> high DPI is an even more troublesome issue with Linux. As of right now, for me, high DPI is not worth it outside of the Apple walled garden. Actual 4K resolution works way better on Linux than it does on OS X. By default, OS X will use 2560x1440, even on a display that's capable of 3840x2160. If you try to set it to the latter on OS X in your display settings, it looks really terrible. The experience is less consistent on Linux in 3840x2160, but overall it's much better, and it's well-supported by the common applications that Linux users would use (Firefox/Chrome, terminal emulators, any GTK+ 3 or Qt 5 applications, and more).

On Fedora 26 with Wayland, high-DPI works pretty well in my experience.

  It does not. If you have e.g. QHD on a 13" laptop, then it's cool because 2x scaling works. On my 32" 4K display, it's bad because I'd need 125% or 150% scaling, not 100% or 200%.

    Fractional scaling is in the works for the next Gnome release. I've been using the former case, so that's why I said it works well for me.

OSX will happily use 3840x2160. Are you sure your limitation is not somewhere else? Maybe you ran out of available crts on the graphics card, or the display cable has it's limits, or whatever. That said, the 4K support in Fedora is nice. The only problem is with Qt4, Gtk2 and other apps using legacy toolkits.

    Right now I'm sitting behind 4K (Dell P2715Q) monitor connected to rMBP (13", 2015). What I'm supposed to miss? What exactly is not displaying correctly and I didn't notice? Also, exactly what applications do not use Cocoa? Apple had made extremely difficult to talk directly do display server, the two non-private-frameworks-without-stable-abi ways were Carbon and Cocoa. Carbon is already dead.

I use the same monitor as well. Until recently, I had the 15" version of that laptop, and now I have the latest 15" Macbook Pro. Both use 2560x1440 on the external monitor even though it's capable of 3840x2160, because that's what OS X defaults to, and every time I try increasing the resolution, I only make it a few minutes before I can't stand how terrible the experience is and end up switching back. > Also, exactly what applications do not use Cocoa? I'm saying that native Mac applications look really bad on OS X when set to 3840x2160. The UI and text don't scale consistently, and that's true both of the system-level UI and of application UI. The situation gets even worse when you're talking about applications designed for X11[0], which I could forgive, but on the other hand, those applications scale just fine on Linux. By contrast, all of this works out-of-the-box in (for example) Unity. I don't have to deal with dialog boxes that are out of proportion with the system bar, or text that's impossible to read unless I squint on some applications but perfectly readable on others. [0] We could get into a debate about whether XQuartz really counts as "cocoa" or not, but I'd rather not.
