Fix Touch Bar Volume Buttons

28.3.2019

31.1.2019
Whenever I need to accomplish a basic task that typically calls for interacting with a UI, I challenge myself to complete the task from command line. After all, most UIs are simply a mask over basic commands, especially when it comes to the operating system. Suddenly I feel like an automation...

Mac Dark Mode from Command Line

30.1.2019
One of the best professional decisions I ever made was switching to a dark text editor theme. I suffered from horrible headaches for years, partially caused by late night coding sessions with blindingly bright computer screens. Recently Apple implemented a dark OS theme which helps my eyes,...
