Correct (I am sure I didn't have to enter any credentials on the old Mac, or if I did, it gave me access to the whole host).
My setup is NOT 10.6.8 - that is the VM I am running (precisely because it's obsolete it manages to run old software, e.g. Journler, that I rely on; that's the whole reason I bought Parallels in the first place.). My host setup is not 10.6.8, it's 10.9.5, which is itself only "obsolete" because of Apple's ridiculous habit of releasing a new Mac OS every year. 10.9.5 is in fact barely older than the current Windows 10 version.
As for Parallels needing an update, that is not the issue as you should know if you've followed this topic properly - the EXACT same version of Parallels running in the EXACT same version of OS X on my previous iMac of EXACTLY the same age, did not cause the issue I'm reporting here. THAT is the problem you need to resolve, rather than diverting my attention with irrelevancies about updates that don't relate to the problem itself.
