Posted this in thread: https://obsproject.com/forum/threads/obs-crashing-on-startup-on-high-sierra-10-13-6.116538/ but realized that is describing a crash on startup, whereas my OBS is crashing upon selecting source for NDI.

'I am having similar issues, but none of these fixes worked. Launching from terminal, installing NDI separately as well as with the package installer (even though I have High Sierra NOT Catalina), clearing profiles/scenes, giving OBS access to make changes in Preferences, etc. Here is my crash log: https://pastebin.com/ZhMvFbzQ

As soon as I try selecting a source for NDI is when it crashes immediately.

Any help would be extremely appreciated!

I have found the issue. If you go to to https://github.com/Palakis/obs-ndi/releases you will read "Download and run obs-ndi-4.7.1-macOS.pkg. This will install both the plugin and the NDI 4.0+ Runtime. On macOS Catalina (or if it doesn't install the NDI runtime automatically), you'll have to download and install the NDI runtime manually: download it here." - the runtime there is v. 4.5. We need v. 4.0. I had old version i've downloaded a few days ago on different mac. Now it works. I couldn't find how to share the file.

yurkomik, Any way you can load the file up to a google drive or a drop box? I keep crashing as soon as I select the mdi as a source as well.

When you say these current versions do you mean the 4.0 that they mention, the version we should be using?

Also, would I need to delete current version or how would that work?

Hi there,

i had the same Trouble with crashing OBS after selecting an NDI-Source.

My Solution:

Download the libNDI4 from here:
github.com

ofxNDI/libs/NDI/lib/osx/x64/libndi.4.dylib at master · nariakiiwatani/ofxNDI

NewTek NDI SDK Wrapper for openFrameworks. Contribute to nariakiiwatani/ofxNDI development by creating an account on GitHub.
github.com github.com

Go to Folder /usr/local/lib/

Delete the file libndi.4.dylib in this Folder.

Copy the downloaded libndi.4.dylib from Download-Folder into /usr/local/lib/

After restartingOBS or/and the Mac, everything works like a charm.

Greetings,
Martin

System:
iMac late 2013, 16 GB
Mac OS 10.14.6
OBS 24.0.6 (64bit)
obs-ndi 4.7.1

I report that Martin's method, i.e. replacing the libndi.4.dylib did the trick for me.
Everything seems to work fine (even though the Skype video is laggy and not smooth at all).

Add me to this list as well, I’ve been reading all sorts of articles for the last two hours and everything listed all of my Tech friends, this might seem obvious and trivial, but I can’t seem to find the folder to replace that file it doesn’t exist and I have installed three or four different versions of run time

Hi. It seems, your hidden folders are not visible.

Try this:

See hidden files on Mac via Finder
  1. In Finder, open up your Macintosh HD folder.
  2. Press Command+Shift+Dot.
  3. Your hidden files will become visible. Repeat step 2 to hide them again!

Hi. I'm not sure, but it seems, you don't have installed all packages, that are needed.
I had installed the libNDI_for_Mac.pkg from here:

github.com

Releases · DistroAV/DistroAV

DistroAV (formerly OBS-NDI): NDI integration for OBS Studio - DistroAV/DistroAV
github.com github.com

All My Steps:

Update OBS to 24.0.6
Download the obs-ndi-4.7.1-macOS.pkg and installed this.
Then i had downloaded the NDI-Runtime, mentioned in the Text on Palakis GitHub-Site:

After that I've downloaded the libNDI-Replacement from
github.com

ofxNDI/libs/NDI/lib/osx/x64/libndi.4.dylib at master · nariakiiwatani/ofxNDI

NewTek NDI SDK Wrapper for openFrameworks. Contribute to nariakiiwatani/ofxNDI development by creating an account on GitHub.
github.com github.com

I replaced the libndi.4.dylib in /usr/local/lib/ with the last download.

After these Steps, no crash, no error.

Hope, this helps.
