So I am looking for advice insights from some of the more advanced mac users here. The story: --- I am a recent migrant to the mac world from Linux, predominantly working in the programming / computational fluids side of science. As some of you may know, one of the beauties of linux is the ability to distribute preconfigured builds (for example CAELinux which comes preinstalled with an entire engineering tool kit). After playing around with my mac's, I've started dabbling in the way which time machine/migration assistant work, and they appear to be possibilities for doing such things as distributing preconfigured packages in bulk. This was a very useful feature in linux, since our entire lab/workforce was able to have all utilities installed and preconfigured from scratch without the need to manually go through installing them. The concept: --- Create a "time machine backup" that contains preconfigured/setup builds of tools like gfortran/MPI/VisIt/OpenFOAM/etcetera (all open source software similar to CAELinux) as well as all their dependencies. Then use migration assistant to install all these on a system in a single step. Perhaps start something like the equivalent of CAELinux but for OSx Now obviously said distribution would be void of any paid or licensed software, in fact a majority of the packages I am considering are linux ports which many of us are starting to use on macs (but are sometimes incredibly difficult to get working/configured properly) The questions: --- Am I crazy? Is something like this feasible? Could you think of better alternatives of doing such a thing? Do you want to join me on my crazy project?
