I have upgraded my Mac to OS X El Capitan (version 10.11.4) and updated Xcode (version 7.3 (7D175)). I'm working on Xamarin (version 5.10.3 (build 27)). I get all iOS Simulator components (from Xcode Preferences/Components), versions 8.1, 8.2, 8.3, 8.4, 9.0, 9.1 and 9.2, no version 9.3 available..
After all upgrades and a restart I open my project in Xamarin and launch it and an error message raise to say that the iOS Simulator cannot start. I tried to create a new project on Xcode (to see if it was related to Xamarin), tried to launch it and the same issue occurs.
This is the crash report:

I don't understand why the /usr/local/lib/libwep library is not loading.
There is no explicit message or information to understand the issue and try to fix it. I do not find a lot help on similar issues.
I tried this solution, but it just removed the iOS Simulator components that I just download with Xcode.
I need help, if you have any ideas, as I can't debug anymore until this simulator will start.
The issue is caused by your use of WebSense. This software injects a library (usr/local/lib/libwep) into every process, and that practice is not valid for processes utilizing library validation for increased security. Simulator.app is one such process that is making use of library validation.
You need to reach out to WebSense for a compatible update to their software.
