Well thanks for the help guys. Let me answer these questions here...
It (osx) originally gave me this message that because PD was created on a PowerPC PD was no longer supported. I haven't seen that message since I uninstalled several of the most updated version of PD.
I told you that it wouldn't create a new file, but actually it just won't do mostly anything. I can turn on/off the DSP, everything else is a no go --can't even type in the help menu.
I have uninstalled and reinstalled PD extended for MAC 0.43.4 several times now and each time I can get it to initiate but then not do anything like I said. So... my history with PD is as follows: downloaded PD vanilla, then downloaded Extended and extended worked for a while. I think the problem started when I upgraded to El Capitan (mac's newest OS). The patches I created in extended just stopped putting out audio. So I uninstalled and reinstalled (PowerPC message hit me) and now it's the same problem. I was working on a project and completed it with PD vanilla (which seems to work fine for me)
No messages in the terminal window.
I used to get messages asking me whether or not to trust this application as it was downloaded from the internet. But always answered yes.

Yeah I did this many times now. When the new version (Mac OSX, Intel) is opened it won't create a new file when I click New.

Has anyone figured out why PD extended is no longer working on Mac OSX? It gives me some message that programs created on a PowerPC are no longer supported.

Yeah, sry, I guess I should have explained it better. If you hit the toggle above the color you can see the color that is playing and then hit the toggle to the left of that to play the piece.

Hello PD World. I am in possession of a Yaacov Agam painting. One day I said to myself, this could be musical notation. Why not? The colors have been converted to frequencies, white=noise, black=nothing, the shapes are adsr envelopes, and the length of each color in mm has been converted to ms. I'd love it if I could get some feedback on this, and if anyone wanted to try a different way I'd also be super interested in seeing/hearing it. acousmatized agam lw edit.pd

I love this!
