After updating to Mac OS X 10.3.9, some systems may have issues with Java. When you install the JRE, you can install only one JRE on your system at a time. This update will correct issues affecting some Java users following the installation of Mac OS X v10.3.9 Software Update. To install an earlier version of the JRE, you must first uninstall the current version. Single User Mac OS X 10.5 or Newer From OS X 10.5, Apple introduced a command line tool ( /usr/libexec/javahome ) which dynamically finds the top Java version specified in Java Preferences for the current user. To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. However, the system will not replace the current JRE with a lower version. When you install the JDK, it also installs the JRE. Administrator privileges are required to install the JDK and JRE on macOS. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. You cannot install Java for a single user. Download the mentioned version of Java for OS X 10.9 OR above. However, as of now, you can install and run non-notarized software on macOS 10.15 systems by modifying your security preferences.
Therefore, we cannot certify any JDK version on macOS 10.15 yet. Open ‘system preferences’ > ‘user & groups’ > create ‘new account’. Platform(s): Mac OS X Changes introduced with macOS 10.15 (Catalina) cause certain Java applications to behave incorrectly. Restart mac and follow given instructions. For this reason, it is strongly recommended that Developer Previews of Java on Mac OS X be installed on non-critical systems.The following are the system requirements for installing the JDK and the JRE on macOS: Steps: Uninstall the currently installed Java version from mac OS X Mavericks. The same applies for any other Java-related Software Updates or Developer Previews. Therefore, the only way to revert to an earlier Java installation is to reinstall the operating system. Q: Can I remove a Java update after I've installed it?Ī: Java on Mac OS X is updated incrementally through numerous releases. A bug was fixed in 8u20 which had prevented the installation of prior releases of Java on Mac OS X 10.10. HOWEVER - doing a "repair" type install on the OS did work. I am hoping they can patch it, because I don't want to reinstall the apps I had to reinstall after the OS reinstall.
The system now will not start up normally (I have to hold the power button down, wait for the long beep tone, etc.) If you have problems with Java 6, contact Apple Technical Support. Java 7 and later versions are not supported by these older versions of Mac OS X.
At that time I did not know the JAVA update was the culprit - but when I just updated it again the problem re-occurred. Use Software Update available on the Apple menu to check that you have the most up-to-date version of Java 6 for your Mac. Alternately, Mac users can fire up the Software Update. Tiger and Leopard users alike may download the new software using the link below.

When I reinstalled the OS it worked normally. The same goes for Java for Mac OS X 10.5 Update 3.
