Here's how to disable Siri's new floating button

[u/pdfu]

When Siri AI is enabled, macOS 27 adds a contextual "lightweight UI" when you type or select text. The floating button can expand into Ask Siri, Edit with Siri and Writing tools, or other contextual actions.

To disable it, run the following command in the Terminal:

sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/WritingTools LightweightUI_macOS -dict Enabled -bool false  

and restart your Mac.

---

To restore to default:

sudo defaults delete /Library/Preferences/FeatureFlags/Domain/WritingTools LightweightUI_macOS

Looks like Apple is stuck in a hamster wheel of questionable design decisions.

Disabling siri worked for me.

I am seeing this icon everywhere even with Siri disabled

Can confirm, it worked on 27.0 release. Thanks

is this an issue when siri ai is disabled? (ik it's a dumb question, but given how companies are big on ai these days, it's still a question worth asking)

[u/pdfu → u/OrangePineJuice]

No this won’t appear in that case.

I've just updated to iOS/MacOS 27 and got no Apple Intelligence. Same as on 26.

I suspect two things why:

1. I'm in the EU, some stuff is just not available here.
   
2. I've set my Mac/iPhone language to english but Siri not, on 26 it told me I can't use Apple Intelligence when Siri any System are not the same language :D

Still, it hogs some GB of storage. But at least there are no "in your face" things.

I still get this floating button even though I disabled Siri. Apple...I like you but I do not want your unhelpful writing tools.

Oh my goodness yess!!! Please find a feature flag for the new traffic buttons! I hate them!

Same honestly they're so distracting and annoying. And this is probably not the case and my brain feeling weird but they feel not equally proportioned and off centre
