See JDK 7 and JRE 7 Installation Guide for general information about installing JDK 7 and JRE 7.
With Mac OS X 10.6 ('Snow Leopard') you're limited to the Java 6 version provided by Apple. If your hardware won't support Lion you will probably have to use Arduino 1.0.6 which, I think, is compatible with Java 6. Snow Leopard is about 5 years old. Apple usually provides OS support for hardware up to 5 years old. The Windows installer will optionally install Java for you if it isn’t present and the Macintosh includes Java by default. A note to Mac OS X users: If you are running OS X Lion v10.7.5 or higher, you may receive a “damaged file” warning upon trying to run the Juxta installer.
See the Mac OS X Platform Install FAQ for general information about installing JDK 7 on Mac OS X.
- Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
- Administrator privileges.
Note that installing the JDK on a Mac 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.
JDK 7 Installation Instructions
Installation of the 64-bit JDK on Mac Platforms
When you download 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:
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.
3. 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.
4. The Install app displays the Introduction window. Click Continue.
4a. Note that, 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.
5. The Installation Type window appears. Click Install.
6. A window appears which says 'Installer is trying to install new software. Type your password to allow this.' Enter the Administrator login and password and click Install Software.
7. The software is installed and a confirmation window appears. Click the ReadMe 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
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.
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 7u6, you will see a string that includes the text 1.7.0_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.
Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*
For example, to uninstall 7u6:
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.
*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.
This article explains how to install Java 6 32bit on Mac OSX 10.10 Yosemite.
Java 6 32bit is required when using the 32bit installer for PDF Studio – a powerful, low cost Adobe® Acrobat® alternative for Mac OSX. Note that the 32bit installer is no longer the recommended installer. The new recommended installer for PDF Studio is 64bit and does no longer require Java 6.
Steps to install Java 6 If you wish to continue with the old / original installer
Q: I upgraded my mac to OSX 10.10 Yosemite & 10.11 El Capitan and I am having trouble opening PDF Studio. I receive the message: “To open “PDF Studio 9” you need to install the legacy Java SE 6 runtime.” How can I fix this?
A: Like other applications such as Dreamweaver or Creative Suite, PDF Studio requires Java 6 in order to run. During the upgrade process to Mac OS X 10.10 Yosemite or 10.11 El Capitan, Java may be uninstalled from your system. In order to reinstall and run PDF Studio you will need to install the Java 6 Runtime again. You may receive a dialog that will direct you to the site where you can download the Java 6 Runtime. Once installed you can proceed as normal with installing and using PDF Studio. You can follow the instructions below to complete the Java 6 installation.
Installing Java SE 6 Runtime
- Click on the “More Info…” button. The “More Info” button may be broken on some Yosemite minor versions. If so, go to the Mac Support site (support.apple.com/kb/DL1572) to download Java 6.
- Click on the Download button on the Mac support page
- This will begin downloading the Java installer. You can see the current status of the download on your dock.
- Once the download is complete, click on the downloads icon on the dock to open the download folder. Then click on the file labeled JavaForOSX2014-001.dmg to open the download.
- Then double click on the JavaForOSX.pkg file to open the Java 6 installer
- Follow the installation instructions to complete installing Java 6 on your system
- Once the installation is complete you can proceed as normal with installing and/or using PDF Studio. In some cases, you may need to reinstall PDF Studio as well due to the way that the Mac OSX 10.10 upgrade rearanges the files on the system.
