OS X Yosemite was released years ago; in fact, it is no longer supported. Nevertheless, it is still a great option for older Mac models — those no longer compatible with newer macOS versions. 

To install OS X Yosemite, the requirements are the same as they were for Apple’s OS X Mavericks. We’ll cover all the system requirements in this article, but let’s first start with disk space. Now, in terms of space, you’ll need at least 8 GB of free disk space. To check how much disk space you have, head to the section below.

How to check disk space for OS X Yosemite

How to check free disk space on your Mac

  1. Click the Apple icon at the top left of your screen.
  2. Select “About This Mac.”
  3. Underneath “Memory,” click on “More info…”
  4. In the new window, select “Storage.”
  5. Above the multi-colored bar, you will find the phrase “XX.XX GB free out of XX.XX GB.”

Again, if you have more than 8 GB of free space on your Mac, you can upgrade to OS X Yosemite. If you’re running a little low, check out this helpful guide — it’ll help you clean up gigabytes of disk space.
