If you’re switching from a PC you can even use the supplied Windows tool to dump the OS and applications to a virtual disk file with a few clicks, and painlessly migrate it into Parallels: we tried a fairly clean Windows 7 installation occupying 30GB on disk, and found it took about an hour.Follow these steps in macOS Catalina or later:
We were pleased to see that Parallels was able to load Windows from our existing Boot Camp partition, although you can also install to a virtual disk file. Running Windows 7 natively in Boot Camp, this hardware achieved an overall score of 0.93 in our benchmarks. To put this to the test, we tried it out using mid-range hardware: a 20in iMac with 2GB of RAM and a Core 2 Duo T7300 processor. Performance is always an issue with virtualisation, thanks to the overheads of running two operating systems at once, but Parallels claims to give the smoothest Windows-on-OS X experience available. The real selling point for version 6, though, is speed. OS X parental controls are automatically applied to Windows applications, and keyboard shortcuts can be synchronised between operating systems to reduce confusion as you switch between platforms. There are a few other additions too, including Spotlight support for Windows files and 5.1 surround sound for anyone watching movies or playing games on a virtual PC (although be warned that there’s only support for DirectX 9).
