can anyone direct me where to download PD PVM file, which can be used in Parallels desktop directly?
I try to covert the Yosemite dmg file to PD, but failed.
It doesnt exist - you are going to need to make it yourself since Apple wouldnt allow you to distribute OSX without a valid license - unenforceable unless it came from Apple itself and they arent going to distribute it no matter what.
You want to VM OSX? Its allowed via the license, but you have to do it yourself.
