darktable has been software of my choice for raw photo development for quite some time now, I’ve occasionally submitted bug reports and patches and kept an eye on current development by using git master version. My main operating system is Linux, which is the priority target of darktable support, but recently I bought MacBook Air to take with me on trips and such. Also my current project at work consists of porting a library to OS X, so this presented to me as a great opportunity to contribute to one of my favorite open-source projects and make darktable work reliably on Macs. Some work has already been done in the past, there’s even a package of an old darktable version for OS X, but of course I was interested in bringing the latest darktable experience to OS X.
