If you want to develop applications for Java, download the Java Development Kit, or JDK™. The JDK includes the JRE, so you do not have to download both separately. JRE 8u261 Checksum. Java SE Runtime Environment 8u261. This software is licensed under the Oracle Technology Network License Agreement for Oracle Java SE. Java is a runtime environment maintained by Oracle that you must install on your Mac to be able to run applications written using the Java programming language. Moreover, Java allows developers to make apps available on multiple operating systems at the same time because Java-based utilities.

Since downloading and installing OS X Yosemite, I was required to search Oracle.com to download the newer version of Java 8.20+ in order to continue using Java on the new OS. I followed the Pop Up Box linking to the Oracle.com page. I followed the instructions and seemed out 'JRE DOWNLOAD' for Java SE Runtime Environment 8. I downloaded and installed the proper version for my MAC OS. The software version was Java v8.25.

Since that time, I keep running into the same minor problem after I boot up my 17' Macbook Pro Retina. It continually gives me this Pop Up Box:

'You are running Mac OS X 10.10, which is currently an unsupported platform for Java 7. Starting with Java 8 Update 20 (8u20), download and install Java 8 from oracle.com.'

I don't see anything improper workings and I just want to remove this unwanted warning with a correct fix. Please give your input. Thank you in advance.

System Requirements for Installing the JDK on macOS

The following are the system requirements for installing the JDK on macOS:

Any Intel-based computer running macOS.
Administrator privileges.
You cannot install Java for a single user. Installing the JDK on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK on macOS.

Determining the Default JDK Version on macOS

When starting a Java application through the command line, the system uses the default JDK.

There can be multiple JDKs installed on the macOS system.

You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 13 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 13. For example:

To run a different version of Java, either specify the full path, or use the java_home tool. For example:

$ /usr/libexec/java_home -v 13 --exec javac -version

Installing the JDK on macOS

Download the JDK .dmg file, jdk-13.interim.update.patch_osx-x64_bin.dmg.
Before the file can be downloaded, you must accept the license agreement.
From either the browser Downloads window or from the file browser, double-click the .dmg file to start it.
A Finder window appears that contains an icon of an open box and the name of the .pkg file.
Double-click the JDK 13.pkg icon to start the installation application.
The installation application displays the Introduction window.
Click Continue.
Click Install.
A window appears that displays the message: Installer is trying to install new software. Enter your password to allow this.
Enter the Administrator user name and password and click Install Software.
The software is installed and a confirmation window is displayed.

After the software is installed, you can delete the .dmg file if you want to save disk space.

Uninstalling the JDK on macOS

You must have Administrator privileges.

Note:

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time that you perform an update of the OS.

Go to /Library/Java/JavaVirtualMachines.
Remove the directory whose name matches the following format by executing the rm command as a root user or by using the sudo tool:
/Library/Java/JavaVirtualMachines/jdk-13.interim.update.patch.jdk
For example, to uninstall 13 Interim 0 Update 0 Patch 0:
$ rm -rf jdk-13.jdk

Installation FAQ on macOS Platform

This topic provides answers for the following frequently asked questions about installing JDK on macOS computers.

1. How do I find out which version of Java is the system default?

When you run a Java application from the command line, it uses the default JDK. If you do not develop Java applications, then you do not need to worry about this. See Determining the Default JDK Version on macOS.

2. How do I uninstall Java?

See Uninstalling the JDK on macOS.

3. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 13?

If you want to continue to develop with Java 6 using command-line, then you can modify the startup script for your favorite command environment. For bash, use this:

$ export JAVA_HOME=`/usr/libexec/java_home -v 13`

Some applications use /usr/bin/java to call Java. After installing Java for macOS 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java-related command-line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.

4. What happened to the Java Preferences app in Application Utilities?

Download Java 8u20 For Macbook Pro

The Java Preferences app was part of the Apple Java installation and is not used by Oracle Java. Therefore, macOS releases from Apple that do not include Apple Java will not include Java Preferences.
