It has been passed to me but my programming intray is still reasonably 
moderate
to heavy so have not got around to it.

That said I am aware that it does not like CPU's other than the basic and nor
for that matter platforms.

In my odd moments have been playing around to get it to work-ish on OSX 10.11 
El Capitain) but with minimal effect.

Had to go back to sorting out the code for ACAS for which I have a target for
end of the year.

How many CPU's are you running and with what architecture?
