The error I'm seeing (both master and latest alpha on pipeline) comes from:

System.Diagnostics.Debug.WriteLine ("You should be reading this. There should not be a \"Could not register the assembly 'Xamarin.Mac'\" error above this.");

You can remove every other line in that file and still hit that. And I can confirm that this line didn't cause issues in stable.

Ok, it was introduced somewhere in the range of:

Does not have bug - Version: 2.0.2.111
Has bug - 2.3.0.122

This appears to be a regression due to changes in mono. Moving the system folder's hash back to:

git checkout 2e6efb3 -- mcs/class/System

and rebuilding makes the issue go away. 

Going to talk to people to see what (if anything) we can do.

Wrote a test request for this to be made part of the manual test suite. It is still that this wasn't caught until now

https://trello.com/c/MLEnqetg/1782-xamarin-mac-cwl-debug-writeline-sanity-tests

Fixed in master / 4f2f6bb62eadc929c3ac9395e3ef40a8c08646e5

Requesting addition to C6 shortly.
