Obtaining the CASA Release

Supported Operating Systems


The latest CASA release 4.4.0 is available for the following operating systems:

  • Linux
    • Red Hat 6.6 and 5.11 (64-bit)
  • Mac OS X
    • OS X 10.10 (Yosemite; 64-bit)
    • OS X 10.9 (Mavericks; 64-bit)
CASA may also work on other flavors of Linux. The list above covers those operating systems that we run regular tests on. For Ubuntu users we recommend the Red Hat 6 version. Running CASA 4.4 on OS X 10.8 (or earlier) is not supported, and any such attempt should be regarded as experimental.

OS X users should be aware that it may be necessary to temporarily bypass Apple's Gatekeeper security system in order to run CASA for the first time after downloading it. This can be accomplished by using "Ctrl+click" on the downloaded application file and selecting "Open" from the contextual menu. More details may be found here.



Downloads


Please follow these links for downloading the code for your specific operating system and for the installation instructions.

We also provide links to intermediate, Stable versions, which pave the way for the next, following release. They have additional functionality over the current release but Stables are not as rigorously tested as the release and they likely contain developments that are not yet complete. All available documentation is only for the release, so Stable may behave somewhat differently from what is currently documented.

The latest CASA release is 4.4.0.
