Quick answer: yes — and for longer than you probably think. At WWDC in June 2026, Apple confirmed that every M1 Mac runs macOS 27 "Golden Gate," the release shipping this fall. A 2020 M1 MacBook Air will still be on the newest version of macOS heading into late 2027 at minimum. Based on Apple's long-running support pattern, we estimate M1 Macs keep getting major macOS upgrades until around 2028, with security updates continuing for roughly two years after that — call it 2030. If you bought (or are about to buy) a refurbished M1 MacBook Air for $450, you are not buying a dead end. You are buying years.
What Apple just confirmed at WWDC 2026
In June 2026 Apple announced macOS 27, nicknamed Golden Gate, and published the official compatibility list. The rule is simple: if your Mac has an M1 chip or newer, it is supported. That covers:
- MacBook Air (M1, 2020) and later
- MacBook Pro (M1, 2020) and later
- iMac (M1, 2021) and later
- Mac Mini (M1, 2020) and later
- Mac Studio (2022) and later
- Mac Pro (2023) and later
The Macs that did get cut this year are all Intel models. macOS 26 "Tahoe" was the last version to run on any Intel Mac, and Apple has said Intel machines will receive security patches through 2029 — but no new features, ever. If you are choosing between a cheap Intel MacBook and an M1, that decision has now been made for you (more on that below).
Golden Gate's developer beta is already out, the public beta arrives in July, and the full release — a free upgrade — is expected in October 2026.
The realistic timeline, chip by chip
Apple never announces an end-of-support date in advance, so anything past the current confirmed release is an estimate. Here is the honest version, based on how Apple has actually treated Macs for the last decade: roughly 7 to 8 years of major macOS upgrades per model, followed by about two more years of security updates.
| Chip | First sold | Confirmed today | Estimated last major macOS | Estimated security updates until |
|---|---|---|---|---|
| M1 | Late 2020 | macOS 27 (fall 2026) | Around 2028 | Around 2030 |
| M2 | Mid 2022 | macOS 27 | 2029–2030 | 2031–2032 |
| M3 | Late 2023 | macOS 27 | 2030–2031 | 2032–2033 |
| Intel (last models, 2020) | — | macOS 26 Tahoe is final | Already ended | 2029 (stated by Apple) |
Two things are worth noticing in that table. First, even the oldest M1 Macs have a confirmed newest-macOS life into late 2027, because macOS 27 remains the current release until fall 2027 and Apple patches the current release continuously. Second, Apple Silicon may age better than the estimates imply: every Mac Apple sells today shares the same core architecture as the M1, which makes it far cheaper for Apple — and for every app developer — to keep older chips supported than it ever was in the Intel era.
How Apple decides when a Mac stops getting updates
Apple has never published a formal policy, but the historical pattern is remarkably consistent. A Mac model typically receives new versions of macOS for 7 to 8 years counted from when Apple stopped selling it, not from when it launched. That detail matters for the M1 Air: Apple sold it new until 2024, which is part of why we lean toward the optimistic end of the estimate.
After the final major version, Apple keeps shipping security updates to the two previous macOS releases. In practice that means a Mac gets about two years of patches after its last big upgrade. The Intel cutoff announced this year follows the same playbook: Tahoe is their final version, and patches run through 2029.
The wildcard in your Mac's favor is the architecture transition. In the Intel days, Apple had to maintain drivers and builds for dozens of chip and GPU combinations, and cutting old models saved real engineering money. Today an M1 and an M4 are siblings. Dropping the M1 early would save Apple very little, and Golden Gate's compatibility list proves the point: six-year-old M1 machines made the cut while four-year-newer Intel configurations did not.
What actually happens when the updates stop
Your Mac does not brick itself the day support ends. Here is the realistic decay curve:
- Years 0–2 after the last major update: Apple still ships security patches. Day-to-day use is unchanged and safe.
- Years 2–4: Patches end, but major browsers historically keep supporting older macOS versions for a while after Apple moves on — and the browser is the main security surface for most people. Some new app versions start requiring a newer macOS.
- Year 4 and beyond: Banking apps, video-call tools, and cloud clients raise their minimums. The machine still works fine offline or for basics, but it is time to be off it for anything sensitive.
Practical rule: plan your replacement one to two years after the final major update if the Mac is your daily online machine. For an M1 bought today, that decision point is likely around 2029 — years away.
Buying used? Match the price to the runway
This is the math that matters when you buy refurbished. Every machine below is in stock, Luxury Certified, and covered by our 1-year warranty with a 30-day money-back guarantee, free shipping, and a compatible charger in the box.
| Mac | Price | Update runway (est.) | Who it fits |
|---|---|---|---|
| MacBook Air 13" M1 (2020) | $450 | Major updates to ~2028, security to ~2030 | Best dollars-per-year on the used market. Email, school, browsing, office work. |
| MacBook Air 13" M2 (2022) | $549 | ~2029–2030, security to ~2032 | Two extra estimated years for $99 more — the value sweet spot. |
| Mac Mini M2 (2023) | $599 | ~2029–2030, security to ~2032 | Desktop pick if you already own a monitor. |
| iMac 24" M1 (2021) | $749 | Major updates to ~2028, security to ~2030 | All-in-one family desktop with a gorgeous 4.5K screen. |
| MacBook Air 13" M3 (2024) | $849 | ~2030–2031, security to ~2033 | Longest laptop runway under $1,000. |
| MacBook Pro 14" M1 Pro (2021) | $879 | Major updates to ~2028, security to ~2030 | Pro-grade screen, speakers, and ports; still a workstation. |
| MacBook Pro 14" M3 Pro · 18GB (2023) | $1,399 | ~2030–2031, security to ~2033 | The full-AI pick — see the caveat below. |
One honest caveat about the new AI features. Every Mac in that table runs macOS 27 Golden Gate. But Apple gated the advanced on-device Siri AI capabilities — the local models and custom voice — behind an M3 chip or newer with at least 16GB of RAM. That means M1 and M2 machines, and even an 8GB M3 Air, get the release without the full AI stack. If those features matter to you, the one machine in our lineup that clears the bar is the MacBook Pro 14" M3 Pro with 18GB at $1,399. If they do not — and for most buyers they are a curiosity, not a requirement — the $450 M1 Air remains the value king.
The one Mac you should not buy for longevity
Any Intel MacBook, at any price. With Golden Gate, Apple made it official: no Intel Mac will ever receive a new version of macOS again. A $300 Intel MacBook Pro is not a bargain — it is a machine already past its final major update, coasting on security patches that end in 2029. The used market has not fully repriced this yet, so Intel machines can look temptingly cheap next to a $450 M1. Do not take the bait; the M1 is confirmed for the newest macOS and the Intel machine never will be. We walk through the full comparison in Apple Silicon vs Intel: which should you buy used.

Frequently asked questions
Will my M1 Mac get macOS 27 Golden Gate?
Yes. Apple confirmed at WWDC 2026 that every M1 Mac and newer runs macOS 27, shipping in fall 2026 — including the 2020 M1 MacBook Air and MacBook Pro, the 2021 M1 iMac, and the M1 Mac Mini.
How many years of macOS updates does an M1 Mac have left in 2026?
Confirmed: the newest macOS into late 2027. Estimated: major upgrades until around 2028 and security updates to about 2030, based on Apple's consistent 7-to-8-year support pattern.
What happens when a Mac stops getting macOS updates?
Nothing dramatic. Apple ships security patches for roughly two more years, browsers support older macOS versions for several years beyond that, and apps raise their requirements gradually. Plan a replacement one to two years after the final major update if you use the Mac online daily.
Do M1 Macs get the new Siri AI features in macOS 27?
They get macOS 27 and most of its features, but the advanced on-device Siri AI requires an M3 or newer with at least 16GB of RAM.
Is a used M1 MacBook Air still worth buying in 2026?
Yes. At $450 refurbished with a confirmed macOS 27 runway and estimated security updates to about 2030, it works out to roughly four more years of safe use for less than half the price of a new entry-level MacBook.
