovery HD system. Thus, to disable SIP to install rEFInd, you can:</p>
+
+<ol>
+
+<li>Download the USB flash drive or CD-R version of rEFInd, as suitable for your computer.</li>
+
+<li>Prepare a boot medium. With the CD-R image, you can use your favorite disc-burning software. With the USB flash drive image, you can use <tt>dd</tt> to copy the image to a blank disk, as in <tt class="userinput">dd if=refind-flashdrive-0.10.0.img of=/dev/disk3</tt> to write the image to <tt>/dev/disk3</tt>. <b>Any existing data on the target disk will be destroyed!</b> For this reason, it's <b><i>imperative</i></b> that you specify the correct target (<tt>of=</tt>) disk; if you accidentally point this command to your regular hard disk, recovery will be difficult!</li>
+
+<li>Reboot and hold down the Option (or Alt) key to see the Mac's built-in boot manager.</li>
+
+<li>Select your external boot medium to boot to rEFInd.</li>
+
+<li>Use the SIP "shield" icon on the second row to toggle between SIP setting, as described in more detail in <a href="#refind_manage">Using rEFInd to Manage SIP.</a></li>
+
+</ol>
+
+<p>Once you install rEFInd, you can leave SIP enabled, adjust its SIP settings to enable the features from rEFInd and disable it from within your regular rEFInd, or boot again from your external rEFInd to disable SIP.</p>
+
+<p>This procedure has the advantage of being a bit quicker than using the Recovery HD—at least, if you've already got rEFInd 0.10.0 or later on an external medium. It will also work if your Recovery HD installation is missing or broken. On the other hand, it's probably easier to boot to the Recovery HD once or twice than to download and prepare a rEFInd boot medium. Also, some Macs are a little flaky when it comes to booting from external media, so you may have trouble booting in this way. Finally, if you don't already have rEFInd on an external medium and if you don't have an optical drive, writing a USB flash drive with <tt>dd</tt> carries a small risk of accidentally trashing your hard disk, particularly if you're unfamiliar with disk devices and <tt>dd</tt>.</p>
