Installing CASA on Mac OS
Installation
CASA for Macintosh is 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.
- Download the CASA disk image for your OS version from our download site
- Open the disk image file (if your browser does not do so automatically).
- Drag the CASA application to the Applications folder of your hard disk.
- Eject the CASA disk image.
- 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.
If you had previously installed CASA rev 8909 or later you will need to unload the dbus before the copy will work
launchctl remove org.freedesktop.dbus-session
launchctl remove org.freedesktop.dbus-system
The first time you launch the CASA application, it will prompt you to set up an alias to the casapy command. You will be taken through the process of creating several casapy symbolic links, it is advisable to do so as this will allow you to run casapy from a terminal window by typing casapy. Additionally, the viewer (casaviewer), table browser (casabrowser), plotms (casaplotms), and buildmytasks will also be available via the command line. Creating the symbolic links will require that you have administrator priviledges.
Notes:
(1) If your mac is running a 32 bit kernel and has a 64bit processor it will be able to run 64bit applications like CASA. If you have a 32bit processor, i.e. "Core Duo" then it will not.
(2)On some configurations of Mac 10.6 OS unwanted windows may
appear when a task based on matplotlib. The tasks may also throw
errors (see the help file in the dmg). The solution to this is the set
"backend: TkAgg" in your ~/.matplotlib/matplotlibrc file.
