Is your Mac compatible with macOS Mojave?

Where iOS 12 will run smoothly on any device that supports iOS 11, the same can’t be said of the new macOS — not all High Sierra systems have the specs to run Mojave. That said, unless you’re using a really old Mac, there’s every chance you’ll be able to install and run macOS 10.14 without a hitch.

MacOS Mojave compatibility

Apple says that macOS Mojave will be available for all Macs introduced in “mid-2012 or later, along with 2010 and 2012 Mac Pro models with recommended Metal-capable graphics cards.”

What does this in terms of specific models? Well, if your system is any one of the following machines, you’re in luck.

  • iMac Pro (2017)
  • iMac (late 2012 or newer)
  • Mac Pro (late 2013, plus mid-2010 and mid-2012 models with Metal-capable graphics cards)
  • MacBook (2015 or newer)
  • MacBook Air (mid-2012 or newer)
  • MacBook Pro (mid-2012 or newer)
  • Mac mini (late 2012 or newer)

If you’re unsure what Mac model you own, here’s how to find out.

  1. Click on the Apple logo in the menu bar and select About This Mac.
  2. In the Overview tab, you’ll see the Mac model and year.

About this Mac

The macOS Mojave requirements mean that it won’t be as widely available as High Sierra. The current macOS is compatible with iMacs and MacBooks from 2009 onwards. For those older machines, High Sierra is where the road ends, unfortunately.

When is macOS Mojave available?

If your Mac meets the Mojave system requirements you can get your hands on the new OS right now. However, there is a caveat: the current version is a developer preview for Apple Development Program members only.

A public beta version is available from the end of June, with the full and final version released in fall. If previous macOS releases are anything to go by you can probably expect it to arrive in the Mac App Store in September or October.

How much disk space will I need for macOS Mojave?

MacOS Mojave will require around 4.8GB of free space, although, the more space you have the better, especially if you plan on installing new apps from the overhauled Mac App Store.

You can check how much free space you have available in About This Mac.

  1. Click on the Apple logo and select About This Mac.
  2. In the About This Mac window, click on More Info, then choose the Storage tab.

If your hard drive looks like it needs some space freeing up, you can search through your system files and drag any you no longer need to the Trash. However, this is a time-consuming task. A much better way to quickly remove junk files is with CleanMyMac 3.

CleanMyMac 3 is a utility tool that’s capable of scanning your system and automatically detected old, broken, and outdated files for deletion. It turns a laborious task into one that takes a matter of minutes, with only a few clicks of the mouse required on your part.


  1. Download and launch CleanMyMac 3 (It’s free to download).
  2. Select Smart Cleanup.
  3. Click Scan and wait for the app to do its thing.
  4. Click Clean and all of those pointless files will disappear for good, leaving behind a surprising number of gigabytes of free space.

Yes, it really is that easy.

How to install macOS Mojave

Installing anything on Mac is a breeze and that doesn’t change just because a shiny new OS has waltzed into town.

If you’re an Apple Development Program member you can download the Mojave Development Preview from developer.apple.com.

If you want to give the beta version a go it can be downloaded from beta.apple.com.

The full version will be available as a free upgrade in your Updates and the Mac App Store later in the year.

When your chosen version has downloaded, all you need to do is accept Apple’s terms and conditions, select the disk you want to install Mojave on and let your Mac take care of the rest.

Apple’s new operating system looks promising. Actually, it looks fantastic. If your Mac meets the Mojave system requirements, use CleanMyMac 3 to ready your computer and make Mojave at home. We’d recommend waiting for the full release in fall before you go ahead and download it, but if you’re happy with a few bugs and errors, or you’re a developer, go ahead and take an early version for a test drive.

CleanMyMac is designed to rid your system of junk files to free up disk space and improve performance. Download it today to get your Mac ready for macOS Mojave.
