Because Parallels for Mac uses hypervisor technology to map the host computer’s hardware resources directly to the virtual machine’s resources, the performance of Parallels for Mac virtual machines closely matches the performance of the host operating system. That could be an accounting software package such as TurboCASH, an easy-to-use email client like Mailbird, or, perhaps, Internet Explorer, which is still used by millions, so web developers have to optimize for it. Developed by Parallels Inc., a privately held software company with offices in 15 countries, Parallels Desktop for Mac (referred to simply as Parallels from here on) allows Mac users to seamlessly switch between macOS and the Windows operating system.The ability to do so is indispensable when your favorite software isn’t available for Mac. Parallels Desktop for Mac is a hardware virtualization solution for Mac computers with Intel processors.
