I tried to bring in a vMix Call guest tonight to do a "teaser" live video to promote a live chat on Monday. The guest was on a MacBook (not sure what version or what OS) using Safari. He entered his code and name on vMixcall.com and then saw (if I recall correctly what he described) a blue and green screen and I never got a notification that he connected. I then sent him a different code for vMix Call to try again, but he experienced the same thing, so I brought him in via Zoom (using desktop capture) instead. That worked fine but I would prefer to use vMix Call because I think the audio is less compressed.

Should I have had him try to use Chrome even though he was on a Mac?

Is it likely that his Safari browser wasn't up to date? Unfortunately, we didn't have time to troubleshoot tonight so I will do so before the show on Monday.

Any suggestions that might help beyond checking the browser version of Safari? Do vMix Calls via Chrome on MacBooks work? Are there some Firewall settings on a MacBook to check and/or turn off?

Thanks for any suggestions.

Thanks for your reply Guillaume. I had read the documentation but as I'm not a Mac user, I apparently misunderstood when I read "in Safari on iOS" and thought that all Macs use iOS as the operating system. I didn't see anything in the Knowledge Base on this, and when I Googled using vMix Call and Safari, I read the thread in this User Group. I find that sometimes I don't know the right questions to ask, and thus end up searching with the wrong questions when searching. As a result, I've found that asking questions in this group has been very helpful because users can point out the right questions to ask/consider.

I do appreciate your recommendation to test, test, test.

By the way, my guest was someone I know and was coming in via Mac (he's the only one I know on a Mac so I guess this was my first "test" with a Mac) but he was pressed for time. Fortunately, given that I had a Plan B (Zoom/Desktop Capture) that worked fine, it was a success.

I also appreciate anyone else's suggestions/input relative to the questions I asked in my post.

Safari will work with vMixCall.
The version of Safari, at least in my direct testing this morning, is 11.1. The system it was tested with is an iMac, running Sierra (10.12.6) - (not High Sierra).

I suspect that the problem experienced had to do with the browser not being updated.

If need be, I'd be happy to conduct a quick test with you, allowing you to confirm your system configuration and verify my results.

Incidentally, WebRTC support was added to Safari starting with version 11.

The latest version of Chrome will work fine on a Mac, when using vMix.
The main thing to remember is that the caller must give permissions to access the camera and microphone.

Of course, it should go without saying, for best results always connect via hard-wire and not wireless.
