To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

If you don’t have Mojave supported Mac, you can download the Mojave Installer App using patcher tool. Open the macOS Mojave patcher tool. If it doesn’t open and says it is from an unidentified developer, right click on the tool’s icon and click on “Open” from sub-menu and then enter your Mac.

Why Can

Check compatibility

  1. Im aware I need to navigate to software update area of the system preferences app to update the macOS now but its November 2nd and my mac still says “Your Mac is Up To Date – macOS Mojave 10.14” Isn’t the 10.14.1 update out yet? Why can’t my mac sense there’s a software update already out?
  2. Hi, I found a solution for my issue. Hope it helps you. I made a reset to PRAM and SMC. Don't know why but after that, everything worked just fine. Never the less I can't say I'm happy with the mojave upgrade on my macbook pro mid 2012.

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.

If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Macbook softwares free download windows 10. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.

These installers from the App Store open automatically after you download them:

  • macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
  • macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
  • macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion

Your web browser downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

  • macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
  • OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
  • OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

Install macOS

Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Why Can

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

You might also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.

You'll need a very good reason and it'd be best if you didn't do it on your main Mac. However, installing Mojave on some older Macs can be done — and fairly easily. AppleInsider explains if you really must know.


This year's macOS Mojave beta, and subsequent update, won't run and can't be installed on any Mac older than about 2012 — or so Apple thinks. However, if you're the sort to believe that every year Apple tries to force everyone to buy new Macs, and you also forget that 2012 was six years ago, you're in luck.

But, there is now a way to ignore Apple and install macOS Mojave on any Mac you like. Or at least any Mac you like back to around 2008.

There are exceptions. The new and most utterly not Apple supported macOS Mojave Patcher Tool will even go back to 2007 if you have a very specific iMac that you've already upgraded in a very specific way. That said, Apple's official list also has exceptions: if you have the right Mac Pro you can install Mojave on even a mid-2010 machine.

We get that you may well not be able to afford a new Mac. These are far from cheap machines. Plus even a ten-year-old MacBook Pro is a good computer and we'd not be at all surprised if you were still getting great use out of it.

We would just then be surprised that you want to risk that great use by installing a macOS update that it can't handle.

The Mojave Patcher Tool for Unsupported Macs is available for download from DosDude1. This is the same guy that did this for High Sierra, and has supplied a series of other hacks and workarounds for fans of older Apple hardware.

Doubtlessly the tool is a clever piece of programming that is be far beyond our skill, but ultimately it just does one thing — it prevents Apple's macOS installation tool from spotting that the machine you're using is too old.

Other than that, it takes macOS Mojave and installs it on a drive. But, if you're now wondering where it gets Mojave from, you've spotted a potential hang-up in the process.

To get a copy of macOS Mojave to install on an unsupported Mac, you have to be in the Apple Beta program but more importantly than that, you have to download it on a supported Mac.

So, unless you've got friends who have newer Macs yet not enough conscience to warn you off this idea because it is potentially hazardous to your data and hardware, you've got to personally have a Mojave-capable Mac. If you have, go ahead, use Mojave on that.

Normally we'd be hesitant about that too. Apple's macOS, like any operating system, is so complex that it's bound to have some problems on older gear. Every year we generally advise you to wait a little while before installing the final version. Every year we also point out that installing the beta is fine so long as you do it on a spare Mac.

We say both of those things about Macs that are supposed to be able to run these things. Even when they are, the advice to wait for a while after official release is a good suggestion. The advice to stay away from the beta versions entirely on a critical work machine is more like a firm rule.


If you use this tool to install macOS Mojave on a Mac that Apple itself says won't work, you can't honestly expect a great experience. You're not going to transform that brilliant 2008 MacBook Air into a 2018 model. You're more likely to transform it into a somewhat less brilliant 2008 brick under more load than the hardware should have to bear.

It is good to have the same macOS on all of your machines, and it's even slightly disorientating when you're swapping between Mojave and Sierra. However, take the disorientation because it's better than having no functioning Mac at all.

One more thing. If you do use this patch tool to install macOS Mojave on your main Mac, please remember that you can still read AppleInsider on your iPhone if things go awry.
