How to Install Windows 10 on Mac Without Bootcamp

There are many options when it comes to installing and running Windows 10 on a Mac computer. One of the most popular options is to use Mac OS built-in Boot Camp Assistant software.

But unlike the other apps that come with Mac OS, Boot Camp has a couple of drawbacks regarding its performance and functionality. Such as,

  • It currently supports only a single partition drive.
  • Often gives unknown error messages with minimal information.
  • Every time it launches, it will automatically download 1.6 GB of Windows drivers. And it is placed under “/Library/Application Support/BootCamp/WindowsSupport.dmg”.

So in this article, we will teach you how to install Windows 10 on Mac OS without using a Boot Camp.
