Open ICNS File

MacOS X is the name of the operating system developed by Apple for the line of computers created by the same company.

MacOS itself is not just an operating system, but a family of systems that have evolved through different versions over time.

The main characteristic of the Mac operating system is that it is designed to work optimally on Apple computers, practically exclusively.

With this, Apple guarantees 100% compatibility of the systems developed.

The ICNS file stores one or more images, in PNG format supporting 1-bit and 8-bit alpha channels.

ICNS files are used to display the application icon in the Mac OS X finder and OS X dock.

The ICNS files should normally be located inside the directory:

Contents/Resources/

Inside the application package.
