If you've always wished you had a Mac but had to settle for a Windows PC, this is a nice way to play pretend. Three buttons on the top-right corner of your windows will be replaced with the classical OS X stop lights, the start menu will be moved to the top of the screen just like Apple's dock, and even the regular desktop wallpaper will be changed to the Yosemite's default one. This visual enhancement completely changes the way Windows 10 looks, making it resemble Apple's popular operating system. Let's start things out with a classic: the OS X Yosemite Theme. Before we begin, my advice is that you backup your system before installing any of the themes or applications presented in this article so that, in case something goes wrong, you will have a safety net to fall onto.
