macOS may show a security warning because the app is not notarized with Apple. This is safe to bypass - follow these steps:
Open the DMG and drag to Applications
Double-click the downloaded .dmg file, then drag Langtrain Studio to the Applications folder
If you see "Cannot be opened" warning
Open Terminal (Cmd+Space, type "Terminal") and run:
xattr -cr /Applications/Langtrain\ Studio.app
Open the app
Launch Langtrain Studio from Applications - it should now open without warnings
💡 This is a one-time setup. The app is code-signed but not Apple-notarized, which is common for open-source software.
