How to install Linux operating system on Mac

Linux is an open source operating system that you can install on your computer for free. It offers several advantages over Windows and Mac, such as flexibility, privacy, better security, and ease of customization. If you have a Mac and want to explore a new open source operating system, check out the instructions on how to install Linux on a Mac below.

If you want to dual-boot Linux and macOS, you'll need to create a space for your Linux operating system to work in. To do this, you will have to partition your main hard drive. Here's how to do it:

Step 6. Set the partition size you need for your Linux operating system. You can do this by dragging the small white circles over the edge of the larger circle, or you can enter a size in the box next to Size. The gray part of the graph will be your Mac's capacity, while the blue part will be your new partition. You should spend at least 20GB for Linux. You can also add other information here, such as the partition name. Take note of the partition size, you will need this information later.

Step 7. Format the new partition as MS-DOS (FAT).
