How to Make My Windows Computer Look Like a Mac Desktop
- 1). Download the Mac theme from ThemeDoctor.com (see Resources) and save it in a spot you'll remember later. The theme will be in a .zip file format.
- 2). Find the theme file you downloaded and unzip it to "C:Windows/Resources/Themes" using your preferred extraction program.
- 3). Apply the theme. Right-click on an empty space in your desktop, choose the "Properties" option and go to the "Themes" tab. Click your new theme, then click on "Apply."
