Hi everyone,
I’m running OBS on a Mac Mini M2 (8 GB RAM), and I’m having a frustrating, inconsistent issue with audio–video sync drift when recording.
Setup:
Some days everything works flawlessly, even during 15-minute recordings. Other times, the video gradually lags behind the audio — it looks like the video slows down, while the audio keeps normal speed. Restarting the Mac or OBS sometimes helps, but not always. The desync can appear after one minute or not at all.
It feels random — no pattern I can find — and OBS never shows high CPU usage.
What I’ve tried:
Has anyone seen similar behavior or found reliable fixes for intermittent AV desync on Apple Silicon?
Thanks in advance for any insights.

What I’ve tried:
- Replacing the USB cable
- Updating firmware and OBSBOT Center
- Turning off all AI and gesture features
- Checking sync offset and encoder settings
- Disabling auto exposure and auto focus
