In this article, I will demonstrate how to install Java OpenJDK 15 on macOS Catalina in 2020.
Download and Install OpenJDK 15
MacOS Catalina, the latest version of the world’s most advanced desktop operating system, is now available as a free software update. With macOS Catalina, users are able to enjoy Apple Arcade, a groundbreaking new game subscription service featuring new, exclusive games from some of the world’s most creative developers. If you like Mac OS X interface, and you want to make your Linux looks like a Mac OS X, then you came to the right place. We are going to list some great Mac OS X themes for Linux. There are many new and updated GTK3 themes that will make your Linux looks like Mac OS X. As you might know, the new Mac OS X Catalina is about to release. Download Java for OS X directly from Oracle. Get the latest version If an app or webpage you want to use asks you to install Java software, you can download the current version of Java for OS X directly from Oracle's website. Java 6 cannot currently be installed on macOS 10.15 Catalina because there is a newer version of Java installed on the system. Attempts to reinstall legacy Java libraries upon upgrade of the OS may result in errors restricting installation.

Before You Begin
- Mac OS X 10.8 or higher
- Ensure that you have Administrator privileges on the system.
- Ensure that you have 350 MB free on your computer's hard drive.
- If you are logged into SAPgui, log off and 'Quit' the SAPgui application.
- If you have an SAP folder on your hard drive within the Applications folder, make a note of the name of the folder. You will be able to revert to the prior version if necessary.
Pre-Installation Instructions
A. SAPgui and Kerberos Tickets
Acquire Kerberos tickets. Tickets are required to connect to SAP systems
- SAPgui may bring up the Ticket Viewer to prompt you to obtain Kerberos tickets. If not:
- You may see an error mentioning 'GSS-API'
- SAPgui may stall at 'Connecting...'
- Your SAPgui session may freeze.
All of these behaviors mean that either you do not have Kerberos tickets, or your Kerberos tickets have expired. To resolve that issue, use the instruction below to get tickets manually.
- How to get Kerberos tickets manually
- Launch Kerberos Ticket Viewer (/Applications/Utilities/Ticket Viewer). On Mac OS Catalina it is located in (/System/Library/CoreServices/Applications)
- Enter your Kerberos username (the first part of your @mit.edu email address), and your Kerberos password (the password used to check your @mit.edu email).
- If You cannot find the Ticket Viewer app (Catalina OS) then (re)install the Java JDK, reboot and it should show up.
NOTE: Your Kerberos tickets will last for 10 hours only, and have to be manually renewed if you wish to remain in SAP longer. If you do wish to remain in SAP longer than 10 hours, it's a good idea to renew them at least 20 minutes or so before they expire.
