Q: Security Update 2016-002 could not be verified
I am running Yosemite 10.10.5. Was prompted this afternoon to install system update "Security Update 2016-002". It did a 461 MB download and then forced a restart. After restart, the update proceeded for a few seconds and then unexpectedly terminated with a pop up that said the downloaded update could not be verified. Here's the error prompt: "Security Update 2016-002 could not be verified. It may have been corrupted or tampered with during downloading. Click Update to download and check the update again". I did this three times. The update failed each time, same reason in the error message. Did this update go through QA? Any thoughts on this?

Try downloading the installer file directly from Apple and installing it from the Desktop.
