What Is This Thing? --> Sorting through the confusion of this App Store version of Parallels Desktop, here are the details: (1) The actual OFFICIAL name for this version is: Parallels Desktop® App Store Edition. (2) The actual current version number really is 1.7.0, not 17.0. Beats me why! (3) Parallels WARNS: "NOTE: It is not recommended that existing Parallels Desktop for Mac users move to Parallels Desktop® App Store Edition. So IGNORE this thing unless you know you really want/need it. Get the full version instead, DIRECT from Parallels, NOT the App Store. Please. (4) So what is this thing good for? It's a 14-day DEMO only. All it allows you to do is create and edit virtual machine configurations. If you want to actually run a virtual machine, you have to SUBSCRIBE to Parallels Desktop for at least a year. (5) FYI: The cost for Parallels Desktop varies widely if you keep an eye on deals/sales on the net. If you're crafty, right place/right time, you can avoid paying full price. You're welcome.
