A lot of macOS/iOS was written from scratch, though: Core Graphics (vs. Cairo and FreeType), Core Animation, Core Text (vs. pango), WindowServer (vs. X11), UIKit (vs. Cocoa), IOKit (vs. the native BSD driver framework), Cocoa Finder (vs. Carbon Finder), LLVM/clang/Swift (if you count Chris Lattner's work on it at UIUC)... Of those, the last one is very impressive: it's a decade-long from-scratch project that has succeeded in competing with a very entrenched project (GCC) in a mature market. Regarding GNOME 3, the delta between GNOME 2 and GNOME 3 is far less than the delta between NeXTSTEP+FreeBSD and the first version of Mac OS X. |
