Labels in the tabs are drawn using a drop shadow which looks nice for Aqua; however, in DarkAqua the shadow makes the text look blurry as it is a white color blended with the background. For macOS 10.14 Mojave in DarkAqua the drop shadow is no longer shown.
NSCell was deprecated in macOS 10.10 Yosemite. For reason I do not fully understand MMTabBarView draws the tab view in both the view code and the cell code; however, in Mojave this can cause problems. As the NSCell drawing implementation is redundant it is disabled in macOS 10.14 Mojave to prevent anomalous drawing with the wrong appearance.
