Installation Instructions


Mac OS Compatibility

My apps work with Mac OS 10.9 Mavericks * (and earlier versions back to 10.6 Snow Leopard).

* For 10.7 and later you may need to change your Security settings and install Java. (Scroll down.)

I don’t have the resources to promptly test my apps with each new version of the Mac OS. If you have a problem that seems OS related please tell me and I’ll try to fix it.

How To Install My Applications

  1. Click on the download link for the app you want to install. It will start downloading.
    Click Download Link
  2. Double-click the .DMG file to mount the disk image on your Desktop like a drive. Open it.
    Open the Disk Image
  3. Drag the contents of the disk image into your Applications folder and open it from there.
    Drag to your Applications Folder
    (You can drag the disk image to the trash and delete the .DMG file now too.)

The Application Can’t Be Opened

You might get this message when you launch my apps if you’re using Mac OS 10.7 or later:

Gatekeeper warning

If so, you’ll need to disable GateKeeper (a security feature that blocks all programs unless they are approved by Apple.)

  • Go to System Preferences / Security & Privacy / General tab and change the settings so they look like this:
    GateKeeper - Allow All

You Need Java Runtime

You might get this Java message when you launch some of my apps:

Install Java

  • Just click “Install” and everything will be fine. (I make my apps with the MAX visual programming system. Some MAX functions require Java but newer versions of the Mac OS don’t come with Java pre-installed.)
