GeoMapApp©Steps to Upgrade to Java 7 or Higher for Mac Users

GeoMapApp version 3.5.0 and above require that you are running Java 7 or higher on your Mac. If you already have Java 7 or higher installed, you should be able to run GeoMapApp. If, though, you are running Mac OS X versions 10.7 or above but have an older version of Java, you will need to install a newer version of Java to run GeoMapApp. The steps below explain how to upgrade your Java, for which you will need administrator privileges.

If, after following the steps below, you are still experiencing problems running GeoMapApp, please contact us at with a detailed explanation of the issue and any screen shots that might be helpful.

How to upgrade to Java 7 or higher on Mac OS X 10.7.3?

Step 1:
Go to  Menu on the top left corner of your screen, then to About This Mac and check which OS X you are running on. If it is 10.7.3 or higher then proceed to step 2. Users of Lion Mac OS X 10.7.1 and 10.7.2 should upgrade to 10.7.3 or later versions, so you can get the latest Java version from Oracle. If your OS X is less than version 10.7.0 you will need to upgrade your OS X platform to a higher version. It is at your discretion to proceed and back up any data you have before you proceed with the major OS X upgrade.

Step 2a:
Once you have determined you have the correct OS X version as a requirement to run Java 7 you may proceed. Go to your Systems Preferences window. If you have Java 7 or later versions, you will see a Java icon under System Preferences on the bottom row. If this icon is present go to step 3. If you do not see this icon continue on with step 2b - 2d to get the latest Java version from Oracle.

Step 2b:
Java is not pre-installed with Mac OS X versions 10.7.3 and above. To get the latest Java from Oracle, you will need an Intel-based Mac running Mac OS X version 10.7.3 (Lion) and above. To confirm that you have the latest version of Java from Oracle please visit their verification page.

Step 2c:
Depending on which browser you have you may be prompted that you need to enable your Java plugin for your web browser. This is different than the Java Control Panel for Desktop applications. In this example we are using a Safari web browser. You will see a prompt to allow the Java plug-in. Click Download Java Now and proceed to click Agree And Start Free Download. If you do not see the button to do this try the verification page with a different browser (Firefox).

Step 2d:
A .dmg file should be available in your downloads folder. For this example it is named jre-8u45-macosx-x64.dmg.

Step 2e:
Double click it to begin the installer and follow the steps.

Step 2f:
Try the verification page again. Clicking should confirm a successful message.

Step 3:
Click on the Java Icon in your Systems Preference window. This should launch a separate Java Control Panel. Navigate to the Update Tab located near the top of the Java Control Panel.

Step 4:
Check you Java version here. If you already have Java 7 installed, that is suitable to run GeoMapApp. It is recommended, though, that you update to the latest version - currently Java 8. Clicking the Update Now button will bring up a Installer window.

Step 5:
GeoMapApp version 3.5.0 and above should be now running on your Mac OS X machine with Java 7 and above.
