Your subjective "desirable" qualifier leaves it open for you to no-true-Scotsman away any response as "not desirable", but I can show you several. Sierra brought tabbed applications and a bunch of other end-user features [1]. As for the more technically minded, there's a new filesystem coming this year [2]. I won't defend Apple's treatment of Mac hardware recently, but the software itself does get regular updates for security, performance, and features, regardless of how one subjectively feels about them. Personally I think it's a rather visually ugly operating system and has weird quirks like awful keyboard shortcuts, and I'm mad that they removed a feature (the battery time remaining) but generally functions well for my specific use case.
