No, this is not on by default. After system install at first boot it asks if you want to help improve search and it describes how your data will be handled, anonymized, etc. If you clicked on yes it is on. There is a choice to opt out.

I was on by default for me, both after the macOS 14 -> 15 upgrade and after installing macOS 15 cleanly. I wonder if they ask for consent in some regions only.

Yeah this seems to be on by default for me as well, I definitely take issue with that.

You're lying, it is on by default.

I always say no to all analytics/improvement prompts.

Both the search and photos settings were on for me in both iOS and MacOs. Completely unacceptable Apple
