Install and sign in

Download Zylcut for macOS, Windows or Linux from the download section.

Zylcut is not signed by Apple or Microsoft yet. The app is safe, but macOS and Windows warn about any app from a developer they have not verified, so the first launch needs a few extra clicks. After that, Zylcut opens normally. Linux needs no extra step.

macOS

Section titled “macOS”
  1. Open the downloaded Zylcut-…-arm64.dmg and drag Zylcut into Applications.
  2. Open Zylcut from Applications. macOS says it “could not verify Zylcut is free of malware”. Click Done. Do not move it to the Bin.
  3. Open System Settings (Apple menu > System Settings) and choose Privacy & Security in the sidebar.
  4. Scroll down to Security. Next to “Zylcut” was blocked to protect your Mac, click Open Anyway.
  5. Enter your Mac password (or use Touch ID) when asked.
  6. A last dialog appears. Click Open Anyway. Zylcut starts, and from now on it opens like any other app.

The Open Anyway button only appears for about an hour after step 2. If you do not see it, open Zylcut from Applications once more, click Done, and go back to Privacy & Security.

If you are comfortable with Terminal, this one command does the same as steps 2 to 6:

Terminal window
xattr -dr com.apple.quarantine /Applications/Zylcut.app

Windows

Section titled “Windows”
  1. Open the downloaded Zylcut-Setup-….exe. If your browser says the file is not commonly downloaded, choose Keep (in Edge: … > Keep > Show more > Keep anyway).
  2. Windows shows “Windows protected your PC” (Microsoft Defender SmartScreen). Click More info.
  3. Click Run anyway. The installer runs and opens Zylcut. From now on it starts normally from the Start menu.

Linux

Section titled “Linux”

Download the AppImage (make it executable with chmod +x Zylcut-*.AppImage, then run it) or the .deb (sudo apt install ./zylcut_*_amd64.deb). No extra step is needed.

Sign in

Section titled “Sign in”

Zylcut needs a free zylcut.com account. Choose Sign in with your browser, sign in there, and the app unlocks. Zylcut is free: there is no trial, card or time limit, and once signed in it keeps working offline. Your footage and projects never leave your computer.
