I have a Macbook Air and use it for development my WordPress products. On that Macbook, I usually install a bundle of software like Google Chrome, Firefox, FileZilla, Flux, … and a lot of development tools like Valet, PHP7.1, Composer, MariaDB, NodeJS, … It has been working fine until I want to remove them. Sadly there’s no official way to remove them completely. I tried some utility to help but it can’t work for some development tools (removing NodeJS is a nightmare!). So I searched for a better way to manage my software on Mac and I found Homebrew! It is a great tool and you should try it right now.
