The list of new features in v15 isn't, perhaps, as long or impressive as it has been in recent years, but there are some important architectural changes to the software that are designed to keep Parallels Desktop aligned with changes to macOS itself, and which will particularly appeal to business and professional users who are keen to get the best performance from the Windows apps that they need to run on their Macs. This year is no exception, with Parallels Desktop 15 arriving on schedule, just ahead of Catalina itself. The arrival of the new macOS - version 10.15 this year, codenamed 'Catalina' - is generally accompanied by a new version of Parallels Desktop, one of the leading virtualization tools that allows Macs to run Windows applications and software alongside native Mac apps. It's part of the annual Apple lifecycle that the approaching Fall brings new iPhones and new versions of both iOS and macOS.
