Although I have seen situations using a firewire camera where a GEM patch suddenly

...yep, the only problem I've seen that isn't solved by unplugging
and replugging the camera is the well known problem with
[pdp_ieee1394], and this is due to copy/paste misuse of the Quicktime
SequenceGrabber API (you can't run SGIdle() in a seperate thread)...
„THERE IS ALSO AN EXPERIMENTAL PORT TO MAC-OSX"
does not quite sound like what you described. actually it scared
me from using Gem quite a bit, until franz of the sat told me that it's
not true.It's about as experimental as the rest of Pd, which does scare off a few folks. I often hear that because there is no company peddling Pd, it is 'unsupported' and 'unstable'. Oh well.
Someone should update that IEM page and remove that line. The link to my page can probably go since it is pretty out of date as well.
...yep, that page hasn't been updated in at least 2 years: going
further than what chris says, I'd add that gem on osx is more stable
than pd's audio system on osx! As usual, this comes from the fact
that the osx developers' interests tend more to using pd as a
graphics rather than an audio instrument...audio is actually on my
new year's to-do list, so we'll see...
...as a sidenote, despite some osx tcl/tk improvements, there's still
lots of room to go: I mean, we are emulating XWindows calls on a
wholly different display system...with that in mind, I'd like to
remind everyone that there's no real reason to use the aqua tcl/tk:
pd works a bit better when using the x11 tcl/tk (certainly looks more
like the linux version)...and the good part is that even doing this,
the GEM & gridflow windows still output to native osx opengl (pdp/3dp
coming soon!)
