Prefer no installer on Windows? Portable .zip (413 MB). Intel Macs are not supported yet. Release notes
The Mac app isn’t code-signed yet.
The Windows installer is signed, and Windows shows the publisher as Samuel Price. The Mac build isn’t signed yet, so macOS asks you to confirm the first launch. How to open it · Check your download
First launch
Why your computer warns you, and how to open Loopcut
macOS and Windows look for a developer signature before they open an app from the internet. Loopcut’s Windows installer carries one; the Mac app doesn’t yet, so macOS can’t tell who published it and asks you to decide. That’s all the warning means; it isn’t a problem found in the file. Windows can still ask once while our new signature builds a reputation. You can read every line of the source and check your download against the checksum we published.
macOS · 15 Sequoia and later
- 01Open the .dmg, drag Loopcut into Applications, then open Loopcut from Applications.
- 02macOS says Apple could not verify “Loopcut” is free of malware. Click Done.
- 03Open System Settings › Privacy & Security and scroll down to Security. Next to “Loopcut” was blocked, click Open Anyway. The button stays for about an hour after you tried to open the app.
- 04Confirm with Open Anyway and your login password or Touch ID. Loopcut opens, and from then on it opens like any other app.
Right-click › Open no longer skips this check since macOS 15. On macOS 14 or earlier, Control-click Loopcut in Applications, choose Open, then Open again. If macOS says Loopcut “is damaged and can’t be opened”, that is the missing signature too: check the checksum below, then run xattr -dr com.apple.quarantine /Applications/Loopcut.app in Terminal and open it again.
Windows · 10 and 11
- 01If your browser says the file isn’t commonly downloaded, keep it. In Edge: the download’s ⋯ menu, Keep, then Show more › Keep anyway.
- 02Open the installer. If “Windows protected your PC” appears, click More info.
- 03Check the app is loopcut-v0.2.21-windows64.msi and the publisher reads Samuel Price, then click Run anyway.
- 04Click Yes when Windows asks to let it make changes. Loopcut installs, and from then on it opens like any other app.
The installer, the portable .zip and every program and library in them are signed by Samuel Price, which is what Smart App Control (Windows Security › App & browser control) looks for before it runs an app it doesn’t know yet.
Verify the download
Check the file is the one we published
GitHub records a SHA-256 checksum for every file attached to a release. This page reads it from GitHub together with the download link, so both always describe the same file. Run the command for your system on your copy; the result should match character for character.

After the download
Three steps to the first turn.
Loopcut is a full Blender build, so it lives next to your stock Blender and never touches its settings.
What the free account and paid plans include is on the pricing page. Only need cloud renders from a coding agent? You don’t need the app: render from Claude Code, Codex or Cursor.
- 01
Install and open
Loopcut is Blender with the agent built in. Import your existing Blender settings on first launch, or start fresh.
- 02
Connect
The setup asks you to create a free Loopcut account first: it holds your asset search and 100 free credits a month. Then click Sign in with ChatGPT so the agent runs on your Plus or Pro plan, or paste your own API key, or point it at a local model.
- 03
Ask for the boring part
Open a scene, press ⌘L (Ctrl+Alt+L on Windows), and describe the job. Read the code and approve it. Every turn that changes the scene is a checkpoint. Undo all restores the scene and the conversation to before it.
