How to enable the Java Console on Mac
You may need to diagnose Java implementation issues on your Mac computer. If so, it may be helpful to gather Java-related messages from your computer’s Java Console. A support team may request this information, which is also know as “output”. Below are the steps to enable the Java Console on Mac when there is a request for Java Console output, or you need to reference it:
1. Click the Apple menu, and select System Preferences from the drop-down menu.
2. System Preferences will launch in a new window. Double-click the Java icon.
3. The Java Control Panel will launch in a new window. Click the Advanced tab. Under the Java Console section, click the Show console radio button.
When you select Show console, click the Apply button, then click the OK button. The Java Control Panel will close.
You may select Hide console to enable the Java Console only without launching it automatically when you encounter Java content in your web browser. The Java Console will only display when you select to launch it.
To disable the Java Console so it does not start when you encounter Java content in your web browser, select the Do not start console radio button. This is the option you would select when you no longer need to display the Java Console. Should an occasion arise when you need to reference the Java Console again, simply select Show console again.
4. When you select Show console, your Java Console will launch in a new window when you encounter Java content in your web browser.
To provide the Java Console output to a requesting support team, highlight all of the text within the Java Console window, then click the Copy button at the base of the Java Console window to add the highlighted text to your computer’s clipboard. From the clipboard, you may paste the Java Console output you copied into an email or document of your choice.
