Macs do not respect your privacy. In comparison to windows it’s better but they still log and send every application you open to Apple.
That claim seems like it’d be trivial to fact check, and indeed does seem to be false.
Does Apple really log every app you run? A technical look

I am not ever trusting a proprietary OS, specially when it has been actively advertised as “caring about your privacy”
It is the advertising of any market differentiator or specifically when it’s for security.
