  Notes: macOS will deny running jLog because it is not signed and therefore considered being from an unidentified developer. Open System Preferences and go to Security & Privacy, and make sure the General tab is selected. If you've been blocked from opening an app within the past hour, this page will give you the option to override this by clicking the temporary button 'Open Anyway'. You'll be asked one more time if you're sure, but clicking Open will run the app. Se pictures below.


  1. Double-click jLog.dmg and drag the jLog app to the Applications folder (or another folder of your choice). The application is read-only and can run from any folder (including directly from the installer, e.g. to try a new version before installing it into Applications).
