I will be reaching out to ProPresenter support as well, but wanted to ask if anyone else has experienced this issue.

I recently replaced the Mac at my church with a new M4 model. I reinstalled ProPresenter 7 and migrated the database. I rebuilt the two NDI outputs that I use with vMix. All of that works fine.

However, every Sunday morning I notice that the NDI inputs in vMix will not connect. I always make sure that ProPresenter is up and running before I open vMix. Fortunately, all I have to do is edit the input, click "Change", choose the NDI output again and save the changes to that input. This happens every time and I do not touch the NDI output settings in ProPresenter.

Has anyone experienced this? I set an IP reservation on the Mac so that it would keep the same IP, yet this is still happening. It's almost like ProPresenter is somehow sending these NDI outputs a different way every time it opens. I've even seen this happen if during service ProPresenter has to be closed and then re-opened. I have to edit the NDI inputs in vMix again, click change, and choose the correct output.

Thank you for your advice. I will continue to troubleshoot on my end as well.

Just a FYI: this issue did not happen with the old Mac before this one.

Yes it does. That's when I edit the input, click change, and choose the same NDI output (with the same name and number).

I have also reached out to Propresenter support to see what they say.

I have to click change on the input otherwise it's black. These are the only two NDI inputs I'm using.
