[PD] Building externals on OSX

The best approach might be to just support all proprietary OSes by
compiling Pd to emscripten and building an interface using one of
the various html5canvas/svg javascript libraries.  Then, when the
EME DRM hooks get forced into html5, use them to require a
pay-walled subscription infrastructure on anyone not using
a free software operating system.

One could essentially do it by packaging some DRM blobs for
Debian non-free and various other distros (Ubuntu PPAs,
etc.).  Then, like Apple, every time Pd gets updated,
change the API for the blob.  Free software OS users would
automatically get it with their system update (or by downloading
the newest Pd binary)-- when they want to run Pd through the browser
the EME infrastructure sends the blob a puzzle and the blob sends
back the answer that lets users run Pd-on-the-web without any limits
or pay-wall.  (Either once per session or sending it periodically.)

Of course you'd get some perturbed Mac devs who could just try to
remove the DRM hooks, but that's the reason to get a few extremely
broad patents on some of the fundamental aspects of the way the
message dispatcher speaks to the gui (or something else
similarly trivial) and just threaten anyone who tries to remove the
arbitrary restrictions with lawsuits.

Besides, you'd only charge an _extremely_ modest fee per month
in order to real-time DSP in the cloud on proprietary OS.  After all
it costs money to develop software, and if those users want
unrestricted access and lower latency they can install a free
software OS and get it for _free_.

I wouldn't want to go through the trouble of doing this, but it's a fun
thought experiment to twist idiotic technologies
and counterproductive business models in the interest of freedom
and sharing.

I think Apple hardware has a MTBF of about 3 years; their business model 
relies on customers junking the old model at ever increasing rates and 
buying the new one. The old one after all never quite worked properly 
because they sold it before it was ready. I have a bunch of old Macs 
around here that mostly won't start up anymore. Usually the hard drive 
or the power supply fails.
Good luck replacing either.
I'm pissed because I've lost a lot of my work that way and with the 
constant incompatibility from one version of MacOS to the next not to 
mention the uninteroperability with any other OS.
So anyway PPC is obsolete and such a machine trying to run a new version 
of any software would probably choke on it anyway.
And OSX on PPC was really slow, system9 worked better.
I think the best thing is to not upgrade at all and try to keep it 
running the old software while not stressing the hardware in any way.
