View source for Running VisIt on OS X

VisIt is used mostly in Unix environments.  Starting VisIt with OS X is straightforward as it is simply a MacOS X application bundle.

First download the [http://www.llnl.gov/visit/executables.html Darwin binary]. Binaries are provided the following platforms:
* 32-bit Intel ''(Mac 10.5 and later)''
* 64-bit Intel ''(Mac 10.6 and later)''

Click on the ''Download'' links to download the Mac application bundle stored as a 'DMG'' file.

Double-click the ''DMG'' file so your Mac opens it and exposes the VisIt application bundle. Drag the ''VisIt'' application to your desktop to copy it to your Mac.

=Running=
To run VisIt, simply double-click the ''VisIt'' application on your desktop.

When you run VisIt for the first time, you will have the option to install any network configurations for computing centers such as [https://computing.llnl.gov/?set=resources&page=OCF_resources LLNL], ORNL, LBL, and Sandia. If you do not use computing resources at those sites, you can skip the network configuration.

==Running from Terminal==
If you run VisIt from the Terminal application, you will have to reference the ''visit'' launch script within the ''VisIt.app'' application bundle. You can put that script in your path to make it easier to invoke.

Open the file called ''/Users/myname/.cshrc'' and add the following line to the end of the file (be sure to replace '''myname''' with your login name):
<code><pre>
set path=($path ~/Desktop/VisIt.app/Contents/Resources/bin)
</pre></code>

Once you have added the ''visit'' command to your path, you can simply type '''visit''' at the prompt to launch VisIt when you run from the Terminal.
