Ports of SAOImageDS9 for MacOS
SAOImageDS9 for the Mac Operating System is released in two ports:
as an Aqua application (the graphical user interface native to MacOS)
as an Darwin X11 application (requires XQuartz to run).
There is no operational difference between the two ports and it is just a matter of preference.
The Aqua port is installed by the normal MacOS method of downloading a disk image, double clicking on the file, and click and drag the application into the /Applications directory.
The X11 port is installed by downloading a tarball archive, unpacking the file:
% tar -xvzf darwin<os><arch>.<version>.tar.gz
and moving 2 files, ds9 and ds9.zip into a directory that is in your shell PATH variable, such as your local bin directory:
% mv ds9 ds9.zip $HOME/bin/.
General users can install the Aqua version which does not require any additional software.
If you need to use command line options, install the Darwin X11 version
SAOImageDS9 is also released for the two different kinds of processors in Mac computers: Intel processors (2020 and before) or Apple Silicon processors (2020 and after). To find out the kind of processor check "About this Mac" from the Apple menu.
MacOS Sonoma (MacOS 14) users should download the MacOS Ventura (MacOs 13) version.
IMPORTANT- READ ME
The Aqua installation for several versions may show warnings about "unknown developer" or "damaged application". If this is the case after the installation run the following command at the prompt in a Terminal window
% xattr -c /Applications/SAOImageDS9.app

PyDS9
The pyds9 module uses a Python interface to XPA to communicate with DS9. This includes not only sending data and settings to DS9, but also retrieving them into Python.
DAX
DAX, the Ds9 Analysis eXtensions, is a collection of CIAO tasks that have been integrated using DS9's analysis menu interface. DAX provides users access to many mission independent CIAO tools and applications using a simplified graphical user interface.
With DAX users can perform various image processing operations (eg adaptive and non-linear smoothing), compute net counts and fluxes, perform source detection, and even modeling and fitting of spectra and 2D images using Sherpa.
