FWIW, I clicked “skip” on a popup to set up apple intelligence and I didn’t see it again.
Of course this might change in future. And Mac OS has other popups where there is no “skip” and only “remind me later”.
I enabled it and it never bothers me. Writing tools exist, but aren’t really shoved in my face. Photos an extra tool to remove stuff from images.
I don’t use it often, but occasionally use the proofread option. Other than that, it stays out of my way.
That's more or less my experience with Copilot on Windows.
Not technically under the umbrella of Apple Intelligence, but you might be surprised to find out what photoanalysisd is doing.
