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. Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. It is now an optional install that you must select. Notice that the Java.runtime/ directory honors the standard bundle format. This is important if you plan to code-sign your application, in that codesign simply won’t work if the bundle isn’t a macOS bundle. When we built the JRE with jlink, the example should have produced a directory named “Home”; the Home directory above should be this entire directory.

A: If you have not yet installed Apple's Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in.

- Watch the companion video: How to use Java in the new Microsoft Edge
Some users may need internet artifacts like the Java browser plugin to run legacy apps that require it. The options to run Java apps are few and far between these days. Yet it is possible to use Microsoft’s new Edge web browser — the Chromium-based version of Edge — to run Java apps. Assuming you have Java installed on your computer, the only requirement is an intermediary in the form of an extension.
What makes Java support possible in the new Chromium-based Microsoft Edge is Edge’s support of Chrome extensions. If you are still running the old version of Edge, it handles the need for running Java apps in a completely different way. Although Microsoft has its own extensions library, you won’t find what you are looking for there. Edge users with Java needs must visit the Chrome Web Store instead to install the one discussed here.
Java in the new Microsoft Edge using IE Tab
One method to use Java in the new Microsoft Edge is to install the IE Tab extension. The “IE” in IE Tab is an abbreviation for Internet Explorer. Available for Edge from the Chrome Web Store, IE Tab emulates Internet Explorer within an Edge browser window. The extension uses the Internet Explorer rendering engine to display Java content (as well as ActiveX and Silverlight content). It is easy to install, and even easier to use. It is important to note that IE Tab works on Windows machines only.
Visit the IE Tab page in the Chrome Web Store. Click the blue Add To Chrome button. A dialog will display asking you if you want to Add IE Tab, accompanied by a list of functions it can perform. Click the Add extension button.
Once installed, the IE Tab icon in Microsoft Edge displays next to Edge’s address bar. Click the icon to open an IE Tab. In the IE Tab, input the web address of a page that contains Java content. In the example below, our Java version verification was successful. The page uses a Java detection applet, with the latest version of Microsoft Edge using an IE Tab.
Try that same verification process in a regular Edge tab, and a notification that, “We are unable to verify if Java is currently installed and enabled in your browser,” displays instead.
Java Web Start, No Browser Required
If you have the Java plugin on your Windows machine, then you have Java Web Start (JWS). The question is does the Java application you want to run use JWS technology? JWS launches automatically if you download a Java app that uses it (usually in the form of a .jnlp file). Check the Java app developer’s website to see if they have a JWS download link for their app. If they do, download it and save a shortcut on your desktop when prompted by JWS. Double-click the shortcut to run the app.

Also included with JWS is a Java Cache Viewer. Use Cache Viewer to launch applications you have already downloaded. Here’s how:
1. Launch the Java Control Panel (Control Panel > Programs > Java icon). Double-click the Java icon.
Mac Os Java Runtime
2. Under the General tab, click the View button in the Temporary Internet Files section to launch the Java Cache Viewer in a separate window.
3. Double-click an application listed in the Java Cache Viewer to launch it without needing a web browser.
If the Java app you want to use is not listed or does not launch when double-clicked, contact the app’s developer.

An error “you need to install the legacy Java SE 6 runtime”, is encountered when you open any Adobe application.
With Mac OS 10.7 (Lion) and later, the Java runtime is no longer installed automatically as part of the OS installation. Follow any of the methods below to install Java runtime.
You can download and install the latest Java runtime from the Java website - Download Free Java Software.
Note:
On Mac OS 10.10 (Yosemite), when you launch any Adobe product, you might receive a warning 'The Application has been moved and its path has been changed...'.
Click Repair Now or Update button to update the location and resolve the issue. When prompted for password, enter your system password to complete.
If Java runtime is not installed, you are prompted to install when you first launch any Adobe product. Follow the onscreen instructions in the Java required notification dialog box to install.
Use the following method to initiate the Java runtime installation or confirm if it is installed.
- Go to Applications > Utilities > Java Preferences.
- If Java is not installed, you receive the following message: “To open “Java Preferences,' you need a Java runtime. Would you like to install one now?”
- Click Install and accept the license agreement. The Java runtime is downloaded and installed.

Java Jre For Mac Os 10.12
Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.
Java Jre For Macos 64-bit
If the Java runtime is not installed, some issues that are known to occur include -
Java Jre Macos Catalina
- Failure to launch.
- Install Java runtime prompts when you attempt to use the applications.
- Applications hang or quit.
