I had to help my sister keep her 8 year old Mac going or buy a new secondhand (cheap) machine. With the options out there and with the state of Windows, I didn't even consider it.
She's ended up with her same 8 year old Mac with Ubuntu 24.04, and I've been really impressed with how it's actually great for non-technical users these days! And works really well on old hardware.
This should give her another few years of life out of the thing without worrying about software support.
What's the point of installing the app then? Just use netflix in a browser if you're going to use netflix. The only reason you even needed the stupid app was to use the download feature
