<p>Note the line that reads "System Integrity Protection is disabled (0x77)" (highlighted in this screen shot). This line will be updated whenever you use the CSR rotation tool, so if you've specified a large number of values and have forgotten where you are in your rotation, you can use the About screen to figure it out.</p>
-<p>Both the summary on the About page and the CSR rotation tool depend on the presence of the <tt>csr-active-config</tt> NVRAM variable, which is where this information is stored. Thus, these features will not be present on older Macs that have not seen the presence of an OS X version that sets this variable. Likewise, you probably won't see the SIP summary in About or be able to set these values via <tt>csr_rotate</tt> and <tt>csr_values</tt> on a UEFI-based PC. (You could always create the variable on such a system in some other way, in which case rEFInd would let you adjust it, but it would have no effect on any OS except OS X.)</p>
+<p>If your Mac doesn't yet run OS X 10.11, rEFInd claims that SIP is enabled in the "About" screen. If you set the <tt>showtools</tt> and <tt>csr_values</tt> options as described earlier, you can adjust the SIP settings on such a Mac, but this will have no effect because neither pre-10.11 version of OS X nor any other OS honors these settings. On UEFI-based PCs, rEFInd won't display SIP status <i>unless</i> you store the <tt>csr-active-config</tt> NVRAM variable in some way. If you do, rEFInd will enable you to adjust it, but it won't have any effect on the OSes most commonly found on UEFI-based PCs.</p>
<p>I provide these features in rEFInd as a convenience for developers and other advanced users who have a need to adjust their SIP settings. Using rEFInd for this purpose is much faster than booting into the OS X Recovery system to make these adjustments. I discourage others from playing with these settings, since changing them inappropriately could cause problems; that's why they're not enabled by default.</p>
