From macwrench

Macwrench (reachable via as well) 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- one of my fellow students - intended to abandon the project because most of the articles were already hopelessly outdated.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.

It used to be german only, but in the last couple of years I began to mostly use English for such things. I try to translate the other articles one at a time whenever I have some spare time, but for the time being this will result in a funny mixture of these two languages. Hagbard (talk)
