Download a nightly build on OS X 10.11 El Capitan 2. Launch it Safari launches, but About > 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 bug 150029 comment 4 but thought it was worth its own report. 1133746 1 ap 2015-10-15 20:38:40 -0700 *** This bug has been marked as a duplicate of bug 149346 ***
