The latest versions of MacOS Sequoia make it easier than ever to use Type to Siri, but many Mac users are finding themselves accidentally triggering the ‘Type to Siri’ feature.
There is no direct toggle to disable Type to Siri in MacOS Sequoia.
One option is to disable Siri in general, which will also disable Type to Siri.
Another option is to change the keyboard shortcut for Type to Siri to something obscure, making it less likely to be accidentally triggered.
