Seems incompatible with Resolve 20 and higher with Mac #9
Description
Brushes Fuses Library Modules Templates
Seems incompatible with Resolve 20 and higher. I tried multiple times with Mac M2. The open Rembg button in Fusion does not work. And looked up an answer.
Notice what’s missing:
No Python/ folder
No bin/python3.x
No embedded pip
This confirms:
DaVinci Resolve 20.x Studio on macOS no longer ships Fusion’s embedded Python runtime
This is a major change in Resolve 20 (undocumented and confusing).
🚨 Why Rembg.fuse will NEVER open on your system (as-is)
Rembg.fuse:
Was written for Resolve 18.x / early 19.x
Assumes:
Fusion/Python/bin/python3.x
In Resolve 20, that runtime does not exist
When the Fuse calls Python → silent failure
So:
Plugin loads ✔️
Button exists ✔️
Clicking does nothing ❌ (no Python backend)
This is not fixable by reinstalling Resolve
This is not fixable by installing Python 3.14
✅ The Truth (no fluff)
On DaVinci Resolve 20.x Studio + Apple Silicon:
Rembg.fuse is effectively broken
Unless the Fuse is rewritten to:
Use external Python
Or Blackmagic restores embedded Fusion Python
🟢 What DOES work (recommended alternatives)
✅ Option 1 — Magic Mask (best choice for you)
Since you’re on Studio + M2 Ultra:
GPU-native
Faster than Rembg
Stable
Supported
People / Object Magic Mask
→ Pipe into Fusion if needed
✅ Option 2 — Fusion-native workflow (no AI)
If you want control:
Delta Keyer
Clean Plate
Surface Tracker (Resolve 20)
Rock-solid, no breakage.
If you must use Rembg:
Run rembg outside Resolve (CLI or GUI)
Export alpha PNG or ProRes 4444
Bring back into Resolve
This works because:
macOS Python is fine
Resolve 20 just can’t call it internally
🧠 Why you’re seeing outdated tutorials
Most Rembg.fuse tutorials:
Were made on Resolve 18
On Windows
Or Intel macs
They no longer apply to:
Resolve 20
Apple Silicon
Studio builds without embedded Python
Bottom line:
❌ You are NOT misinstalling anything
❌ Python 3.14 doesn’t help
❌ Reinstalling Resolve won’t fix it
✔️ Rembg.fuse is incompatible with Resolve 20 macOS
