If you are still having issues, then you may try the followings:

Safe mode

Try updating your Mac in safe mode. Here is how:

• Startup your Mac in safe mode. To do that, turn off your Mac and then turn on your Mac and immediately press and hold the Shift key until you see the login screen. Then release the Shift key. And login.
• Now your computer is in safe mode. Try to update now.
• Then exit safe mode when you are done (in either case). To exit safe mode, restart your Mac normally, without pressing the Shift key.

Combo update

You can use a combo update to install Mac updates. Please note that before you continue, you may want to back up your Mac. You can back up with Time Machine or you can use iCloud.

Please note that combo updates let you update your Mac from a prior version of macOS within the same major release. A combo update is a combined update that means that it contains all of the changes since the original release of that major version. This further means that, using a combo update, you can update from macOS 10.15 directly to Mac OS X 10.15.2, skipping the 10.15.1. But you cannot go from, let’s say, 10.14.x to 10.15.x. For example, using a combo update, you cannot upgrade from macOS Mojave to macOS Catalina.

Please note that combo updates are huge. Here is how you can use them:

• Visit Apple’s combo updates site: https://support.apple.com/downloads/macos
• Find the right combo update. And download it. As stated above, they can be huge. The combo will download as a .dmg file.
• Now quit all apps on your Mac.
• Double-click the downloaded file, if it does not start automatically.
• Follow the onscreen instructions.

Using macOS Recovery to update your Mac

If you still could not update, you may try this. To do this, you need to restart your Mac from macOS Recovery. Using the method below, you will be able to upgrade to the latest macOS that is compatible with your Mac. Here is how:

• Turn off your Mac.
• Turn on your Mac and immediately press and hold the Option-⌘-R keys together until you see the Apple logo or the spinning globe icon.
• Login.
• Click Reinstall macOS and follow the onscreen instructions.

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.

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

1. 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.

2. 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.
3. Double-click the JDK 13.pkg icon to start the installation application.
   The installation application displays the Introduction window.
4. Click Continue.
5. Click Install.
   A window appears that displays the message: Installer is trying to install new software. Enter your password to allow this.
6. Enter the Administrator user name and password and click Install Software.
   The software is installed and a confirmation window is displayed.

Uninstalling the JDK on macOS

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.

1. Go to /Library/Java/JavaVirtualMachines.
2. 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

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:

Download Java 8 For Mac

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

Java 6 Se Download Mac
