Bug Report Syphon wont work on Mojave

Okay, two separate things.

One, Apple implemented a security feature on MacOS called SIP that in its latest version, as part of Mojave, disables things Syphon needs to work. The workaround is to disable SIP:

Secondly, Syphon (and OBS) depend on the OpenGL framework, which Apple appears to be in the process of deprecating in favor of their own framework, Metal. Apps that use the Metal framework cannot be captured by Syphon at all.

Your options basically are:

* Window or Display capture instead
* Disable SIP and reboot to use Syphon if you are capturing an OpenGL application
* Downgrade to High Sierra where Syphon still works without disabling SIP

I’m not a developer— not on OBS or on anything else— so I am not qualified to say so either by specific or general knowledge.

If, as a layperson and a Mac user, I had to guess, I would say no, unless either Apple makes a positive effort to enable it, or the OBS project makes a considerable investment of effort to enable a method of capture compatible with Metal; and in all likelihood it would not actually come to pass unless both these things happen.

This is unfortunately one of the results of Apple abandoning an open standard (OpenGL) and replacing it with their own proprietary API.

I wish there was better news forthcoming, either from Apple or OBS, but in the absence of new information or announcements, I do think that users who need to use OBS and have Syphon functionality should remain with High Sierra.

Question / Help Any capture device on Mac that does 1080p/60fps AND supports OBS Syphon?

For the life of me I can’t find a capture device that will work comfortably and I’m hoping that this forum may have the answer I’m looking for.

I had seen that Blackmagic design devices are supported by OBS so I picked up an UltraStudio Express thunderbolt capture device — and was surprised to find that it only supports 1080p/30fps, not 60. So that got returned.

So then I went with an AVerMedia Live Gamer Extreme which had the right feature set — only to find that it doesn’t have any Mac drivers at all and there are no plans to add any (according to their technical support). So that got returned, too.

I currently own an Elgato HD60 which captures well, but obviously hasn’t provided drivers that allow OBS to integrate Syphon support — and that’s a bummer. At least we can go the Display Capture route, but I was hoping to find a more elegant solution.

Context: I do have a gaming PC but I do my editing in FCPX on a Mac, so I use the HDMI out to an Elgato and capture directly to the Mac. I was hoping I could keep this setup intact and let the Mac do the heavy stream processing to free up resources on the gaming PC, but that’s proving trickier than I’d expected.

Am I out of luck for the time being, relegated to Display Capture for streaming? Or does anyone know of any capture device that supports 1080p/60fps AND device support with OBS, or at that least works with Syphon Inject?

Question / Help Problems with Syphon Client (SIP disabled)

I have a problem with the obs program.

I have imac with the Catalina operating system and when I want to capture a game (minecraft) I am using the Syphon Client Source but i can´t click in the buttom.

I have disabled SIP but I still cannot access.

I thought that setting the SIP disabled would be solved

I don’t believe so. Support for the capture method used by SyphonInject is no longer available in Mojave and above. It is not being prevented by SIP. Disabling SIP does not recover this functionality.

Running with SIP disabled in Mojave, the only app I’ve successfully been able to capture with Syphon is OBS itself, and I think even that works without disabling SIP— but disabling SIP does not allow other apps to be injected.

Thanks for the answers, Narcogen

Although Narcogen said «Syphon does not function in Mojave and above.», I managed to install syphonclient in Catalina but i have some problems.

First of all I would like to say that I have a friend that has my same configuration and it works for him.

How I installed the program?

1. Install OBS Studio
2. Disabled SIP in the S.O. Catalina
3. Install Syphonclient 1.2

When I want to capture through Syphonclient I can inject without problem but when but I see the screen resized.

Can anybody help me?

Another new member here with the exact same problem as @nukero.

I’ve tried transforming the capture area in every way that I can think of but still SyphonInject only captures the bottom left. Any help would be really appreciated.

How do you reduce the source?¿

Hi, sorry for the slow response. Here’s how I did it:

Scaled down and blurry solution (all in OBS)
1. Add a video source
2. Add a Syphon Client
3. Move the Syphon Client window to the upper right corner of your canvas and scale it down a bit
4. Scale down the video source window and move it to the lower left part of the canvas. You can now scale this up or down and see the result instantly in your Syphon Client window (in the upper right).
5. If you want to you can add filters to the video source to try to compensate for the blur, such as adding sharpness and using some color correction.
6. If you get grey borders on the sides of the video, you can solve this by reducing the size of the OBS window so that the video covers as much of the space as possible.

Hope this helps a bit. Personally, my main goal was to get the video into CamTwist, so I have decided to not use SyphonInject for now and instead use the Desktop+ feature in CamTwist to capture the entire OBS window instead (which only works if you have a second screen).

OBS on Apple Silicon

I’d be surprised if emulated performance were good enough, so it probably won’t be usable until there’s a native build. I also have no idea whether there have been any official discussions about that (and indeed, I was actually looking for the answer to that question when I stumbled onto this thread).

I’m going to give a gut feeling based on my limited knowledge of the code base and limited understanding of what Apple is shipping. Other folks can feel free to correct me if I’m wrong.

Given that OBS runs on ARM hardware already (folks have run it on Windows for ARM64 and on RPi), I would not expect any huge technical hurdles. The main pain point will probably be getting official macos-arm64 builds of the libraries that OBS depends on, then convincing somebody who owns the hardware to do the work to build it and test it.

Thankfully, Apple did (reportedly) make native OpenGL library support available on ARM (at least for now), so there’s one huge bullet dodged. And folks got Qt building on Mac ARM silicon way back in July, which is the one dependency that I was most worried about, given how much more tightly it integrates with the OS than low-level bits like ffmpeg, x264, etc. The other dependencies will probably «just work».

One other likely headache is that (unless NewTek has released a new drop of their SDK in the last couple of weeks) the NDI library and runtime that a large number of OBS users depend on isn’t available for ARM-based macOS yet. I don’t know if linking against the static iOS binary is feasible (with some linker path rewriting) or not; it depends on whether that library links against any symbols that aren’t available on macOS. I’ll drop NewTek a line and see if they have any news to share on that front.

But mainly, I suspect it’s just a matter of somebody having the right hardware and spending whatever time it takes to fix whatever any of the random build issues that invariably come up when you port a large piece of software to a new architecture/platform combination, and maybe adding a build script to lipo the x86 and arm64 app bundles together so that they can ship a single app that runs on both architectures.

Hi, I am testing this now on the M1 MacBook Air.

Works perfectly, in fact it is much better than my 10th gen intel MacBook Pro https://twitter.com/a_mrbenmitchell/status/1329795992829513728?s=21
