Thank you for the links -- the KB article "What versions of PD are compatible with OS X 10.10" dates from several months ago with an "update" in September and refers only to the "public beta" (does not mention which one). Therefore the KB article is not relevant. Is there an official statement about the compatibility PD 9.24251 and OS X 10.10 as they exist today October 18, 2014?
The KB article "Parallels Desktop 10 OS X Yosemite specific features" does not address what features of OS X 10.10 would be lost by using PD 9. The article merely mentions features of OS X 10.10 that are not available to anyone unless they upgrade OS X 10.x to 10.10. The article does not answer the question posed by the warning box that opens when PD 9 is launched on 10.9.5 that PD 9 is not compatible with 10.10.
Since the KB articles are not answers, I'll ask again: (1) what is the official word from the Parallels company on PD 9 compatibility with OS X 10.10 (final) -- does the company know for a fact that every feature in PD 9 will fail, or every feature succeed, of something in between? (2) what PD features are lost in Yosemite (final) if we use PD 9 instead of PD 10?
