Under System Preferences>Updates, Security Update 2016-001 10.11.6 shows as pending to install. Try to run update, but it never goes through the download/install process. It remains as pending.
When I check About this Mac, it shows that I am running OS X El Capitan, version 10.11.6.
How can I clear the updates so it no longer appears as pending (assuming that I am in fact running version 10.11.6)?
MacBook Air (13-inch Mid 2012), OS X El Capitan (10.11.6)
