Best IoT Operating Systems for Mac of 2025

Contiki-NG is an open-source and cross-platform operating system that supports Next-Generation IoT devices. It is focused on reliable (secure and reliable) low power communication and standard protocols such as IPv6/6LoWPAN and 6TiSCH, RPL and CoAP. Contiki-NG includes extensive documentation, tutorials and a release cycle. It also has a well-defined development flow to facilitate the seamless integration of community contributions. Contiki-NG source code is distributed under the 3-clause BSD licence, unless otherwise stated. This license grants everyone the right of use and distribution of the code in binary or source format as long as the copyright licence is not lost in the source code.

Arm Mbed OS, an open-source IoT operating platform, is free and available for download. It includes all the features needed to create IoT products. The OS contains everything you need for smart, connected products that run on Arm Cortex M based hardware. This includes machine learning capabilities, security stacks, connectivity stacks, and drivers for sensors and other I/O devices. Arm Mbed OS was designed for the Internet of Things. It integrates with connectivity, machine-learning, networking, security stacks, and is supported by software libraries, tutorials, hardware, and examples. Mbed OS supports over 70 silicon, module and cloud partners. This allows you to optimize your developer choice. Mbed OS API allows you to keep your application code clean, portable, and easy while taking advantage security, communications, and machine learning. The integrated solution reduces development time, cost, and risk.

Raspberry Pi Imager allows you to quickly and easily install Raspberry Pi OS or other operating systems to microSD cards, which can then be used with your Raspberry Pi. Watch this 45-second video to learn how Raspberry Pi Imager installs an operating system. Install Raspberry Pi Imager on a computer that has an SD card reader. Install Raspberry Pi Imager on the computer with an SD card reader. Browse the operating systems available from Raspberry Pi and other organizations, and download them to manually install.

A kernel is the core of any embedded OS. It provides crucial task scheduling and multitasking services that ensure your application code's timing requirements can be met. You also regularly update and add new features to that code. Micrium OS is much more than a kernel. It provides a variety of modules that can be used to meet your project's requirements. Micrium OS is completely free to use on Silicon Labs EFM32 or EFR32 devices. Micrium OS can be added to your projects immediately without any licensing fees.

From simple embedded environmental sensors to advanced embedded controllers and smart watches to IoT wireless applications, there are many options. Implements configurable architecture-specific stack-overflow protection, kernel object and device driver permission tracking, and thread isolation with thread-level memory protection on x86, ARC, and ARM architectures, userspace, and memory domains. Supports combining application-specific code and a custom kernel on platforms without MMU/MPU or memory constrained devices to create a monolithic images that are loaded and executed on a system’s hardware. Both the kernel and application code are executed in a single address space.
