-<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>
