Java
The Java Control Panel is a macOS system preference pane that allows users to manage Java runtime settings, including which Java Development Kit (JDK) or Java Runtime Environment (JRE) is used by the system, configure Java security settings, manage certificates and exceptions, and adjust memory and plugin parameters. It is typically installed as part of the Java runtime distribution (Oracle JDK, Adoptium Temurin, Azul Zulu, or similar) and appears in macOS System Settings under Java preferences. The Control Panel is used primarily by developers and power users who need to switch between multiple Java versions or adjust system-level Java behaviour.

1 suggestionThe Java Control Panel is a preference pane component bundled with the Java runtime itself — it is not a standalone application, so there is nothing to update separately. Its presence and functionality depend entirely on which Java distribution (JDK or JRE) is installed on your Mac. If you are running an Intel-only Java distribution under Rosetta 2, that is what determines whether the Control Panel works natively. To ensure the Java Control Panel (and the underlying Java runtime) runs natively on Apple Silicon, you must install a native ARM64 build of Java from one of the actively maintained vendors: Oracle JDK (java.oracle.com, free for development use), Adoptium Eclipse Temurin (adoptium.net), Azul Zulu (azul.com), or BellSoft Liberica (bell-soft.com). All of these now ship native ARM64 builds for macOS. Homebrew can also install a native Java distribution by running brew install openjdk or brew install --cask temurin, and it will automatically detect your Mac's architecture and fetch the correct native build. Once you have a native Java distribution installed, the Java Control Panel will run natively as part of it. If you are still running an older Intel-only Java installation, you have until September 2028 (when Apple removes Rosetta 2 in macOS 28) to migrate to a native build — after that date, the Java Control Panel will not launch at all on your Mac.
