How To Change Java Security Settings On Mac
Starting with Java eight Update xx (Java 8u20) and later versions the option to lower the security setting in the Coffee Panel Panel to Medium has been removed. Prior, changing the setting to Medium would quickly resolve bug where sure unsigned Java applets would non run. At present, with Java 8u20 and later, only Loftier and Very High levels are available. These security levels are described on the coffee.com website as stated below.
Very Loftier
This is the about restrictive security level setting. All the applications that are signed with a valid document and include the Permissions attribute in the manifest for the master JAR file are immune to run with security prompts. All other applications are blocked.
High
This is the minimum recommended (and default) security level setting. Applications that are signed with a valid or expired certificate and include the Permissions attribute in the manifest for the main JAR file are allowed to run with security prompts. Applications are as well allowed to run with security prompts when the revocation status of the certificate cannot be checked. All other applications are blocked.
Medium (removed from Java 8 Update 20 and later versions)
Only unsigned applications that request all permissions are blocked. All other applications are allowed to run with security prompts. Selecting the Medium security level is not recommended and will make your computer more vulnerable should you run a malicious application.
This new default, although enabled for security reasons, presents challenges for those simply wanting to run unsigned applets they trust locally on their PC or those developing applets or simply learning how to code who desire to run applets for quick testing. Below, I demonstrate how to resolve this on Mac Bone X Yosemite (10.10.1) past updating the security settings. Note, new Java security defaults were implemented for additional security precautions, so you may desire to apply the below method only when needed and and then revert dorsum one time complete.
- Click on the Apple icon on the top left of the screen, and select System Preferences.
- Click on the Java icon.
- Click on the Security tab.
- Click the Edit Site Listing… button; so click the Add button; adjacent, type file:/ and hit enter. Finally, click Ok.
You should now see the beneath.

Y'all can now just double click an html file with Java applet code and have it run as expected. For demonstration purposes, I created a simple Java Applet with the beneath code.
HumairApplet - Example Java Applet Code
Next, I compile the Java code into bytecode with the javac HumairApplet.java command at the cli. I then, add this form to my HTML lawmaking as shown below. Note, for this case, my applet grade and HTML file are in the same folder.
