Was ich nicht wusste ist, dass dies auch die "normale" Suche im Finder betrifft. Ist aber irgendwie auch dämlich, oder?

Siri learns how you use your devices in order to personalise your experience. Using information stored on your device, such as your Safari browsing history, emails, messages and contacts, as well as information contributed by other installed apps, Siri can provide suggestions in Spotlight, Look Up, News, Photos Memories and more using local, on-device processing. You can see the full list of features that Siri personalises in the Siri section of System Preferences, under Siri Suggestions & Privacy.

Personalisation is synced across your devices with end-to-end encryption

Siri securely syncs this information between your devices to make your experience consistent on all of them. This sync is done using end-to-end encryption.

To make suggestions and search results more relevant, some information is sent to Apple and not associated with you

In some cases, such as when you use Siri Suggestions in Spotlight, Look Up or Safari, generalised topics of interest that Siri has learned may be sent to Apple to make your searches more relevant. These topics of interest (for example, cooking or football) will help to give you more relevant search results, and we use privacy-friendly techniques to disassociate these topics of interest from you.

You have choice and control

If you do not want Siri Suggestions to send your information to Apple, you can turn off Siri Suggestions. You may do so under System Preferences — select Spotlight and deselect the tickboxes Spotlight Suggestions and Spotlight Suggestions in Lookup. Safari Suggestions can be turned off in Safari. Open Safari, select the Safari menu and choose Preferences, click Search, and toggle off Include Safari Suggestions.

Ich nehmen an, darum wurde die Festplatte in den Spotlight Datenschutz gelegt?
