I witnessed this turnover first hand when I was hired on as a customer service representative at the launch of QuarkXPress 5. This was a major release given that they hadn't released a major version for 5 years! Hilariously enough, we were trained to tout OS X support... via Rosetta. Native support didn't come until QXP6.
While I do think the major reason why Quark failed was due to a lack of a native OSX app, I think there's another major reason... Creative Suite.
The vast majority of desktop publishing users required Photoshop and the pricing difference between Photoshop and Creative Suite was much less than adding (or even upgrading) QuarkXPress. There's also the integration between CS apps that Quark couldn't compete with.
On a sidenote, people have mentioned how Quark was sold to Fred Ebrahimi and he outsourced the vast majority of the engineering staff to India, but did you know he also created Quark City? http://www.quarkcity.com/
