Transition from Intel to M-Series Chips

Almost all major hardware transitions in Apple’s history are outshone by the switch from Intel processors to custom. This was not just a change in suppliers, but a strategic move that allowed Apple to have complete control over all aspects of performance, design, and long-term innovation in the Mac.

The outcome changes the definition of what it means to users by laptops and desktops when it comes to battery life, efficiency, and the relationship between macOS and hardware.

Let us take a look at the reasons that prompted Apple to make this transition, the process of change, and the first Apple silicon chip: what benefits the M1 delivered straight out of the box-and what’s wrong with it.

Reasons Why Apple Left Intel

For years, Apple depended on Intel for the processors that powered MacBooks, iMacs, and Mac Pros. However, this partnership eventually started to show cracks:

• Slower innovation cycles: Intel’s delays in moving to smaller chip processes (like the 10nm and 7nm nodes) affected Mac upgrade timelines.
• Thermal inefficiencies: Intel chips consumed more power and generated more heat, limiting design flexibility in thin and light laptops like the MacBook Air.
• Limited vertical integration: Apple couldn’t fully optimize macOS or its apps for Intel processors, which weren’t designed specifically for Apple hardware.

By switching to in-house ARM-based designs, Apple could eliminate these bottlenecks and develop a tightly integrated system, something it had already done successfully with the iPhone and iPad.

Timeline of the migration

Apple officially announced its transition to Apple Silicon in June 2020 at its WWDC keynote. The migration unfolded in stages:

• November 2020: The M1 chip debuted in the MacBook Air, MacBook Pro (13-inch), and Mac Mini.
• 2021–2022: Apple gradually replaced Intel chips across more models, introducing M1 Pro, M1 Max, and M1 Ultra variants.
• By 2023: Most mainstream Macs had moved to Apple silicon, including the redesigned iMac and the high-end Mac Studio.
• 2023–2024: Apple completed the transition by introducing M2 and M3 variants, including in the Mac Pro.

This staged rollout ensured that developers had time to optimize apps for the new architecture, and it gave users a smooth transition experience without compatibility issues.
