Ever since Lion (OS X 10.7), Apple has hidden your personal Library folder (/Library) by default. In Lion and Mountain Lion (OS X 10.8), you could make the folder visible, but it required some work. Jul 22, 2011  All you need to do is hit Command+Shift+G from the Mac desktop (or Finder Go Go to Folder) and type in /Library to temporarily access the Library directory in the Finder. When you are done, close this window and it will no longer be visible.

This page describes how to install and uninstall JDK 8 for OS X computers.

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 JDK 8 on OS X.

System Requirements

Observe the following requirements:

• Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

• Administrator privileges.

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-8uversion-macosx-amd64.dmg

• jdk-8uversion-macosx-x64.dmg

Where version is 6 or later.

1. Download the file.

   Before the file can be downloaded, you must accept the license agreement.

2. 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.

3. 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.

   
   

4. Click Continue.

   The Installation Type window appears.

5. Click Install.

   A window appears that says 'Installer is trying to install new software. Type your password to allow this.'

6. Enter the Administrator login and password and click Install Software.

   The software is installed and a confirmation window appears.

7. Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.

8. After the software is installed, delete the .dmg file if you want to save disk space.

Determining the Default Version of the JDK

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 more information, see the java_home(1) man page.

Uninstalling the JDK

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:

Mac Install Java

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.

Learn how to access the hidden Library folder in your Home folder on your Mac so you can tweak app settings and access app files.

Inside the home folder on your Mac is a Library folder that stores app-specific files and settings, personal settings, and some data. The files and settings in the Library folder should be left alone for the most part. But, you may want to tweak the settings for an app, which may require accessing the Library folder. Or, maybe an app backs up data to the Library folder and you want to copy that to an external drive.

As of Mac OS X Lion (10.7), the Library folder in your home folder is hidden by default. That doesn’t mean you can’t get to it. It’s hidden so you don’t accidentally delete settings and data, damaging apps in the process. So, if you decide you want to access the Library folder, be very careful.

Today we’re going to cover different ways of accessing the hidden Library folder in your home folder and how to make it permanently available in Finder.

What is the Path to the Library Folder?

Java Library Location On Mac Computer

The Library in your home folder is written as ~/Library. The tilde (~) character is a shortcut for your home directory. For example, on my Mac, that would expand to /Users/lorikaufman/Library.

Access the Library Folder Using the Go to Folder Option

If you want to access the Library folder only occasionally, you can use the Go to Folder option in Finder.

Open Finder or just click on the desktop. Head to Go > Go to Folder, or hit Cmd + Shift + G.

Type:~/Library in the Go to the folder box on the dialog box and click Go or press Enter.

If you have one or more Finder windows open, the Library folder opens in the currently active window. If no Finder windows are open, a new one opens to the Library folder.

Access the Library Folder Using the Terminal

If you prefer using the command line, you can access the Library folder using the Terminal.

Go to Utilities > Terminal in the Applications folder. To access the Library folder directly in the Terminal, type:cd ~/Library at the prompt to switch to the Library folder.

You can type:ls at the prompt to get a detailed folder listing. You can work with the files in the Library folder directly on the command line. Just be careful.

You can also use the Terminal to open the Library folder in a Finder window. Type:open ~/Library at the prompt and hit Enter.

Access the Hidden Library Menu Option in Finder

The Library folder is available on the Go menu in Finder, but it doesn’t show on the menu by default.

To temporarily show the Library option on the Go menu, open the menu and press the Option key. The Library folder shows up between Home and Computer on the Go menu. Keep the Option key pressed while you move your mouse down the menu and select Library.

If you’re using a Windows keyboard with your Mac, press the Alt key.

Show the Library Folder Permanently in Finder

If you access the Library folder often, you can permanently show the Library option on the Go menu and the Library folder in your Home folder.

Open Finder and head to your Home folder using the left pane or by pressing Cmd + Shift + H. Then, go to View > Show View Options, or hit Cmd + J.

A dialog box displays with options you can set for your Home folder. Check the Show Library Folder box at the bottom of the dialog box. The Library folder now shows up in your Home folder in Finder windows and the Library option becomes permanently available on the Go menu.

When you permanently show the Library folder in Finder, you can hit Cmd + Shift + L to open it in a Finder window, in addition to selecting the Library option on the Go menu.

Happy Tweaking, But Be Careful

How To Update Java On Mac

The Library folder is hidden by default for a good reason. So, before tweaking settings and changing files in the Library folder, make sure you know what you’re doing.
