As I replied in else where here, I do not run any Apple Services on my Mac hardware. I do on my iDevices though, but that's a different topic. Again, I could be the edge case
But if you're being pedantic, I meant Apple SaaS requiring monthly payments or any other form of using something from Apple where I give them money outside the purchase of their hardware.
If you're talking background services as part of macOS, then you're being intentionally obtuse to the point and you know it
Not even OCSP?
