Introduction: Cocoa, the powerful framework for building macOS applications, provides developers with a rich set of tools and libraries to create stunning, feature-rich software. While traditionally used with Objective-C and Swift, Cocoa can also be leveraged with Python, opening up a world of possibilities for developers who prefer Python’s simplicity and versatility. In this guide, we’ll delve into how you can harness the power of Cocoa API with Python to build native macOS applications effortlessly.

In the intricate ecosystem of macOS, delving into system-level functionalities often reveals hidden treasures. Among these treasures is the ability to retrieve the physical addresses of network interfaces using IOKit, a powerful framework for hardware interaction. For developers and system administrators navigating the complexities of network management, understanding this process can be invaluable. In this blog post, we’ll embark on a journey to uncover the method of obtaining network physical addresses on macOS using IOKit, with a focus on Objective-C.

Introduction: When developing applications on macOS, it’s common to need to retrieve information about files, such as their size. Whether you’re building a file management utility or implementing a feature that requires knowing the size of a file, Cocoa provides convenient APIs to accomplish this task. In this guide, we’ll explore how to get the file size using Cocoa API on macOS. Using Cocoa API: Objective-C and Swift developers can leverage Cocoa APIs to interact with files and retrieve their properties, including size.
