TL;DR
Apple has announced that macOS 27, the next major version of its desktop operating system, will require at least an M1 chip to run, officially ending support for all Intel-based Macs. This marks the final chapter of Apple's transition away from Intel processors, a move that began in 2020 and has now reached its definitive conclusion with the forthcoming release in late 2026.
What Happened
On Monday, June 8, 2026, Apple confirmed that macOS 27 will be the first version of its operating system to require Apple Silicon, specifically an M1 chip or later, completely cutting off Intel Macs from future software updates. The announcement, reported by Ars Technica, signals the formal end of an era that began with the first Intel Macs in 2006 and the start of the Apple Silicon transition in 2020.
Key Facts
- macOS 27 will require at least an M1 chip, meaning no Intel-based Macs—from the 2006 Core Duo to the 2023 Mac Pro with Intel Xeon—will be able to run it.
- The transition from Intel began on November 10, 2020, when Apple announced the M1 chip; the last Intel Macs were sold in early 2023, including the Mac Pro and Mac mini.
- Apple shipped approximately 2.5 million Intel Macs in 2024, down from 18 million in 2020, as the installed base rapidly shifted to Apple Silicon.
- The move affects an estimated 15–20 million Intel Macs still in active use globally, according to IDC estimates from Q1 2026.
- macOS 27 is expected to ship in October 2026, following the typical fall release schedule for major macOS versions.
- Apple first dropped support for 32-bit Intel apps in macOS Catalina (2019) and later phased out OpenGL and OpenCL in macOS Mojave (2018).
- The M1 chip was first introduced in the MacBook Air, MacBook Pro, and Mac mini in November 2020; the latest M4 series chips power current Macs as of 2026.
Breaking It Down
The decision to require Apple Silicon for macOS 27 is not a surprise—Apple has been telegraphing this move for years. The company stopped selling new Intel Macs in early 2023, and subsequent macOS versions (Ventura, Sonoma, Sequoia) progressively added features that relied on the Neural Engine and unified memory architecture of Apple Silicon. By 2025, macOS 26 already required an M1 chip for certain AI features like Live Speech and on-device Siri processing. This final cut is the logical endpoint of a transition that Apple CEO Tim Cook called a "historic day for the Mac" in 2020.
Over 80% of all Macs sold in 2025 were Apple Silicon models, according to Gartner, meaning the Intel Mac base has shrunk to a minority of users—but one that still numbers in the tens of millions.
The practical impact for Intel Mac owners is severe. They will be locked out of all future macOS security updates, new features, and app compatibility that requires the latest OS. While some third-party apps may continue to support Intel Macs for a year or two, developers will rapidly shift focus to Apple Silicon-only builds. Adobe, Microsoft, and Google have already released Apple Silicon-native versions of their flagship apps—Photoshop, Office, and Chrome—and are likely to drop Intel support within 12–18 months of macOS 27's release.
The hardware implications are also significant. Intel Macs from 2019–2023—including the 2019 Mac Pro (starting at $5,999) and the 2020 Intel MacBook Air—will become effectively obsolete for new software. Users who invested in these machines face a forced upgrade cycle, though the M4 MacBook Air (starting at $1,099 in 2026) offers a dramatically faster experience. Apple's trade-in values for Intel Macs have already dropped by 40–60% since 2024, according to SellCell, reflecting the market's anticipation of this cutoff.
What Comes Next
The immediate consequence is a wave of Intel Mac users needing to upgrade. Apple will likely offer enhanced trade-in promotions and financing options to ease the transition, similar to the $200–$500 trade-in bonuses offered during the initial M1 launch. However, the pace of adoption will be driven by the specific needs of users—those running legacy Intel-only software may delay, while others will embrace the performance gains of Apple Silicon.
- macOS 27 public beta is expected in July 2026, giving developers and early adopters a first look; the final release will likely arrive in October 2026.
- Apple may release a final macOS 26 security update in late 2027 for Intel Macs, but this is not guaranteed—the company typically supports the previous two major OS versions for security patches.
- Third-party developers will announce their own Intel Mac support timelines; Adobe is expected to drop Intel support for Creative Cloud by mid-2027.
- Intel Mac resale values will collapse further, with Swappa and eBay data suggesting prices could fall by an additional 30–50% within six months of macOS 27's release.
The Bigger Picture
This move is the final milestone in Apple's Silicon Independence strategy, which has seen the company design its own processors for iPhones (A-series since 2010), iPads (A-series since 2010), and now Macs (M-series since 2020). By controlling both hardware and software, Apple achieves tighter integration, better performance per watt, and a unified architecture across its product lineup. This strategy has already yielded 2–3x performance gains over the Intel Macs they replaced, according to Apple's benchmarks, and has enabled features like unified memory (up to 192GB in the M4 Ultra) and on-device AI that Intel Macs cannot match.
The broader trend is Platform Homogenization across the tech industry. Microsoft is moving toward Arm-based Windows laptops with Qualcomm Snapdragon X chips, while Google has long used its own Tensor chips in Pixel devices. Apple's decision to cut off Intel Macs entirely accelerates this shift, forcing the entire Mac ecosystem—from developers to accessory makers—to standardize on Apple Silicon. This creates a virtuous cycle: more optimized apps, better performance, and longer battery life, but at the cost of user choice and backward compatibility.
Key Takeaways
- [End of Intel Era]: macOS 27 marks the definitive end of Intel-based Macs, requiring at least an M1 chip to run.
- [Forced Upgrade Cycle]: An estimated 15–20 million Intel Macs still in use will be locked out of future updates, driving a massive upgrade wave.
- [Performance Gains]: Apple Silicon offers 2–3x performance over Intel Macs, but at the cost of user choice and backward compatibility.
- [Industry Trend]: Apple's move mirrors broader industry shifts toward custom silicon and platform homogenization across PCs and mobile devices.
