You ask Siri something it cannot answer, expect it to pass the question to ChatGPT, and instead get a shrug. The culprit is almost always a single switch buried in System Settings. Siri won't send questions to ChatGPT when the Extensions toggle for ChatGPT is off, and flipping it back on restores the handoff straight away.
Quick Answer
Open System Settings, head to the Apple Intelligence and Siri pane, then into Extensions, then ChatGPT, and confirm it is enabled. Apple Intelligence itself must already be switched on, because the ChatGPT extension path does not appear until it is.
The Exact Path To Check
On a Mac running a current macOS version, the toggle lives in a specific spot:
- Launch System Settings from the Dock or the Apple menu.
- Scroll to Apple Intelligence and Siri and open that pane.
- Open the Extensions section.
- Select ChatGPT.
- Make sure the main enable switch is on.
If ChatGPT does not appear as an option at all, Apple Intelligence is not yet active on the machine. Switch that on first, let it finish its initial setup, then return to Extensions and the ChatGPT entry will be there.
Why The Handoff Stops Working
The ChatGPT integration is an optional extension layered on top of Apple Intelligence, not a core part of Siri. Apple keeps it behind its own toggle so that questions only leave the device for ChatGPT when you have explicitly allowed it. That design is good for privacy, but it means a single setting change, a macOS update that resets preferences, or a fresh profile can quietly switch the bridge off.
A second common cause is the confirmation prompt. By default the system can be set to ask before sending a request to ChatGPT. If you previously declined that prompt or set it to always ask, Siri may appear to do nothing while it waits for a confirmation you did not notice. Check the same Extensions panel for a "Confirm ChatGPT Requests" option and adjust it to suit how hands-free you want the handoff to be.
If The Toggle Is On But It Still Fails
When the switch is already enabled and Siri still refuses to route questions, work through these:
- Check your internet connection. ChatGPT requests need a live connection. Siri's on-device answers work offline, but the handoff does not.
- Confirm the question actually needs ChatGPT. Siri handles many requests itself and only escalates broader or open-ended questions. Ask something clearly conversational to force the handoff.
- Restart the Mac. A reboot clears a stuck Apple Intelligence service more reliably than toggling settings.
- Update macOS. Early releases of the feature had handoff bugs that later point updates fixed.

Frequently Asked Questions
Do I need a ChatGPT account for this to work?
No. The basic ChatGPT integration works without signing in, using a free tier. Signing in with a ChatGPT account links your usage and unlocks higher limits, but the Siri handoff functions without an account.
Why does ChatGPT not appear in my Extensions at all?
Apple Intelligence is not switched on. The ChatGPT extension only becomes visible once Apple Intelligence is active and has finished its setup. Enable it first, then return to the Extensions panel.
Does this drain extra battery or send my data somewhere?
Routing a question to ChatGPT sends only that request, and only when you allow it. Apple obscures your IP and does not store the requests by default. Battery impact is negligible for occasional use.
Will the same fix work on iPhone and iPad?
The principle is identical, though the menu path differs slightly. On iOS and iPadOS you find the same ChatGPT extension toggle under Settings, Apple Intelligence and Siri. The Mac path described here is specific to macOS.
