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.
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.
If the Java runtime is not installed, some issues that are known to occur include -
- Failure to launch.
- Install Java runtime prompts when you attempt to use the applications.
- Applications hang or quit.
This page describes how to install and uninstall JRE 8 on OS X computers.
Note:The JRE installation includes the JavaFX Runtime which is incorporated into the same directory structure.
This page has these topics:
See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.
See 'OS X Platform Install FAQ' for general information about installing JRE 8 on OS X.
Observe these requirements:
Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.
Note that installing the JRE on OS X is performed on a system-wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
Only one JRE can be installed at a time. The system will not install a JRE that has a lower version than the current version. If you wish to install a lower version of the JRE, uninstall the current version as described in 'Uninstalling the JRE'.
Installing a JRE from Oracle will not update
java -version symlinks or add
java to your path. To be able to do this, you need to install the JDK.
JRE Downloaded File
Depending on your processor, the downloaded file has one of the following names, where
version is the update number:
Installing JRE 8u40
If you are installing JRE 8u40, then follow these steps:
Download the file.
Before the file can be downloaded, you must accept the license agreement.
From either the Downloads window of the browser, or from the file browser, double click the file
.dmgto launch it.
A Finder window appears containing an icon of an open box and the name of the
Double click the package icon to launch the Install app.
A window appears that says, 'Java 8 Update 40 is trying to install a new helper tool. Type your password to allow this.'
Enter the Administrator login name and password and then click Install Helper.
The Install app then displays the Introduction window.
Oracle has partnered with companies that offer various products. The installer may present you with the option to install these programs when you install Java. Specify if you want these programs installed and then click Next.
Note:You can disable the presentation of offers during installation by specifying the
--args SPONSORS=0option in the terminal command line. For example:
open /Volumes/Java 8 Update 40/Java 8 Update 40.app --args SPONSORS=0
An Installation Progress window is displayed. Once the software is installed, a confirmation window appears and then an applet is launched to verify the version of Java installed.

Determining the Installed Version of the JRE
If you have not yet installed Apple's Java 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 OS X that Include Apple Java 6 Plug-in'.
Only one JRE can be installed. Installing a JRE removes the previously installed JRE. The JRE version used by the system can be determined in one of two ways:
From System Preferences click the Java icon from the Other category. This launches the Java Control Panel. Click About.
Type the following in a Terminal window (note escaped space character, ignore line break):
The system will not install a JRE that has a lower version than the current version. If you want to install a lower version, first uninstall the existing version.
Uninstalling the JRE
To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.
Remove one directory and one file (a symlink), as follows:
Java Jdk For Mac
/Library/Internet Plug-Insand remove the
Navigate to /
Jre 8 Mac
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 you perform an update of the OS.
