Parallels Desktop 12.0.2
Parallels has released Parallels Desktop version 12.0.2 (build 41353) with several bug fixes for the virtualization software. The update rectifies a problem with printing from Windows using a shared Mac printer, fixes a bug that prevented using Control-click to open a contextual menu in virtual machines, and resolves an issue where the desktop would unexpectedly switch when in Full Screen mode while using an external monitor.
The Parallels Desktop 12 Standard Edition costs $79.99 as a one-time purchase or $79.99 per year as a subscription. Parallels Desktop Pro Edition costs $99.99 per year. For those who bought a non-subscription license, upgrades to the Standard Edition are $49.99, with a limited time offer to upgrade to a Parallels Desktop Pro subscription for $49.99-per-year for life. ($79.99 new for standard edition, $99.99 annual subscription for Pro/Business Edition, free update, 261 MB, release notes, 10.9.5+)
How about a comparison between Parallels and VirtualBox?
(I've used VB for years successfully with multiple versions of Windows and Office; lately the VMs have gotten terribly slow, but I gather that may be typical of Windows rather than a VB problem.
