I agree. I'd like to see some themes that are Mac-inspired but are not clones, which seem to suffer from this "uncanny valley" you mentioned. To add, Mac OS is much more than its visual elements; the Macintosh Human Interface Guidelines establishes what it means for a Mac application to be one by specifying rules that not only apply to visuals, but also to behaviors. Historically Mac users rejected software that did not comply with the Macintosh Human Interface Guidelines (for example, the widespread rejection of Microsoft Word 6 for Mac, which was decried as too Windows-like, which caused people to stick to the well-received Word 5.1). It's possible to make an application built using Win32, GTK, or Qt to look like a Mac application simply by applying themes with a high degree of fidelity to the Mac. However, themes are unable to change the behavior of the applications to bring them in line with the Macintosh Human Interface Guidelines. A typical GNOME application with a Mac theme is still a GNOME application. Of course, in an era where cross-platform apps are increasingly becoming the norm, there's less concern about adhering to a platform's UI/UX guidelines. I still believe there is value with having an ecosystem of applications that largely comply with well-thought UI/UX guidelines, which is one area where the Mac has absolutely shined throughout its history.
