security update 2019-004

My MacBook Pro no longer is working properly after this update. It continues to restart on its own and gives me a prompt about Chrome not shutting down properly.

MacBook Pro 15", macOS 10.13

boot into Safe mode, and then install the update

This will not load any 3rd party additions, it will load some more conservative Apple drivers (may cause screen flicker), and it will clear some kernel caches (a cache is saved data in a form that can speed up a program, but is totally redundant to the original source, and thus can be safely cleared).  Booting into Safe mode is just an experiment, but can frequently eliminate any 3rd party interference, or a cached item out-of-sync with the world.  (Verify Safe mode via Applications -> Utilities -> System Information -> Software -> Boot Mode -> Safe vs Normal)
