Before you install

Release builds aren't code-signed yet. On macOS, Gatekeeper blocks the first launch: right-click Shellium and choose Open, or run xattr -dr com.apple.quarantine /Applications/Shellium.app. On Windows, SmartScreen may ask you to confirm. Each release ships a SHA256SUMS.txt you can check your download against.
