Java version '1.8.0161' Java(TM) SE Runtime Environment (build 1.8.0161-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode) Conclusion Again, it seems pretty straight forward and it is but before some research it was still a little unclear. If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.
After upgrading to a newer version of Mac OS X (Yosemite 10.10 and El Capitan 10.11) or macOS (Sierra 10.12 and High Sierra 10.13), you may end up getting an annoying new pop-up message whenever you start your computer. It says, “To use the java command-line tool, you need to install a JDK.” It asks you to click “More Info” and visit the JDK (Java Developer Kit) download website.
The reason you’re receiving this message is due to the removal of Java support in newer versions of OS X for security reasons. Older software such as Adobe Photoshop and Illustrator requires legacy Java support. Without a compatible Java command-line tool for these software, you’ll get this pop-up every time you turn on your Mac computer.
When you visit the download website to update Java, you find that the issue isn’t resolved! You’re still getting the same pop-up. This isn’t a complicated issue to fix, but it is an indirect one. The problem is that you’re not being routed to the correct download website when you click “More Info.”
