Office 2024 for Mac requires macOS 14 Sonoma or later for a fresh install. If you’re running Ventura or older, you can no longer install a fully updated copy — and from September 2025, Ventura users stopped receiving security patches. This is the complete picture: exact requirements, which Mac models qualify, and what to do if yours doesn’t.

Sonoma is the minimum. Here’s why that matters.
When Office 2024 launched in October 2024, it supported macOS Ventura, Sonoma, and Sequoia — the three most recent versions at the time. Microsoft’s policy is to support the current three macOS releases and drop the oldest when a new one ships.
Apple released macOS Sequoia in September 2024, then macOS Tahoe in 2025. As the macOS chain advanced, Ventura dropped off. From the September 2025 update (build 16.101), Ventura users stopped receiving Office updates entirely — including security patches. A fresh install via setup.office.com now delivers a Sonoma-minimum build.
As of May 2026, the three supported macOS versions are Tahoe (26), Sequoia (15), and Sonoma (14). Microsoft will drop Sonoma when the next major macOS release ships later in 2026, at which point Sequoia becomes the new minimum. The rolling three-version window keeps moving.
Which Mac models support Sonoma
Sonoma compatibility is the practical gating factor for Office 2024 new installs. Every Mac that runs Sonoma or later qualifies. The model cutoffs are as follows — sourced directly from Apple’s compatibility page.
| Model | Earliest supported | Chip | Office 2024 |
|---|---|---|---|
| MacBook Pro | 2018 | Intel / Apple Silicon | Supported |
| MacBook Air | 2018 | Intel / Apple Silicon | Supported |
| iMac | 2019 | Intel / Apple Silicon | Supported |
| iMac Pro | 2017 (only model made) | Intel Xeon | Supported |
| Mac mini | 2018 | Intel / Apple Silicon | Supported |
| Mac Studio | 2022 (all models) | Apple Silicon | Supported |
| Mac Pro | 2019 | Intel / Apple Silicon | Supported |
| MacBook Pro 2017 | — | Intel | Not supported |
| MacBook Air 2017 | — | Intel | Not supported |
| iMac 2017 / 2018 | — | Intel | Not supported |
| Mac mini 2017 | — | Intel | Not supported |
| Mac Pro 2013 | — | Intel | Not supported |
The rough rule: if your Mac is from 2018 or later (2019 for non-Pro iMac), you can run Sonoma and therefore install Office 2024 with full updates. The iMac Pro from 2017 is the one older-hardware exception — Apple included it in Sonoma support despite its age.
How to find your macOS version and Mac model
-
Click the Apple menu () in the top-left corner of your screen and select About This Mac.
-
The window shows your macOS version (e.g.
macOS Sequoia 15.4) and your Mac model (e.g.MacBook Pro (14-inch, 2023)). Both are visible without scrolling. -
If macOS is 14 or higher, you’re ready to install Office 2024. If it shows 13 (Ventura) or lower, check the table above to see if your Mac model supports an upgrade.
-
To upgrade macOS: go to System Settings → General → Software Update. If Sonoma or later is available for your machine, it will appear here.
Apple Silicon vs Intel — what Office actually feels like
Office 2024 ships as a Universal binary, meaning the same download installs natively on both Intel and Apple Silicon Macs. No Rosetta 2, no compatibility layer, no performance tax.
In practice, the difference between a 2018 Intel MacBook Pro and a 2020 M1 MacBook Air running Office is stark. Excel with a complex model — VLOOKUP across 50,000 rows, conditional formatting applied throughout — opens in under a second on M1, where the same file took three to five seconds on a 2017 Intel machine. Word’s response to large documents with track changes is similarly transformed.
Capable, not fast
Word and PowerPoint are fine for everyday use. Excel with large datasets or complex formulae can lag noticeably on 8 GB Intel machines. Fan noise under load. Battery life is the main practical limitation — expect 5–6 hours of Office work on a 2019 MacBook Pro.
Noticeably better
Office feels genuinely fast regardless of file size. 8–10 hours of Office work on M1 MacBook Air without a charger is normal. M2 and M3 add further improvements, though the jump from Intel to M1 is where most users feel the biggest difference.
If you’re on an Intel Mac from 2018–2020 and the machine is otherwise in good condition, Office 2024 will run without issues. Don’t buy a new Mac just for Office. But if you’re already thinking about upgrading your machine, the Office experience is one more argument in favour of making the move.
RAM and storage: what the minimum figures don’t tell you
Microsoft states 4 GB RAM as the minimum and 10 GB free storage for installation. Both figures are technically accurate and practically insufficient for serious use.
RAM
On a 4 GB Mac — which means an older Intel machine, since Apple Silicon Macs start at 8 GB — running Word and Outlook simultaneously alongside Safari with a handful of tabs will cause macOS to lean heavily on swap memory. You’ll feel it in response times. Office runs, but it doesn’t run well.
8 GB is the real-world minimum for comfortable use. If you have an 8 GB M1 Mac and primarily use Word and Excel, you’ll be fine. The same 8 GB on a 2019 Intel iMac running multiple apps at once will be more constrained — macOS itself is hungrier on Intel.
Storage
The 10 GB figure covers the installation. Your actual documents, autosave data, and OneDrive cache will add to that. On a Mac with 128 GB or 256 GB of storage that’s already well-used, it’s worth checking available space before installing — particularly on older Intel Macs where storage can’t be expanded.
If your Mac doesn’t support Sonoma
A Mac from 2017 or earlier (non-iMac Pro) won’t run Sonoma and therefore can’t receive the latest Office 2024 build. The honest options are limited.
Office 2021 for Mac
Runs on older macOS versions. The catch: Office 2021 for Mac loses support in October 2026 — just months away. Buying it now gives you a product with a very short remaining support window. Fine as a short-term bridge; not a long-term solution.
Office on the web
Word, Excel, and PowerPoint all run in a browser via office.com — free with a Microsoft account, no installation required. Feature-reduced compared to the desktop apps, but functional for everyday document work on any Mac with a modern browser.
The harder truth: a Mac that can’t run Sonoma is seven or more years old. If Office compatibility is the main thing keeping you from upgrading the hardware, that’s a reasonable point to make the switch. A new Mac mini starts at £599 — and Office 2024 for Mac at — on top of that still represents far better value than five years of Microsoft 365 subscriptions.
FAQ
New installs of Office 2024 for Mac require macOS 14 Sonoma or later. As of May 2026, Microsoft supports Office on macOS Tahoe (26), Sequoia (15), and Sonoma (14). Ventura support was dropped with the September 2025 update (build 16.101); Monterey was dropped earlier in 2024. If your Mac runs Sonoma, you can install and receive updates normally.
It depends on the model. The iMac Pro (2017) supports macOS Sonoma and therefore qualifies. All other 2017 Mac models — MacBook Pro, MacBook Air, iMac (non-Pro), Mac mini — do not support Sonoma and cannot receive the latest Office 2024 updates. A 2017 MacBook Pro can still run an older cached build of Office, but it won’t receive any further security updates.
Existing Office installations will continue to function on Ventura, but Microsoft stopped delivering updates — including security patches — to Ventura users from September 2025. You can’t perform a fresh install and receive a current build on Ventura; setup.office.com will deliver a Sonoma-minimum installer. If your Ventura Mac supports an upgrade to Sonoma, that’s the right move.
Yes, fully. Office 2024 is a Universal binary with native builds for M1, M2, M3, and M4 chips. No Rosetta 2 translation is required. Performance on Apple Silicon — particularly in Excel with large datasets and in PowerPoint with complex animations — is considerably better than on equivalent Intel hardware.
The official minimum is 4 GB, but 8 GB is the practical floor for comfortable everyday use. On a 4 GB Intel Mac running Word and Outlook alongside a browser, macOS will use swap memory heavily and performance will be sluggish. Apple Silicon Macs start at 8 GB, so if you’re on any M-series machine you already meet the real-world requirement. 16 GB makes a noticeable difference if you work with large Excel files regularly.
Microsoft’s stated requirement is 10 GB of available disk space. In practice the installed footprint is around 10 GB once all five apps and their components are in place. If you’re tight on space, check via Apple menu → About This Mac → Storage before starting the installation. Leave at least 15 GB free to give the installer room to work.
Yes — to activate. You redeem your product key at setup.office.com, which requires a Microsoft account sign-in. A free account works fine; you don’t need Microsoft 365. Once activated, Office runs fully offline with no ongoing sign-in required. This activation method applies to all Mac editions of Office 2024, including Word standalone.
