That's all I want! A not-completely-useless Siri, and performance/quality of life improvements.
MacOS is fine. For the most part it gets out of my way. However I have a laundry list of small issues that have been there since my first Mac in 2012. I wish there was a Department of Details to fix those little snags in the user experience.
I just want a Siri that doesn't trigger when my partner says "Siri set a timer for 20 minutes" on a completely different floor of the house.
The solution is obviously to switch partner.
You're obviously holding your partner the wrong way.
