@jemima and @ptzanni, you might want to look into installing bootcamp on your Mac. This is a process where you devote a part of your Mac hard drive to installing Windows and then when you start your laptop, you can choose whether to go into Mac OS or Windows. They run completely separately, so it should run better than Parallels. The big difference is that you don’t have access to any of your Mac folders etc when you are in Windows, they run as two separate installations. It doesn’t cost anything to do this, but you will need a copy of Windows 10 to install.
