- Apple is preparing for macOS 10.13 High Sierra, the newest version of its Mac operating system, which is supported on the Mac mini, iMac, Mac Pro, MacBook, MacBook Air, and MacBook Pro. There are a few big features coming our way and lots of under-the-hood fixes as well.
- I have around 100GB of space on my (27-inch, Mid 2017) iMac's SSD. I'm planning on using Bootcamp to play some Windows games, and I'm not sure how much space I need to leave for each OS. I'll be storing all the Windows programs and apps on an external hard drive, so I'm not sure how much I need to leave to Windows 10 itself.
- As you are eager to upgrade to macOS 10.13 High Sierra that will be available for download on September, you should first check the RAM of your computer. Looking at Mac OS X 10.11, it works on Mac 2009 and above that have 2GB RAM. Therefore, to upgrade to macOS 10.13, you should not be running less that 2GB RAM.
Mac mini (2014 and later) iMac (2014 and later) iMac Pro all models (2017 and later) Mac Pro (2013 and later) If you'd like more on compatibility, including other requirements, take a look at Christian's helpful article on whether or not your Mac can handle macOS Big Sur 10.16. How much storage space do you need to run macOS Big Sur? In order to run High Sierra on Mac, you will need at least 8 GB of available disk space. Once you do the upgrade to macOS High Sierra, you'll get more free disk space because of the new Apple File System and HEVC which is a new encoding standard for videos.

Apple uses its App Store to distribute its software, like new Macoperating systems. It's convenient, but sometimes it can take a while fora download to finish. And if you have multiple Macs, it's inefficient todownload the new OS to each and every Mac.

That's why I like to make a bootable external drive for the sole purposeof installing the Mac operating system. When I need to tend to a bunch ofMacs, it's much faster to use a bootable drive instead of going to eachMac, launching the App Store, searching for the operating system,downloading it (after entering my Apple ID), and then running theinstaller.
You can create a bootable USB flash drive with the macOS Sierra installerthat's now available. The installer software will take up nearly 5GB ofstorage space. Here's how to create a bootable macOS Sierra installerdrive.
Download the macOS Sierra installer

Don't worry if the drive isn't formatted for the Mac. The drive will bereformatted automatically as part of the process. Change the name of yourdrive to Untitled; you need to do this for the steps below.
