@Nicolas-Danet thanks! So many things I learnt in the last few hours... didn't even come to think something like configuring a network could affect pd loading or not

@Nicolas-Danet @whale-av

thank you SO much for the help!
I just managed to fix it!

Yesterday morning I needed to make a wifi network... (just to connect devices together, without any actual internet) and I couldn't find out how to do a network with a password so I followed this thread for advice:
https://apple.stackexchange.com/questions/182760/how-to-create-a-password-protected-ad-hoc-network-on-yosemite

it was the commands I entered to create this network what apparently led to trouble

sudo networksetup -createnetworkservice Loopback lo0
sudo networksetup -setmanual Loopback 172.20.42.42 255.255.255.255``````

deleting the network from my system preferences / network and restarting the computer fixed the issue.

@whale-av after some search... is it possible that wish was present in earlier versions of mac osx and not anymore with the current os?
I tried to make an empty folder named org.puredata.savedState inside my user/library/Saved Application State folder.. but still not able to enter those commands successfully

@whale-av thanks for your reply!
I tried to follow the instructions on the link that you mentioned but it turns out I don't have any file (or folder) called org.puredata (or pd, or something like that) on my /user/library/Saved Application State folder... so when I type those commands in the terminal it says that there is no such file or directory.

Regarding wish.app... I never had it installed (to my knowledge at least)

this is getting interesting! I get this message.

ERROR: failed to allocate port, exiting!```

I get exactly the same as you... so it must be something else

Thanks again!
It might be something regarding the hosts... I was trying to install a hack to remote control my Organelle via OSCproxy (and didn't get it to work before I got to this issue).

On your first link:
*If Pure Data is not launching on your computer, then check if your /private/etc/hosts file is configured correctly. *

Do you know in which folder I can find this?

Thanks!
Found them and deleted them... still to no avail.
Every time I try to open PD I see its icon appear briefly at the right side of the dock, ca 1 second, and then disappears for good.

Looking also for something going on on the activity monitor, but no processes appear either...

I don't know what to do!

Thanks so much for the help!

How can I delete the preferences? I can't remember where the preference file is.
It's the 64 bit version.
And I approved it manually at startup (right click, open in order to authorise it)

thanks for the reply!
if I type .app then I don't get any error messages, but nothing happens (pd still doesn't load)

I was wondering if anyone else has this issue. I double click on the app, nothing happens. I tried re-installing, and installing previous versions as well (0.49 as well as 0.48.1).

I also tried to open from the command line and this is what I got:

open -a Pd-0.49-1
Unable to find application named 'Pd-0.49-1'

I was using PD without any problems before that, I cannot remember how long ago it was that I opened it before, but it cannot be more than one week or so. I can't remember either wether my mac updated after I opened PD for the last time and wether that can have anything to do with it.

Thanks a lot for your asnwer, it solved my problem!

I'll have to change the path if I'm on another computer but it's perfectly doable.

Hello everybody,

I'm fairly new to PD and this is my first question in the forum. I hope somebody can help me, and sorry if this has been covered before (at least I haven't been able to find it).

I'm trying to send messages to the OSX terminal from PD; what I want to do is basically copying a certain file into a new path with a new name.

The text in my message is something like this:
cp ./jpeg/001.jpg ./output/NEW01.jpg

I have this connected to a shell object and I have a print STDOUT and print DONE objects to the left and right outlets just as I have seen on the PD help examples.

I checked my code and it and it works if I enter it directly on the Terminal, no problems here (being on the right directory in the first place of course).

I also tried to send a "cd" message to the shell object just before I send the other message, just in case PD wouldn't tell the Terminal wich folder we are in the first place.

The only noticeable difference is that in the console I see "DONE: 0" when I send the "cd" message and "DONE:1" when I send the "cp" message. but no files are copied in my system whatsoever.

What can I do?

I hope I made myself clear enough. Thanks in advance!
