OpenScreen is available as a native desktop application for macOS, Windows, and Linux. Follow the installation instructions for your operating system below.

​
Download OpenScreen

Download the latest installer for your platform from the GitHub Releases page. Look for the appropriate file:
  • macOS: .dmg file
  • Windows: .exe installer
  • Linux: .AppImage file

​
macOS Installation

1

Download the installer

Download the .dmg file from the releases page and open it.
2

Install the application

Drag the OpenScreen app to your Applications folder.
3

Bypass Gatekeeper (if needed)

Since OpenScreen doesn’t have a developer certificate, macOS Gatekeeper may block the app from opening. To bypass this restriction, run the following command in Terminal:
xattr -rd com.apple.quarantine /Applications/Openscreen.app
You need to grant your Terminal app Full Disk Access in System Settings > Privacy & Security before running this command.
4

Grant permissions

After running the command, navigate to System Preferences > Security & Privacy and grant OpenScreen the necessary permissions:
  • Screen Recording - Required to capture your screen
  • Accessibility - Required for keyboard shortcuts and app detection
5

Launch OpenScreen

Open OpenScreen from your Applications folder. You’re ready to start recording!

​
Troubleshooting macOS Issues

Make sure you’ve run the xattr command to remove the quarantine flag and granted Full Disk Access to your Terminal app.
Go to System Preferences > Security & Privacy > Privacy > Screen Recording and ensure OpenScreen is checked. You may need to restart the app after granting permissions.

​
Windows Installation

1

Download the installer

Download the .exe installer from the releases page.
2

Run the installer

Double-click the installer file and follow the on-screen instructions.
3

Complete installation

The installer will install OpenScreen and create a desktop shortcut.
4

Launch OpenScreen

Windows Defender or your antivirus software may show a warning since the app is not signed. You can safely proceed with the installation.

​
Linux Installation

1

Download the AppImage

Download the .AppImage file from the releases page.
2

Make it executable

Open a terminal in the directory where you downloaded the file and run:
chmod +x Openscreen-Linux-*.AppImage
3

Run OpenScreen

Execute the AppImage:
./Openscreen-Linux-*.AppImage
4

Grant permissions (if needed)

Depending on your desktop environment, you may need to grant screen recording permissions. The specific steps vary by distribution:
  • GNOME: Settings > Privacy > Screen Sharing
  • KDE Plasma: System Settings > Workspace Behavior > Screen Locking
  • Other: Consult your desktop environment’s documentation

​
Linux Troubleshooting

If you encounter a sandbox error, run OpenScreen with the --no-sandbox flag:
./Openscreen-Linux-*.AppImage --no-sandbox
Running with --no-sandbox reduces security isolation. Only use this flag if the app won’t launch normally.
Some older Linux distributions may be missing required libraries. Install these packages:Debian/Ubuntu:
sudo apt install libgtk-3-0 libnotify4 libnss3 libxss1 libxtst6 xdg-utils libatspi2.0-0 libuuid1
Fedora/RHEL:
sudo dnf install gtk3 libnotify nss libXScrnSaver libXtst xdg-utils at-spi2-core libuuid

​
System Requirements

To run OpenScreen smoothly, your system should meet these minimum requirements:

​
Minimum Requirements

  • CPU: Dual-core processor (2 GHz or faster)
  • RAM: 4 GB
  • Storage: 200 MB free space
  • Graphics: Hardware acceleration support

​
Recommended for 4K Recording

  • CPU: Quad-core processor (3 GHz or faster)
  • RAM: 8 GB or more
  • Graphics: Dedicated GPU with hardware encoding support
  • Storage: SSD with 1 GB+ free space for recordings
OpenScreen automatically adjusts recording quality based on your hardware capabilities. If your system can’t maintain 4K@60fps, it will fall back to lower resolutions while keeping quality as high as possible.

​
Verifying Installation

After installation, verify that OpenScreen is working correctly:
  1. Launch the application
  2. Check that the source selector window appears
  3. Select a screen or window to record
  4. Click the record button to start a test recording
  5. Stop the recording and verify the video editor opens
If everything works, you’re ready to move on to the Quick Start guide!

OpenScreen doesn’t have automatic updates yet. To update:
  1. Check the releases page for new versions
  2. Download the latest installer for your platform
  3. Install the new version (it will replace the old one)
Your project files and custom settings are preserved during updates.
