It was born as an incredibly pioneering website by providing daily tricks to the maquera community and today we can say that it is one of the reference pages - recently integrated into Macworld - of the Mac world.
They have been ten years in which they have given tips for all kinds of things, tips for a thousand problems and tons of terminal commands to improve the user experience on Mac OS X.
In short, a model site, and from here we congratulate you on those 10 years of notes on Mac OS X.
