Having tried out Mac OS, Linux and Windows I find that they all have their advantages and disadvantages.
Linux comes with a large amount of free and quite useable software, yet can be tricky with new or exotic hardware
Mac OS is very easy to use, but the selection of programs is more limited than the two others.
Windows has as many programs as you want, yet is so commonly in use that it is a target for Virus, Trojans and other malware.

I found a neat program for making and organising notes when using linux. Zim desktop wiki easily creates linked text files in a wiki-like way, yet it is on my own machine.
The Linux version is packaged for the most common distributions There is a Windows executable, so there it is easy, too.

Enter the Mac

Mac OS X is a Unix like system, much like Linux,yet with some quirks.installing Linux programs directly is not possible, so someone has made package installers available, compiling the source code and, mostly taking care that dependencies are installed.
Macports has Zim in its repository. However the version is an ancient one that possibly will cease running in a not so far future. The version is Perl based and no longer maintained. The latest version is written in Python, and here is the thing.
Some dependencies are not readily recognised because they are not in the “expected places”.
I have been looking into it the last week, and it looks like I have found a way to get it running. I want to make sure it is reproducible, and then I intend to write in the blog how I got it running.

Update : It looks like I got the install procedure running, nor I will make an attempt to simplify the procedure.
