Macwrench collects helpful tips and tricks for using macOS. It has a long history back well into the nineties and started out as wiki about tinkering and fixing broken parts of any Apple hardware. Over the years/decades it morphed into some sort of database for using macOS and Apple Software. I took over about 15 years ago during my time at university when the original maintainer - one of my fellow students - intended to abandon the project because most of the articles were already hopelessly outdated. I continue using and maintaining the wiki by occasionally adding helpful tips and updating existing ones.
