Today I set out to get Java 7 JDK running on MacOS X Mountain Lion (10.8.2). As Apple actually only installs Java 6 (1.6.x) one needs to get Java 7 from the Oracle website at the Java SE download site.

Once downloaded simply run the installer and it (should) install Java 7 properly on your system. After that, you can use the following command to make Java 7 the active version to use:

As I recall, the first time you do something that needs Java the OS will ask if you want to install it, and version 6 is what you get. According to this page, typing java -version in the Terminal is enough to trigger the prompt. For the JDK (and not the runtime), you'll need to log into developer.apple.com, search for java, and download the Java for OS X 2012-006 Developer Package. If Java is working, you should be able to see a Pink Box. Version 1.0 020213 6 of 16. Synopsis: System level disable switch does not work on Mac OSX (10.8) platform. On some systems running Mac OS X Mountain Lion (version 10.8), applying system level switch from the Java Control Panel to enable or disable Java does not work even though the correct credentials have been provided.

Now, if you use “java -version” it should actually give the output that it used Java 7.

Troubleshooting

Now the above should all be according to the book, but as things are when it comes to Java they are never “click and go”. One of the problems, I’ve had was that no application on the terminal actually picked up the Java 7 JDK. Digging around a bit showed me that the installation created sym links in the “/System/Library/Frameworks/JavaVM.framework/Versions/” directory.

As it turns out the “CurrentJDK” linked to the “old” Java 6 (1.6) installation. So, in order to point it to Java 7 I’ve had to do the following:

This immediately fixed the issue and all terminal applications worked again.

Note: I’ve had manually set the “JAVA_HOME” and “JRE_HOME” variables in the “.profile” file. With the above setting I’ve had to remove those variables in order to make it work!

Troubleshooting 2

I initially removed the Apple installed Java 6 (1.6) installation manually, I removed the directory /System/Library/Frameworks/JavaVM.framework and other Java references (yes, I know it is/was a bad idea). Just installing Java 7 did not help nor does a system reboot. Also, Apple updates did not recognise that Java was gone. Also, installing Java 6 from Apple directly (download img) did not help. In short, nothing worked anymore.

The only solution was to get Pacifist (look for it on the web). Within Pacifist load the PKG (from the Java 6 image) and install the complete package and overwrite all existing installation. This will replace all the files I accidentally removed (the important system files) and got it all up and running again.

If your machine is part of the mainstream configuration, you can discard the traditional real native partition installation method, while the use of virtual machine method described in this article, not only greatly reduce the problems encountered difficult, but also in the use of Mac OS X to get the experience is excellent the. (This tutorial configuration needs: support hardware virtualization technology (Virtualization) of the CPU. /how-to-download-netflix-shoes-on-mac.html. Current mainstream Intel Core series and AMD Athlon series CPU virtualization technology is supported, the name was Intel VT-x and AMD-V.)

Preparation

This tutorial method used by the virtual machine, provided that the machine's CPU must support hardware virtualization technology. Readers can be CPU-V or CPU-Z and other tools to test the result. Open CPU hardware virtualization technology can be turned on via the motherboard BIOS settings.

Download and install VMware Workstation VMware can go to the official website or on the ed2k network search download (recommended). Described here no longer compile.

Mac os x el capitan update download. Apple systems on Mac OS X installation disc image, use the dmg format of the original image. I recommend to search for ed2k network download (recommended), the keyword is 'Mac OS X Mountain Lion dmg' or 'Mac OS X Lion dmg'. Described here no longer compile.

Crack VMware Workstation supports Mac OS X
Here we need to use the tool 'Workstation and Fusion Mac OS X Unlocker'

VMware Workstation and complete the installation after the restart, completely unpack Unlocker compressed package to the administrator mode windows/install.cmd.

Unlocker will automatically stop VMware services, backup VMware program files, program files crack VMware, restart the VMware service and a series of operations, and will automatically end the command line window.

After the break VMware has created a virtual machine system selection dialog:

Create Mac OS X, VMware virtual machines

After Unlocker crack, start VMware Workstation normally create a virtual machine, select 'Apple Mac OS X' (depending on the Mac OS installation disk in the system, select the corresponding version of the correct version, here I use a Mac OS X Mountain Lion, version 10.8 64-bit). Creation process has the following non-default configuration:

(1) in the processor options, select 'Number of cores per processor (each processor cores)' for the two, which can induce a VMware virtual machine automatically enables advanced hardware virtualization technology.

(2) after created, first click on the 'Edit virtual machine settings', the hardware's 'Floppy' delete option is enabled in the display 'Accelerate 3D graphics'.

(3) In Virtual machine configuration, in the Advanced Settings, set the priority of the input capture 'high', and check 'Disable memory page trimming.

With a text editor (such as Notepad) to edit the virtual machine files (where the author is E:Program Files(x86)Virtual_MachinesMac OS XMac OS X.vmx), add a line at the end of the file:

This operation is used to disable the VMware virtual machine is placed on your hard disk memory mirroring prevents the virtual machine hard disk read and write operation occurs during the busy horrors.

Java 6 For Mac

Start the VMware virtual machine and install Mac OS X

Edit the virtual machine configuration 'CD / DVD' option in the 'Use ISO image file' at the choice of our Mac OS X installation disc image. (Please select the browse file dialog box when the file type, select 'All Files (*. *)', You can see the file name suffix for the dmg image file.) Confirmation is complete, start the VMware virtual machine.

Java 6 For Mac Download

Start the virtual machine, the virtual machine default boot from the CD, the Apple Logo appears after officially came to Mac OS X installation interface.

In the 'Mac OS X Utilities' select 'Disk Utility', select the first hard drive on the left and on the right select 'Erase' (the 'Format' select 'Mac OS X Extended (Journaled)'), Click the 'Erase' button to format the current drive.

After formatting the hard disk partition, back to 'Mac OS X Utilities' and click 'Install Mac OS X', enter the installation process.

Completed in a VMware virtual machine after installing Mac OS X, the first thing of course is to install VMware Tools. VMware Tools includes the VMware virtual machine 'hardware' drive, the virtual machine and the host communication between functional support.
