Apple Intelligence vs Charm: Which Works on Your Mac Version?

Apple Intelligence requires macOS 15 Sequoia AND an Apple Silicon chip (M1 or later) - both conditions must be true. Charm requires only macOS 14 Sonoma and works on any Mac, Intel or Apple Silicon. If you have an Intel Mac, or if you are still on macOS 14, Charm is available to you right now. Apple Intelligence is not, and never will be on Intel hardware.

Which Mac versions support Apple Intelligence?

Apple Intelligence has two requirements that both must be satisfied:

macOS version: macOS 15 Sequoia or later. Macs on Ventura (13) or Sonoma (14) cannot use Apple Intelligence regardless of chip.

Chip: Apple Silicon only - M1, M2, M3, M4, or later. Intel Macs are permanently excluded from Apple Intelligence, even if they can run macOS Sequoia.

Note that macOS Sequoia supports some Intel Mac models. Intel MacBook Pros from 2018+, iMacs from 2019+, Mac Pros from 2019+, Mac minis from 2018+, and iMac Pros from 2017+ can all run Sequoia. But running Sequoia on Intel gives zero Apple Intelligence features. The chip requirement is absolute and hardware-limited - there is no workaround, update, or setting that enables Apple Intelligence on Intel.

Approximately 35% of active Macs are Intel-based. These users - a large minority of the Mac installed base - are permanently locked out of Apple Intelligence. For this group, tools like Charm are the only available writing improvement, regardless of macOS version.

Which Mac versions support Charm?

Charm's requirements are simpler: macOS 14 Sonoma or later, on Intel or Apple Silicon. That is the complete list of conditions.

If you are on macOS 14 Sonoma with an Intel Mac: Charm works fully. Apple Intelligence does not work at all.

If you are on macOS 14 Sonoma with an M-series chip: Charm works fully. Apple Intelligence does not work (requires Sequoia).

If you are on macOS 15 Sequoia with an Intel chip: Charm works fully. Apple Intelligence does not work (requires Apple Silicon).

If you are on macOS 15 Sequoia with an M-series chip: Both Charm and Apple Intelligence work. They complement each other - Charm for real-time correction everywhere, Apple Intelligence for post-edit rewriting in native Apple apps.

Feature comparison by macOS version

Even in the one scenario where both tools are available - Sequoia on Apple Silicon - Apple Intelligence's Writing Tools only work in native Apple apps. Electron apps like Slack, VS Code, Discord, Notion, and Obsidian are excluded entirely. Charm covers all of these. 73% of top Mac productivity apps are Electron-based, which means Apple Intelligence misses the majority of where professional Mac users write every day.

Does upgrading to Sequoia give you everything you need?

Not if you primarily write in Electron apps - which most professionals do.

Upgrading an Apple Silicon Mac from Sonoma to Sequoia adds Apple Intelligence. This is a genuine improvement for writing in native Apple apps. But the workflow in Slack, VS Code, Notion, and other Electron apps is completely unchanged. Those apps remain outside Apple Intelligence's coverage regardless of macOS version.

For Intel Mac users, upgrading to Sequoia provides no writing improvements at all. The autocorrect engine is unchanged, Apple Intelligence is unavailable, and Electron app coverage is the same as always.

The approximately 40% of active Macs still running Sonoma - both Intel and Apple Silicon - also receive no Apple Intelligence benefit. For these users, Charm is available right now, on the macOS version they are already running.

The combination of Charm and Apple Intelligence on Sequoia Apple Silicon is the best possible Mac writing setup: real-time correction in every app from Charm, plus post-edit rewriting and tone adjustment in Apple apps from Apple Intelligence. Each tool fills the gaps the other leaves.

Frequently asked questions

Does Apple Intelligence work on Intel Mac with Sequoia?

No. Apple Intelligence requires both macOS 15 Sequoia AND Apple Silicon (M1 or later). Intel Macs can run Sequoia but Apple Intelligence is locked to Apple Silicon. Running Sequoia on an Intel Mac gives you zero Apple Intelligence features - the real-time autocorrect experience is identical to Sonoma.

What macOS does Charm require?

Charm requires macOS 14 Sonoma or later and works on both Intel and Apple Silicon Macs. It does not require Apple Silicon. On macOS 14 or 15, Charm provides full functionality: real-time spelling correction, grammar correction, and word prediction in every app.

Is Apple Intelligence better than Charm on supported hardware?

Apple Intelligence and Charm do different things. Apple Intelligence offers post-edit rewriting in native Apple apps on Apple Silicon. Charm provides real-time correction in every app including Electron apps. On fully supported hardware (Sequoia + Apple Silicon), using both together is the optimal setup - they complement each other rather than compete.

Can I use Charm and Apple Intelligence at the same time?

Yes. They operate independently and complement each other. Charm runs in the background providing real-time correction as you type. Apple Intelligence's Writing Tools are invoked manually on selected text. Both can be active simultaneously without conflict.

Does upgrading to macOS Sequoia improve autocorrect?

Only if you have Apple Silicon. For Apple Silicon Macs, Sequoia adds Apple Intelligence Writing Tools in native Apple apps. For Intel Macs, the autocorrect experience is essentially unchanged. In all cases, Electron apps like Slack and VS Code remain uncorrected by Apple Intelligence - that gap requires Charm.
