Tahoe and OBS potential issues

Hi guys,


I have been using OBS (32.0.1 until Monday 10 November 2025) on Tahoe 26.0 and it has been a perfect combination for videos etc. At the end of Monday I updated OBS to 32.0.2 and it started freezing my video during recording, actually even without pushing the record button, just within 10 seconds of opening up OBS and the video would immediately freeze. I tried loads of workarounds and suggestions by AI to no avail. Last night I updated my Mac to Tahoe to 26.1 and OBS took 2 hours to freeze my video, meaning, it improved a lot but the problem remains.


Does anyone here have a tip or workaround I could put in place? The freezing problem now happens more regularly than the initial 2 hours it took to freeze. Just now I restarted OBS and it took just a few minutes to freeze the video. So, it is impossible for me to shoot my podcast at the moment via OBS.


Any tips or help would be very much appreciated. Everything else with Tahoe 26 seems okay so far.


Thanks

MacBook Pro 14″, macOS 26.1

I'd do two quick things — short and to the point:

  1. Switch the capture to MJPEG 1080p, turn buffering on and uncheck “Deactivate when not showing.” Less USB throughput and the device stays active — that’s stopped freezes for me before.
  2. If that fails, roll back to OBS 32.0.1 or try the 32.1 RC. It's the easiest way to get back to a working setup or test a build that might already fix the bug.

there are loads of reports on the OBS forum by apple users that, since Apple updated its OS, OBS became unusable or it runs with issues. It must be, at least in part, an Apple problem since people reported no problems on Windows laptops.

Any time there are two different opinions on a given topic, I've found a neat trick that's guaranteed to reveal the appropriate course of action.


You're claiming that this must be, at least in part, an Apple problem. OK. I accept your claim completely. Apple changed something and now OBS has problems.


So what do you do now? What are your options?

1) Roll back to Sequoia or earlier

2) Wait for Apple to fix the bug

3) Get OBS to work around the Apple bug somehow


Let's analyze each option...


1) Always a pain, but if you have good backups (or even better, all your ephemeral data in iCloud), a guaranteed fix.

2) Not gonna happen. Not in this universe at least.

3) This may be possible. Don't know anything about OBS or the problem.


Yes, yes, yes. I already know what you're thinking. But I've literally seen this too many times to count.

No. #2 is not a viable option. It will not happen. Give it up. End Of Story.


While you're waiting on that reinstallation in #1, consider your next steps. If this is software that you really depend on, you're going to have to take a more pragmatic approach. Don't upgrade the OS until everyone else who uses OBS says it's great. If you want to be a "that person" that always has the leading edge on everything, but you also have work to do, consider the purchase a new computer just for running new OS updates. This is what I do. I'm a developer so this is daily life for me. I run Sequoia because Apple won't let me submit apps with anything earlier. I ran the Tahoe beta on my test machine and now I run the released versions of Tahoe on the test machine.


You should also put some confidence in the OBS developers. If you haven't experienced this kind of problem until Tahoe, then OBS sounds like rock-solid software. That's truly impressive. But Apple beats us all down eventually. Are the OBS devs going to pack in and go home, or are they going to put more effort into Apple development? Tahoe has been available to developers since early June. I checked the GitHub site, and there doesn't seem to be much macOS activity there. Rather than complain in the forums, start posting issues on the GitHub site. Even if you're convinced it's an Apple bug, it's still worthwhile to document the bug, and not with Apple. Remember point #2. Apple may have broken it. But now it's OBS's responsibility to fix it. You can help with that.

Just adding more detail to help:


Title: macOS (Tahoe 26.1) + OBS 32.0.2 + Cam Link 4K → camera freezes (worked on 32.0.1)


Setup


  • Mac: Apple Silicon M2
  • macOS: 15.1 “Tahoe” (26.1) (was 26.0 before)
  • OBS: 32.0.2 (32.0.1 was stable)
  • Camera chain: Sony ZV-1 → Elgato Cam Link 4K → USB-C (Belkin high-speed), plugged directly into the Mac (no hub)
  • Renderer: OpenGL
  • Capture settings typically used: 4K30; also tested 1080p30; YUY2; buffering off

Symptom

  • On 32.0.2 the video preview freezes (looks like a still photo).
  • On macOS 26.0 it froze within ~10 seconds of opening OBS.
  • After updating to 26.1, it once ran ~2 hours before freezing, but now it freezes again within minutes of launch/recording. Audio continues; only the video capture hangs.

Known-good baseline

  • OBS 32.0.1 + macOS 26.0 was perfect for weeks (many recordings, no issues).

What I’ve tried

  • Full clean reinstall(s) of OBS (including deleting ~/Library/Application Support/obs-studio, prefs, caches).
  • Disabled Automatically check for updates.
  • Removed other camera apps (Camo, Insta360, Teams), and quit all camera-using apps.
  • Renderer = OpenGL (never Metal).
  • Added camera as Video Capture Device (Legacy).
  • Forced Custom: 1920×1080 @ 30fps, YUY2, Buffering off, Deactivate when not showing on.
  • USB direct to Mac; verified USB 3.x link; tried different port/cable.
  • macOS camera service reset:
  • sudo killall VDCAssistant
  • sudo killall AppleCameraAssistant
  • Tested camera in QuickTime > New Movie Recording (generally OK there).
  • Log showing timeouts/hangs (from earlier session): https://obsproject.com/logs/yrndhlLSa7NBp84N

Request

  • Is there a known AVFoundation / UVC regression with OBS 32.0.2 on Tahoe 26.1 affecting HDMI capture (Cam Link 4K)?
  • Any recommended capture format or device setting (YUY2 vs MJPEG, 1080p30 vs 4K30) that’s most stable right now?
  • Would you advise installing 32.1 RC on macOS 26.1 for this issue? If so, any specific flags/settings to use?
  • Happy to provide fresh logs—tell me which diagnostics you want (recording vs idle, with timestamps, etc.).

Thanks a ton for any pointers—this is blocking podcast production, so any stable workaround or known-good combo would be greatly appreciated. 🙏
