        <pre>To reproduce:

1. Download a nightly build on OS X 10.11 El Capitan
2. Launch it

Safari launches, but About &gt; Safari doesn't show the WebKit revision number and as far as I can tell the system WebKit is being used rather than the nightly WebKit.

Could this be due to System Integrity Protection?

I mentioned this in <a class="bz_bug_link 
          bz_status_RESOLVED  bz_closed"
   title="RESOLVED WORKSFORME - Incorrect initial rendering with Tab characters and white-space:pre/padding-left"
