Obtaining CASA for Macintosh Intel

Download CASA for Intel

June 14 2010 -- Release 3.0.2 (build 30.2.11761).

CASA for Macintosh is now distributed as self-contained Macintosh application.

Information about the CASA application and interaction with the UNIX shell is on this page and in the CASA for Macintosh release notes.

CASA for Macintosh is now distributed as self-contained Macintosh application.

For installation purposes, this means that you can install CASA by simply dragging the application to your hard disk. It should be as easy as copying a file.

  1. Download the CASA disk image, OSX 10.5 or
  2. Download the CASA disk image, OSX 10.6
  3. Open the disk image file (if your browser does not do so automatically).
  4. Drag the CASA application to the Applications folder of your hard disk.
  5. Eject the CASA disk image.
  6. Double-click the CASA application to run it for the first time. This ensures everything is properly updated if you had installed a previous version.

The first time you launch the CASA application, it will prompt you to set up an alias to the casapy command.

System Requirements

To install this distribution of CASA on your Macintosh, your system must meet the following requirements:

  • Macintosh Intel
  • OS X 10.5.8 or later (for OSX 10.6 you will need to install the 10.6 version of the dmg)
  • 400 MB of free disk space for the application (more space is needed for data files, of course).

Leopard (Mac OS X 10.5) and Snow Leopard (Mac OS X 10.6) Support

This build has been tested with Leopard 10.5.8. No Leopard-specific issues have been found. Installation of the 10.5 version of the CASA dmg has issues, you will need to install the 10.6 version of the dmg. Note Snow Leopard build was updated 04/27/2010.

Special Instructions for Previous CASA Mac Intel testers

CASA now installs as a self-contained, stand-alone application. Previous versions of CASA are not affected. Existing installations of MacPorts or DarwinPorts are not affected. They may co-exist on the same computer as this version of CASA.

You do not have to run any setup scripts or otherwise modify your shell environment.

However, if you wish to use this version of CASA from a shell environment, you should make sure that your PATH environment variable is set up so that the symbolic link to this version of the casapy command.

The CASA Application and the Shell

CASA for Macintosh is now distributed as self-contained Macintosh application.

For installation purposes, this means that you can install CASA by simply dragging the application to your hard disk. It should be as easy as copying a file.

Of course, CASA is not a typical Macintosh application: it is not exclusively a graphical user-interface program like Microsoft Word. Rather, CASA is an interactive data-analysis environment. Most use of CASA is through an interactive Python shell, the image viewer, or the table browser.

The CASA "application" executable, therefore, is mostly a bootstrap process that sets up a shell environment and launches the "casapy" program in a Terminal window.

The CASA application also maintains a symbolic link to its main casapy program so that you may run CASA from any shell command prompt. You don't have to double-click on the application icon each time.

More Technical Mutterings

We needed to package CASA as a Macintosh application in order to address some GUI event-loop initialization issues when a CASA graphical user interface was invoked from within the casapy Python environment. The simplification of the installation process was an extra bonus.
