I am also having this problem. I cannot speak for others, but I checked the OM 6.10.1/resources/lib/mac/ folder and both files are there. Don’t know if it helps, but it doesn’t seem to be missing files, at least those.
ok, I think I got something : the patches I provided probably work for people who upgraded to Sierra with an existing OM installed.
It seems Sierra has new restriction regarding security which now prevents OM to access newly installed libraries (such as the ones that are installed in its own package!). I have been able to reproduce the crashes (I think) by cleaning up my previous OM and just reinstalling the exact same version.
So : people upgrading to Sierra : keep your existing OM version + the four patch files. Do not try to re-install OM. 
I’ll keep you posted with more info.
Yes LibAudioStream.framework and SDIF.framework are correctly present in OM 6.10.1/resources/lib/mac/ , but OM claims they are not.
There’s probably something here related with the new security features of OSX
Basically applications are supposed to behave more ad more like Apps on your iPhone : not interact with external files and resources (or with the file system in general). So it is possible that the program is just not allowed to see them.
Hi there.
Some news : It seems that one of the issues we are facing with Sierra indeed has to do with these new security stuff, and in particular with downloading the app through the internet (even if it is packed in a zip or dmg).
A flagged (“unidentified”) download will not be able to access its own libs and resources.
I think some problems can therefore be “solved” (bypassed) for instance if you don’t download OM but sync it using a cloud client.
I have created this temporary DropBox link to test the hypothesis :
=> do NOT download the file here, but choose the “Add to my DropBox” option and get OM imported directly in the DropBox floder of your computer (you need to have the DropBox Desktop client isntalled as well).
(Let me know if some people here are not using DropBox : I can also try to do it with Google Drive.)
Please let me know if it works.
Note : tha app on this download has been compiled on Sierra with the required patches that I provided earlier on this thread : do not copy them again in OM 6.11.
This application release also includes a brand new audio support and library which has not been tested yet. Please try and report issues.
Jean,
Thank you for your work on this. I don’t have dropbox, but I do have google drive and would like to try this. Let me know if you need any more information from me. You might want to wait to see if the dropbox hypothesis works, though, since I doubt it will work with Google if it doesn’t with dropbox.
Thanks,
Tim
It worked for me, thank you very much !
I quickly made a Google Drive link: https://drive.google.com/file/d/0ByElw61bzz1aLTFxSFZ0dXVoODA/view?usp=sharing
ça a marché ici aussi, Jean! Merci!
I opened OM in my google drive from the link given, but it gives me an error message just saying that OM 6.11 can’t be opened. It seemed to extract OK, but I might delete and try again later if I have time.
Tim
It works, thank you.
Needed to install SimpleSynth for MIDI playback.
This is probably a dumb question, but I successfully got OM to work from my google drive on my iMac, but if I try to access it on my macbook, it gives me an error that just says it can’t run it. I waited for my google drive to sync. Is this normal behavior? Do I need to do something else? Or will I only be able to run it from one machine?
Tim
Hi. I guess you’d better not run it from your google drive.
Just copy it somewhere else on you computer.
Thanks for the temporary fix - it works wonderfully!
Nigel
Many thanks for this Jean.
It installed via Dropbox and works.
All best wishes
Sohrab
Dear Jean, after using the temporary Dropbox solution, I am getting two errors:
[1] Trying to open the program:
SDIF Library Error
[2] Trying to create workspace:
ERROR: Foreign function juce::|%cffi-foreign-function/OPENAUDIOPLAYER| trying to call to unresolved external function “OpenAudioPlayer”.
Thanks
Hi everyone.
The DropBox and Google Drive links are deactivated: I now suggest you to download and test the updated OM 6.11 DMG that I temporarily posted here : https://forge.ircam.fr/p/OM/downloads/604/
This release candidate follows the security/packaging prescriptions of macOS Sierra, includes the Lisp/Sierra patches and recompiled audio and SDIF libraries.
Please report back (problems or success). Thanks.
Jean
I’m pleased to report: success! No problems whatsoever so far.
Thanks!
Best,
Nigel
Hi Jean,
It seems to work fine for me, I just noticed one odd thing :
When I go to preferences, in the MIDI tab, I cannot change the MIDI setup, it says “setup unavailable” (see screenshot).
I have the same error with the beta version that you sent earlier.
Is it related to the current problem or should I start a new thread ?
Thanks !
mmhh. I’ve seen this before…
I think if you do a Restore / Apply you might get your MIDI setup back
