Unity 5.3.4f1 WebGL builds no longer works on Mac OSX... anyone have any ideas?

I delayed updating from earlier build of Unity 5 because I was working on a painstaking WebGL conversion from Web Player while writing new features for a medical simulator. All of a sudden my WebGL builds no longer work. Not the new ones, developer or build versions, nor my backups from previous versions of the simulator. So I updates to Unity 5.3.4f1. No changes. WebGL is completely dis-functional. Any help would be appreciated.

All these errors seem to be deriving from UnityLoader.js…
