Apple’s new macOS Mojave doesn’t support the old Macs prior to 2012. It was a shocking news for me too.
You may also like to read the following posts:
I have an old, not for me actually, MacBook Pro which I purchased at the end of 2010. I was expecting Apple won’t drop the support of Mojave for MacBook Pro 2010 model, at least not for this time. But I was wrong. The latest Majove doesn’t support it too.
'Install MacOS Mojave.app': The last complete installation file is the only one that contains the createinstallmedia tool to create a start-up disc for Mojave MacOS. In case you're asking yourself what this patch is good for, the Mojave DosDude patch allows you to install Mojave MacOS on officially incompatible Mac hardware, however this is not. If you have hardware or software that isn't compatible with Mojave, you might be able to install an earlier macOS, such as High Sierra, Sierra, or El Capitan. MacOS Mojave won't install on top of a later version of macOS, but you can erase your disk first or install on another disk.
There is no need to worry. Even the oldest Windows 95 can be installed on Mac computer. There is a solution to every problem.
I don’t want to upgrade my MacBook Pro right now, especially when a new model is rumored to be released in next month.
Another choice for me was to buy a graphics card which supports Metal. In fact, it was the most feasible solution for to get installed Majove on my unsupported Mac right now.
Metal is natively supported by all Macs introduced since 2012. It means the following Nvidia, AMD and Intel family cards are compatible.
-Intel HD Graphics 400, Iris 5000 & 6000 family
-Nvidia GT 600M, 700M family
-AMD R9 M family
To check which GPU (graphics processing unit) is installed on your Mac computer, click on the Apple icon in the top left corner and then click on “About This Mac”.
There are a number of third-party vendors which sell graphics cards with integrated Metal support specifically designed for Mac computers. While searching for a compatible graphics card, I found that I could install Mojave on my MacBook Pro Mid 2010 model by using a software known as macOS Mojave Patcher Tool. Kudos to DosDude1 who developed tested, and released it as a free app.
By using this software, we could install the latest macOS version on early 2008 Macs.
Here is the step by step method to run Mojave on unsupported Macs.
The whole process can be divided into four parts.
- Part 1. Getting all the required things
- Part 2. Downloading the macOS Mojave Installer App
- Part 3. Making a bootable Mojave USB drive
- Part 4. Installing and Patching Mojave OS on the unsupported computer
We will discuss each part in details in the following paragraphs.
Part 1: Requirements to Run Mojave on Old Macs
Four things are required to get macOS Mojave installed on your forgotten-by-Apple Mac.
- Your Mac computer
It could be an early-2008 or newer Mac Pro, iMac, or MacBook Pro. The following models include under this category.
– MacPro3,1
– MacPro4,1
– iMac8,1
– iMac9,1
– iMac10,x
– iMac11,x
– iMac12,x
– MacBookPro4,1
– MacBookPro5,x
– MacBookPro6,x
– MacBookPro7,1
– MacBookPro8,x
It could be late-2008 or newer MacBook Air or Aluminum Unibody MacBook. The following models include under this category:
– MacBookAir2,1
– MacBookAir3,x
– MacBookAir4,x
– MacBook5,1
It could be early-2009 or newer Mac Mini or white MacBook including the following models:
– Macmini3,1
– Macmini4,1
– Macmini5,x

– MacBook6,1
– MacBook7,1
And it could be Xserve2, 1 and Xserver3, 1.
- A USB drive in 16GB size or above
- macOS Mojave patcher tool. Download it here.
- A copy of the Mojave software.
Part 2: Download macOS Mojave Installer Software
MacOS Mojave software can be downloaded as an Installer App from Mac App Store using the computer which supports Mojave.
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’s Admin name and password. After the verification, you can open it with the left double-click.
If you don’t remember your macOS password, here are the solutions to reset it.
Go to Tools in the Menu bar and then hit “Download macOS Mojave”.
I recommend using the built-in downloader tool because it will download the latest and the compatible Installer app.
Mojave Installer app is about 5-6GB in size and it may take some time depending on the speed of your internet.
If the internet connection interrupts while downloading the file, don’t worry. The downloading process will resume where it left. Simply download the Mojave software again but point it to the same location where you were already downloading and saving the installer app.
Part 3: Create a Bootable Mojave USB Drive
In order to create a bootable Mojave USB Installer drive, follow these steps.
Step 1: Insert 16GB or above USB drive into your USB port of your Mac.
Step 2: Open Disk Utility and erase the USB drive in OS X Extended (Journaled) format. Give a proper name before erasing. I gave the name “macOS Mojave” to my USB drive.
If you are new to Mac, get the basic information about how to make a Partition, erase the current partition and how to make a bootable USB drive.
Step 3: After the drive is erased, open “macOS Mojave Patcher” tool.
Step 4: Point the Patcher tool to the downloaded Mojave Installer app which is downloaded in Part 2.
Step 5: Now select the target USB drive you just formatted.
Step 6: Hit the “Start Operation” button on the patcher tool and let it make the USB bootable with Mojave.

Step 7: It will show “Complete” when the process is done.
Part 4: Installing and Patching macOS Mojave
In this fourth and final part, we will install and patch the macOS Mojave on our old Mac computer. Follow the steps below to complete the remaining procedure.
Step 1. Restart your computer and hold down the “Option” key as soon as the Mac starts up.
Step 2: Select the USB drive, which was named as “macOS Mojave” as the startup disk.

Step 3: If you want to upgrade your current macOS to macOS Mojave, simply use the continue button to proceed and follow step 5. But if you want to install it on another partition or want to erase the current partition first, then follow the Step 4.
Step 4: Open Disk Utility from the bottom left panel.
Select the volume you want to erase. Use Mac OS Extended (Journaled) format. Or if you have got late-2009 and later machines with SSD drives, you can also use APFS format.
If you don’t want to install Mojave on current volume, you can also create a new partition and install it there. Mojave takes approximately 18GB space on hard drive. So at least make a 25GB partition to test the new macOS.
If you want to use it for all routine work, set the partition size according to your needs.

Step 5: Select the volume and press “Continue” to begin the installation process.
Step 6: The installation process takes about 20 minutes to complete. When it is done, reboot your Mac back into installer drive while holding down the “Option” key again.
Step 7: This time select “macOS Post Install” app from the bottom left panel.
Step 8: Select the model of your computer and the volume on which you installed Mojave and then click the “Patch” button. The tool will automatically select the required patches according to the model of your computer.
Step 9: Press the “Reboot” button when the patch is complete.
Step 10: The computer will reboot with macOS Mojave installed on it.
Step 11. If it doesn’t work properly on the restart, boot your Mac back into the installer USB drive, select macOS Post Install again, and this time also select “Force Cache Rebuild” option. Once the patch is complete and the cache is rebuilt, reboot.
Step 12: Upon restart, complete the setup process and start using your Mac with a Mojave operating system.
Happy Mojaving!!

Note: You will see a new “Patch Updater” app in the Applications under “Other” folder. It will alert you when new patches are available for your computer.
Your Mac will get the future Mojave updates as other supported computer do. If you don’t see the updates, or your computer doesn’t work properly after applying the update, use the step 11 of Part 4 to enable all patches.
Downgrade Catalina to Mojave
If you’ve installed macOS Catalina and run into problems with some of your apps, or you’ve just decided that you don’t like it as much as Mojave, the good news is that you can downgrade back to the previous version of macOS. The bad news is that it’s a lengthy process with several steps. Read on to find out how to do it.
1. Back up your Mac
You should have backed up your Mac before you upgraded to Catalina, as you should before you perform any major upgrade or make any significant change to your Mac. However, the files you’ve been working on since you upgraded won’t be up to date on that backup. So, you should copy those files to an external disk, or a cloud storage service like Dropbox or iCloud Drive so you can retrieve them easily when you downgrade. We’re going to completely erase your Mac’s startup disk, so it’s important to copy anything you need now.
Before you backup, however, you should take steps to remove the junk and clutter from your Mac. There’s no point in backing up all the clutter along with the files you really need. To do that, I recommend CleanMyMac X. It’s the easiest way to clear out the clutter on your Mac. Here are just a few things it can do:
- Delete years worth of system junk
- Find hidden apps and folders
- Neutralize Mac-specific malware, like key loggers
- Manage hung apps and heavy CPU consumers
- Update all your software to the latest-supported versions
As you can see, CleanMyMac X does a lot more than just clear out junk files before you backup your Mac. It’s well-worth keeping it on your Mac and using regularly to keep your Mac running smoothly.
2. Save your passwords

When you downgrade mac OS Catalina, you’ll delete everything from your hard drive, including licence keys and settings. So, in addition to making sure you copy all the files that have changed since you last backed up, you should make a note of those. If you use a password manager that syncs with other devices and allows you to store licence codes and encrypted notes, you could use that. If not, any app that allows you to sync encrypted notes will do. Or you can use Apple’s Notes app. It’s also a good idea to take screen grabs of settings to make it easier to restore them later. Remember to copy the grabs to a cloud storage service or an external disk.
3. Create a bootable installer of macOS Mojave
Note, you can skip this step if your Mac shipped with macOS Mojave or if you made a backup with Time Machine before you upgraded to Catalina.
- If you’re reading this before macOS Catalina ships, you can go to the App Store and search for Mojave, then download it. If it tries to install when it’s finished downloading, quite the installer.
- If you’re reading this after Catalina ships, you can download Mojave here, but only on a Mac that’s not already running Mojave. When you click that link, Software Update will launch and start to download Mojave. When it’s finished, quit Software Update.
- Grab a USB stick with 16GB capacity or an external hard drive or SSD and plug it in to your Mac.
- Launch Disk Utilities and Erase the Drive or USB stick, formatting it as Mac OS Extended (Journaled) and selecting GUID partition map if a selection is available.
- The easiest way to create a bootable installer is to use DiskMaker X. However, you can also do it in Terminal like this:
- Launch Terminal from Applications - Utilities
- Type:
sudo /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitledwhere ‘Untitled’ is the name of your USB stick or external hard drive - Press Return and wait for the word Done to appear in Terminal.
Whichever method you used, you should now have a bootable macOS Mojave installer. Keep it safe.
4. Uninstall macOS Catalina
- Make sure your Mac is connected to the internet.
- Click on the Apple menu and choose Restart.
- Hold down Command+R to boot into Recovery mode.
- Choose Disk Utility in the macOS Utilities window
- Select your startup disk
- Choose Erase
- Quit Disk Utility

How to downgrade Catalina to Mojave if your Mac shipped with Mojave
- Once you’ve erased your startup disk and quit Disk Utility as described above, choose Reinstall macOS from macOS Utilities.
- Press Continue.
How to rollback from Catalina using a Time Machine backup
If you backed up your Mac with Time Machine before you installed Catalina, you don’t need to create a bootable installer – you can just reinstall Mojave from your Time Machine backup. Make sure it’s plugged in if it’s an external disk. If it’s a network disk, make sure you’re connected to the network.
- Once you’ve erased your start up disk as described above, choose Restore from Time Machine backup in the macOS Utilities window.
- If your backup is on an external disk, select it. If it’s on a network disk, select it and choose Connect to Remote Disk.
- Type in your username and password for the remote disk if necessary.
- Select the data and time of the backup you want to restore from.
- Follow the onscreen instructions.
5. Install Mojave using a bootable installer
If you have a Mac that didn’t ship with Mojave and you don’t use Time Machine to backup, you’ll need to reinstall Mojave from the bootable installer we created earlier.
- Plug in the installer disk.
- Go to the Apple menu and choose restart, then hold down the Option key.
- Mojave will start installing on your Mac.
- When it’s finished, your Mac will restart and the Setup Assistant will appear
- Follow the steps in the SetUp Assistant to set up Mojave

If you have reinstalled Mojave from a bootable disk, rather than a Time Machine backup, you will need to reinstall applications and copy documents across from your backup. That’s where those notes and screen shots you made earlier come in handy!
Once you’ve restored your settings and reinstalled all the apps you need, your Mac is ready to use again, running Mojave instead of Catalina.
Tip: If you want to roll back to an earlier version of macOS than Mojave, you can. To reinstall the OS your Mac shipped with, use the method in ‘How to downgrade if your Mac shipped with Mojave’. If you want to roll back to a version of macOS newer than the one your Mac shipped with but older than Mojave, you can download Sierra and earlier versions from the Mac App Store. Then follow from Step 3 in ‘Create a bootable installer of Mojave’.

My Mac is still underperforming, what to do?
You thought that reverting to macOS Mojave would get your Mac back to norm. But if it didn’t and you still experiencing sudden freeze-ups and glitches, full disk cleanup is your answer. Probably there are too many conflicting system junk files on your drive that you need to plow through.
You don’t need a regular disk cleanup app — most of them are scam — but this tool, CleanMyMac X, is notarized by Apple, and can really do helpful optimizations on your Mac.
- Download the free edition here
- Go to Maintenance tab
Now you can perform some of the tasks suggested by the app, like running Maintenance Scripts. Also, check the System Junk tab and remove all the useless files it recommends you to delete.

As you can see, it is possible to uninstall Catalina if you decide you don’t want to continue using it. It’s essential, however, that you backup your Mac before you upgrade. And remember, before you backup, clear out the clutter with CleanMyMac X. That way you won’t use precious space on your backup drive copying over junk files.
