This page describes how to install and uninstall JDK 8 for OS X computers.
This page has these topics:
Oculus SDK for OS X 0.5.0.1-beta Development Status. Our development for OS X and Linux has been paused in order to focus on delivering a high quality consumer-level VR experience at launch across hardware, software, and content on Windows. We want to get back to development for OS X and Linux but we don’t have a timeline. Currently, both Linux and Mac OS X running on Intel/AMD processors are supported. Although the SDK was initially bundled as part of the standard MESA distribution (from release 3708 onwards), it makes more sense to keep it separate. This page hosts all the necessary information and links to download, install and use the SDK. Fixed a regression on the 32-bit Windows OS where the emulator fails to boot Android 6.0 (API level 23) through Android 5.0 (API level 21) system images. (Issue 188326) General.
See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.

System Requirements
![For For](/uploads/1/1/3/6/113630565/619248506.jpg)
Observe the following requirements:
- Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.
- Administrator privileges.
This version includes the SDKs for iOS 14, iPadOS 14, macOS Catalina, tvOS 14, and watchOS 7. Download from the Mac App Store.
Note that installing the JDK 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.
Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.
JDK Installation Instructions
When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.
Depending on your processor, the downloaded file has one of the following names:
jdk-8u
version
-macosx-amd64.dmg
jdk-8u
version
-macosx-x64.dmg
Where
version
is 6 or later.- 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
.dmg
file to launch it.A Finder window appears containing an icon of an open box and the name of the.pkg
file. - Double click the package icon to launch the Install app.The Install app displays the Introduction window.Note:In some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the Continue button.
- Click Continue.The Installation Type window appears.
- Click Install.A window appears that says 'Installer is trying to install new software. Type your password to allow this.'
- Enter the Administrator login and password and click Install Software.The software is installed and a confirmation window appears.
- Refer to

for more information about the installation. - After the software is installed, delete the
.dmg
file if you want to save disk space.

Determining the Default Version of the JDK
Mac Os X Installer Download
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'.
There can be multiple JDKs installed on a system, as many as you wish.
When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.
You can determine which version of the JDK is the default by typing
java -version
in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:To run a different version of Java, either specify the full path, or use the
java_home
tool:![For For](/uploads/1/1/3/6/113630565/268787479.png)
For more information, see the java_home(1) man page.
Uninstalling the JDK
Download Apple Os For Windows
To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.
For example, to uninstall 8u6:
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.A software development kit (SDK) provides a set of files to build applications for a target platform, and defines the actual location of those files on the target platform or an intermediate platform that supports the target platform.
The Mac OS X platform provides SDKs for the following target platforms that RAD Studio supports:
- Mac OS X
- 64-bit iOS Device
- 32-bit iOS Device
- iOS Simulator
When you develop either Delphi or C++ applications for one or more of these target platforms, you must use the SDK Manager to add to RAD Studio an SDK for each target platform.
To add a new Mac OS X or iOS SDK to your development system from a Mac:
- Select Tools > Options > Environment Options > SDK Manager.
- Click the Add button.
- On the Add a New SDK dialog box, select a platform from the Select a platform drop-down list.
- The items in the Select a profile to connect drop-down list are filtered by the selected platform.
- Select a connection profile from the Select a profile to connect drop-down list, or select Add New to open the Create a Connection Profile wizard and create a new connection profile for the selected platform.
- The Select an SDK version drop-down list displays the SDK versions available on the target machine that is specified in the chosen connection profile.
- Select an SDK from the Select an SDK version drop-down list. For details and troubleshooting, see SDK Manager.
- Notes:
- RAD Studio does not support versions of the iOS SDK lower than 8.0.
- iOS applications built with a given SDK version may only run on that version or later versions of iOS. For example, an application built with version 9 of the iOS SDK might crash on a device running iOS 8.
- Notes:
- Check Mark the selected SDK active if you want the new SDK to be the default SDK for the target platform.
- Click OK to save the new SDK.

The files from the remote machine are pulled into the development system, so you can keep a local file cache of the selected SDK version. The local file cache can be used to build your applications for the SDK target platform.
After you create an SDK, you may change the local directory of your development system where RAD Studio stores its files.
If you do not create an SDK in advance, you can add one the first time you deploy an application to the remote machine. The Add a New SDK window appears where you can select an SDK version.
