Download the jLog application for Mac OS X

The installer and optional files are available under these License conditions:

  jLog V 5.4.5
jLog V 6.1jLog V 6.4
jLog installer program Java 6: jLog.dmg Java 6: jLog6-1.dmg

Java 8
: jLog.dmg

Java 9+: jLog.dmg *)


  Notes: macOS will deny running jLog because it is 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. Log in as the preferred user (need Administrator privileges) and download the installer program that corresponds to the selected version of jLog, e.g. to the Desktop (folder).
  2. jLog V5.x: 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).


*) Should run with Java 9, Java 10 and Java 11 (and even the Java 12-ea prerelease)

How to open jLog after download
