Yves,

  

but, by the way, i received some very unfriendly mails
from MAC users ( consumers ) UNHAPPY with their product
as if they were writing to a company dealer,
      

It's true that there can be some culture shock between the Pd (do-it-
yourselfers) and the Mac (click, and it just works) communities. I do
hope you're not discouraged by those folks, but Pat also rightly brings
up the idea of pent-up demand and excitement.

Anyway, some hints to potential users, and comments to Sevy:

If you get an error message on startup about pdp_text not finding a
default font, try this:

 sudo cp pdp_pidip_osx/fonts/helmetr.ttf /usr/X11R6/lib/X11/fonts/TTF/

  

The nifty pdp_ieee1394 object looks like it isn't re-entrant yet (i.e.,
you can't create a second pdp_ieee1394 object, even in another patch
after one has been destroyed). This might show up with a bunch of lines
like "pdp_ieee1394: SGIdle failed." or "pdp_ieee1394: grabber
initialization failed". If you run into this, I think the only way to fix
it is to close pd and restart. It's not pretty, but from the commented-
out code, it seems like there's some trouble with the implementation.

It's most irritating when trying out all the nifty sample patches!

Can the Gem/OSX folks offer any insight into this?
