Before you install
Toploader OS is a free download for Windows and macOS. Get the latest version, install it in minutes, and start building your inventory or collection right away.
Choose your platform and build
On Windows, pick the installer (no admin rights needed, Start Menu shortcut, clean uninstall) or a portable zip. On macOS, download the Apple Silicon or Intel DMG.
Get past the unsigned-build warning
Toploader OS isn’t signed with a paid code-signing certificate, so Windows SmartScreen or macOS Gatekeeper may warn about an unidentified developer the first time you open it — this is expected. On Windows, choose More info → Run anyway; on macOS, right-click the app and choose Open.
