The bitten apple defines it as powerful and at the same time simple, bringing new features with it based on the experience of the best professionals but designed for everyone.

Among the new features in macOS Mojave we have the Dark Mode that allows you to concentrate as much as possible on what you are doing, enhancing even the lightest colors and the smallest details. Present an interesting new feature called Pile that keeps the Desk in order by automatically gathering files of the same format. This means that you can group images, documents, spreadsheets, PDFs and so on in one place.

macOS Mojave also brings some news for Finder with it, the file manager par excellence of Apple. For example, you can now quickly search for a file based on its appearance. The new Quick View feature lets you take a quick look at the file without opening it using the default application. For example, you can apply a note to a PDF, rotate or crop an image, or cut an audio and video file without opening it with the respective software.
