I'm the bureaucrat of macwrench, a wiki about all things Mac which has been around in one form or another for several decades now. It started out as a website with tips about how to fix broken Apple hardware, which has been pretty much dropped when the hardware became basically unrepairable. So about two years ago it began to morph into a wiki evolving more around software problems and became some sort of database about hidden features and frequently used tricks which could make work with macOS a little more productive and fun.
I'm still in the process of moving everything here, which will probably take a bit longer as usual since my spare time is somewhat limited and I'd like to take the opportunity to update articles and remove old and obsolete stuff in the process.
For the time being the old wiki will still be around here: macwrench.de, but new edits will most likely go in here.
And here's my home on meta.miraheze.org
