Camera freezing on OBS 32.0.2 (macOS Tahoe 26.1, M2, Cam Link 4K)

[Relsind]

Hi everyone,

I’ve been using OBS 32.0.1 on macOS Tahoe 26.0 with zero issues — perfect for podcast filming. After updating OBS to 32.0.2, my Sony ZV-1 → Elgato Cam Link 4K → M2 Mac (USB-C) setup began freezing within seconds of opening OBS. The preview and recording both freeze (like a still photo), though audio continues.

After updating macOS to Tahoe 26.1, the camera stayed active for almost 2 hours once, but now freezes again within minutes. The same setup worked flawlessly for weeks before the update, so something changed in 32.0.2 or its interaction with macOS.

What I’ve tried:

• Full clean uninstall / reinstall of OBS (deleted all support folders, receipts, and caches).
• Renderer set to OpenGL.
• Capture settings: Custom 1920×1080 @ 30 FPS, YUY2, buffering off, “Deactivate when not showing” on.
• Direct USB 3 connection (no hub, Belkin high-speed cable).
• Removed Camo, Insta360, and Teams.
• Reset macOS camera services:
  sudo killall VDCAssistant
  sudo killall AppleCameraAssistant
• Camera works fine in QuickTime (so freeze happens only in OBS).

Specs:
macOS 15.1 (Tahoe 26.1) | OBS 32.0.2 (Apple Silicon) | Sony ZV-1 | Elgato Cam Link 4K | Belkin USB-C 3.1 Cable

Request:
Has anyone seen video freezing with OBS 32.0.2 on macOS 26.1 using HDMI capture devices? Any stable workaround (YUY2 vs MJPEG, 1080p vs 4K, etc.)? Would installing OBS 32.1 RC1 help?

Any insights or confirmed workarounds would be hugely appreciated — this issue currently prevents me from recording my podcast.

Thanks a lot!
