I turned it all off as even to this day, I use obsolete kit. My newest Mac is a 2010 MacBook Pro, running dosdude1's unsupported Mojave, as I require the 32-bit support for my ancient copy of Photoshop CS3. Siri was a non-starter and I just brought that habit forward when I got my iPhone. I wouldn't say it's being a Luddite so much as it is making my machines run as quickly as they can with the OSes I installed. Gotta cut the telemetry and cloud shit out as much as possible.
