Apple Silicon Macs: Why Apple Ditched Intel Chips

Yes. Apple phased Intel processors out of its Mac laptops and now uses its own Apple silicon chips, beginning the transition in 2020. The change replaced Intel-based Mac models with Macs built around Apple-designed systems on a chip, while macOS continued to support older Intel computers for a period of time.

When Apple moved away from Intel

Apple announced its move to Apple silicon at its developer conference in June 2020. The first Macs with the M1 chip arrived later that year, including the MacBook Air, 13-inch MacBook Pro and Mac mini. Apple said at the time that it expected the transition to take about two years; it was substantially completed across the Mac lineup by 2023, when the company introduced M3-based Macs.

This was a change in the processor architecture, not a decision to stop making laptops or stop using macOS. Earlier Mac laptops relied on Intel x86 processors. Apple silicon uses the Arm architecture, which Apple had already used in its iPhone and iPad chips. The chips are designed by Apple, while manufacturing is carried out by external semiconductor foundries.

“Ditch Intel” is therefore a useful shorthand, but it does not mean every existing Mac suddenly stopped working. Intel Macs remain in use, and their software compatibility depends on the macOS version and the individual app.

Why Apple designed its own chips

Apple’s stated reasons for the transition included improving performance and power efficiency, and allowing closer integration between hardware and software. With its own chip designs, Apple can coordinate the processor, graphics, media engines and other components with macOS and its apps rather than relying on a processor roadmap set by another company.

Power efficiency matters especially in laptops. A chip that can complete work using less energy can help a computer run longer on battery or deliver more performance within a laptop’s thermal limits. The results vary by model and workload: video editing, gaming, web browsing and sustained computing do not place the same demands on a machine.

Apple silicon also uses a system-on-a-chip design. Instead of treating the CPU, graphics processor and memory system as wholly separate components, an Apple chip integrates several computing functions into one package. Many models use unified memory, which the CPU and GPU can access. This can reduce some data transfers, but the memory is not a user-upgradable pool: buyers generally need to choose enough when configuring the Mac.

How Apple silicon works with Mac software

Apps made for Apple silicon can run natively, meaning they are built for the newer architecture rather than translated from Intel instructions. Apple’s development tools let app makers create versions that support both Intel and Apple silicon Macs during a transition, though the availability of a native version depends on the app’s developer.

For many Intel Mac apps that have not been updated, macOS can use Rosetta 2, Apple’s translation technology. It translates compatible software so it can run on Apple silicon. Translation is useful, but it is not a guarantee that every Intel program, plug-in or device driver will work. Compatibility also depends on the app’s age, how it was built and whether it relies on low-level system components.

Some Intel-based workflows need particular care. A person using older audio plug-ins, specialist hardware, virtual machines or software that depends on Intel-specific features should check with the developer or equipment maker before switching. Rosetta is not a replacement for every kind of system extension, and a program may need an update or an alternative.

What changed for MacBook buyers

For someone choosing a MacBook today, the practical choice is usually among Apple silicon models, not between a new Intel Mac and a new Apple chip. Model generations and configurations differ in CPU and GPU capability, memory, ports, screen size, cooling and battery characteristics. The best fit depends on what the laptop must do, rather than the chip name alone.

• Everyday use: Browsing, documents, video calls and streaming generally do not require the highest-tier chip. Memory and storage choices still matter for how comfortably the computer handles a person’s workload.
• Creative work: Photo, video and audio applications may benefit from stronger graphics or dedicated media capabilities, but confirm that important apps and plug-ins support the Mac’s architecture.
• Long, demanding workloads: Compare the specific MacBook models, since cooling and sustained performance can differ even when chips share a family name.
• Memory and storage: Apple silicon MacBook memory is generally integrated and not a routine later upgrade. Estimate what projects and applications require before buying; external storage can expand file space, but it does not add system memory.

There is no single chip generation that is automatically right for everyone. Check the exact model’s specifications and the software requirements for work you cannot easily change. If you already own an Intel Mac that meets your needs, the transition alone is not a reason it must be replaced.

What happens to Intel Macs and older apps

Intel Macs continue to run the macOS versions compatible with their hardware, but Apple’s software support changes over time. A particular Intel model may not support the newest macOS release, and apps may eventually stop supporting older system versions or Intel architectures. Check Apple’s compatibility information for the exact Mac model and the requirements published by each app developer.

Apple’s transition also affects developers. They may maintain separate builds, use a universal app that supports both architectures, or discontinue support for older systems. An app’s presence in the Mac App Store does not by itself prove that every feature or connected device works on every Mac.

Before replacing an Intel Mac, list essential applications and peripherals, then verify compatibility directly. For a business or school, also check centrally managed software and any specialist tools. Keeping a working Intel Mac for a legacy task can be reasonable if its software and security needs remain appropriately supported.

Common misconceptions about the switch

• “Intel Macs stopped working.” No. Existing machines continue to operate, subject to their hardware condition and software support.
• “Every old app runs perfectly through Rosetta.” No. Many compatible apps do, but older utilities, drivers, plug-ins and specialized software can have limitations.
• “Apple silicon is just a faster Intel chip.” It is a different processor architecture and system design. Performance depends on the specific chip, computer and task.
• “Unified memory means it can be upgraded later.” Usually not in MacBooks. Choose a suitable memory configuration at purchase.

The central point is that Apple changed the platform powering its Macs, not the basic role of the MacBook. For most buyers, the main questions are whether their required software works, what performance they need and which configuration will last comfortably through their expected use.

Frequently Asked Questions

Does Apple still make Intel MacBooks?
Apple’s current MacBook lineup uses Apple silicon rather than Intel processors. Intel MacBooks are older models that may still be used or found through resale channels.

When did Apple start using its own Mac chips?
The first Apple silicon Macs, powered by M1, were introduced in 2020. Apple expanded the transition across the Mac lineup over the following years.

Can an Intel Mac run Apple silicon apps?
An app must include an Intel-compatible version to run on an Intel Mac. Universal apps can support both architectures, but an Apple-silicon-only app will not run natively on Intel hardware.

Can Apple silicon Macs run Intel apps?
Many compatible Intel apps can run through Rosetta 2, but not all software or hardware-dependent tools are supported. Check with the app or device maker for critical workflows.

Should I replace my Intel Mac?
Not solely because Apple changed processors. Consider replacement if your Mac no longer meets your performance, compatibility, battery or software-support needs.
