It appears like they’ve aped some of MacOS design language, but it’s clear they’re engineers, not designers. There’s enough “uncanny valley” between this OS and actual modern Apple UI design that it comes off a bit like all those versions of KDE that tried to look and act exactly like Windows XP and always felt a bit “off.” Their screenshots page is a Frankenstein mess of poor font quality and Apple themes mixed toge…
