Last month I wrote an article for MacStories on the extensibility and automation changes in OS X Yosemite. The second half was a basic overview of JavaScript for Automation (JXA) (the new addition to OS X scripting languages) joining AppleScript.
How do I install Java for my Mac?
This article applies to:- Platform(s): macOS
Mac System Requirements for Oracle Java 7 and later versions
- Intel-based Mac running versions 10.7.3 and above
- Administrator privileges
- A 64-bit browser (e.g., Safari)
- 32-bit browsers do not support Java 7 and later versions on the Mac platform
Note that Apple has removed NPAPI plugin support in its Safari browser version 12, and therefore Java Plugin cannot be enabled in Safari browser version 12 and above. More info
The screen shots and instructions below are for Java 8 Update 65 (8u65). If you are installing another version, make sure you change the version number appropriately.
Example: For Java 8 Update 65 (8u65) the file to download is jre-8u65-macosx-x64.pkg.
Notifications about disabled Java and restoring prompts
The installer notifies you if Java content is disabled in web browsers, and provides instructions for enabling it. If you previously chose to hide some of the security prompts for applets and Java Web Start applications, the installer provides an option for restoring the prompts. The installer may ask you to reboot your computer if you chose not to restart an internet browser when it prompted you to do so.
Test Installation To test that Java is installed and working properly on your computer, run this test applet.
