Schmitz Offering support for Apple's upcoming OS X Yosemite, [1]Parallels Desktop has been updated to version 10 with promises of speed enhancements up to 48 percent, up to 10 percent less memory used by virtual machines, and up to 30 percent extended battery life. Parallels Desktop 10 enables you to take advantage of many of Yosemite's announced features, including iCloud Drive, iMessages, and SMS text sharing. You'll also be able to share files, text, or Web pages from Windows using Internet accounts configured on your Mac. The virtualization software also improves on how it stores files on your Mac, with real-time optimization automatically compacting the virtual disk and a Disk Space Wizard that enables you to manually review and clean up space used by Parallels Desktop and your virtual machines. Additionally, Parallels Desktop for Mac Enterprise Edition has been updated to version 10 with support for enforcing USB device policies and encrypting virtual machines using FileVault. If you have a license for either Parallels Desktop 8 or 9, you can upgrade to version 10 now for $49.99. If you're new to Parallels, you'll have to wait until 26 August 2014 to purchase the full retail version of Parallels Desktop 10 for $79.99 (which is when we suspect a free trial will also be made available). If you purchased and activated a license for Parallels Desktop 9 on or after 1 August 2014, you're [2]eligible for a free upgrade.
