Hi Roger.

Fine. Unfortunately this is a difficult issue to solve. QEMU (and maybe Cocoa) has changed his policy about the GUI in OSX. It's a problem I don't see because I am stuck with El Capitan 10.11. The IOEMU window runs in another thread and so a crash happens.

Anyway, if it is pleasant for you, you have a decent toolchain setup now. I will try to solve the QEMU issue, just don't hold your breath.

Maybe next days I will release a QEMU version for you without the IOEMU window in order to check if it's running Ada code correctly, by using the serialport terminals, waiting for a definitive solution.

I'll come back ASAP.
