I still care about macOS because it is still the most pleasant desktop environment to use, in my opinion. I love macOS's pervasive support for PDFs and macOS's font rendering. I also love the iLife suite of applications. With that being said, I've been trying out alternatives to macOS since I've been disappointed with Apple's stewardship of the Mac under Tim Cook, but I keep going back to macOS, though I haven't upgraded to Catalina yet since I still rely on some proprietary 32-bit software packages that I don't feel like repurchasing until I make a final decision about how long I'll stay on the Mac. I tried Windows 10 and I sometimes use it for work; while I can get by, the experience is just not as pleasant for me. While Windows 10 does have some nice features, including the wonderful WSL layer, I don't like the ads and the notifications to use MS services, I find the UI ugly (what's with the huge title bars in Windows 8 and Windows 10?), and the mandatory updates are annoying. I miss the days of Windows 2000, and I'm awaiting the day I can use ReactOS as a daily-driver OS. As far as Linux desktops go, I feel most productive with Cinnamon. However, I find myself missing certain macOS features and certain proprietary software tools (such as Keynote and Microsoft Office), and I also find myself missing the fit-and-finish of macOS.
Nevertheless, barring a dramatic leadership change at Apple, I see the writing on the wall regarding the future of the Mac. I don't think the Mac will disappear, but I definitely see it becoming more locked-down and more iOS like, which is a trend I don't like. I'm going to stick to macOS Mojave on my 2013 MacBook Air and my 2013 Mac Pro, which are my daily drivers. But I can see myself switching sometime around 2022 or 2023.
