Overview

Today, Apple announced their new macOS lineup i.e macOS Ventura 13.0 which is Apple's newest and most awaited OS. Monterey added massive updates and improvements from its predecessor, Big Sur.

Packed with new features and functionality, the most noticeable update that can be seen and experienced is the new GUI. Featuring a much more "iOS" look and feel and is as smooth as butter. With each release of macOS, Apple removes support for old hardware.

Unfortunately, with the announcement of macOS Ventura, Apple has officially dropped support up to Skylake. Luckily, for our users and readers, we're going to provide you with a complete installation guide step-by-step.

If you've made an attempt to install macOS Ventura before reading this guide, you've probably been greeted with the Internet Recovery or no-entry sign immediately after booting from the Ventura installer.

With this in mind, you'll have to use other ways to get macOS Ventura on your unsupported Mac.

Compatibility


Before you proceed with a clean installation, we suggest you to check the compatibility of the Mac model.


Have another Mac model and want to run macOS Ventura? You can find the complete list of supported Mac models for macOS Ventura and check whether your Mac model is listed. The compatibility list is linked below.

Requirements

Before you start with this guide, here are the requirements for setting up macOS Ventura on your unsupported Mac mini.

MacLate 2009, Mid 2010, Mid 2011, and Late 2012
Boot ROM VersionLatest Boot ROM installed
USB Flash DriveAt least 16GB

If you meet the above requirements, you're good to go and can start with the guide.

STEP 1: Create a Backup of your Mac
Before you proceed with the installation, we advise you to perform a backup of your Mac. In case the installation fails or you encounter any issue with the installation, you can roll back to your existing installation.

To create a Backup for your Mac, follow the guide linked below.

STEP 2: Download macOS Ventura
The next step is to download macOS Ventura. Normally, you won't be able to get new updates as you're using an unsupported Mac and Apple will block updates for the new OS. However, there's another workaround available and you can download a copy of macOS Ventura very easily. To download macOS Ventura, follow the guide below

STEP 3: Create macOS Ventura Bootable USB
After downloading macOS Ventura, the next step is to create the Bootable USB for macOS Ventura. To create macOS Ventura Bootable USB, follow the guide below.

STEP 4: Preparing the USB Installer
The next step is to prepare the USB installer for booting macOS Ventura. Typically, involving the preparation of EFI using OCLP.

1. On your target Mac, boot to Desktop.
2. Apple menu  > About This Mac>System Report
3. Note down the model identifier. In my case, it's Macmini7,1
4. Download OCLP from the download section of this forum.
5. Open OCLP and you'll see something similar to the screenshot attached below.

NOTE:
  • As you can see, I'm not having the option to Build and Install OpenCore as I'm running a Monterey capable Mac (Macmini7,1). It is strongly recommended that you use the target Mac to Build OpenCore as for a few Macs (Monterey Capable), the tool doesn't give the option.

6. OCLP detects the Mac model automatically. However, it is still recommended to select the target Mac model identifier from the drop-down selection, especially if you're running OCLP from any other than the target Mac. To select the target Mac model, simply click on con Settings and select the target Mac model identifier from the drop-down selection.

7. If you're using a Mac which is Monterey compatible (natively), select Allow native models checkbox.

8. Click on SMBIOS Settings and you'll see something similar to the screenshot attached below.
Screen Shot 2022-06-25 at 7.52.03 AM-min.png


9. Select Advanced in SMBIOS Spoof Level and then select the SMBIOS Spoof Model. As I'm using Macmini7,1, it would be best to select Macmini8,1 which is natively supported with macOS Ventura.

NOTES:
  • The Spoof Model should be natively supported with macOS Ventura.
  • Select the Spoof Model, depending on your Mac model. Do not select a different Platform, i.e For MacBookPro, select the ideal MacBookPro Spoof Model.

10. Click on Generate S/N and it will generate a Serial Number. The SMBIOS should be similar to the screenshot attached below.

11. Click on Return Settings and you should have something similar to the screenshot attached below.

When prompted, click on OK to allow disk access.

And within a few seconds, it will prompt to reboot.

19. Once, you're done with all the above processes, click on Reboot.

NOTE:
  • If you're preparing OCLP on any other Mac than your target Mac, do not restart your Mac. Instead, eject the USB and plug it into the target Mac.

STEP 5: Booting the macOS Installer
Once you finish setting up USB, you're ready to install macOS Ventura on your Unsupported Mac.

1. Start/Restart your Mac and while starting/restarting, hold down the option key. You'll see something like this below.

Now, macOS Ventura will begin installing to your selected disk.

NOTES:
  • Step #3 will format the target disk. Proceed with caution.
  • This will take a couple of minutes and will restart at "Less than a minute is remaining". Upon completion, the system will automatically restart. Your Mac will restart to complete the installation.

Here it ends the first phase of the installation.

When your Mac restarts, it will automatically boot from macOS Installer to continue the installation.

Once more, the Mac will restart and when your Mac restarts, it will automatically boot from macOS Installer to continue the second phase of the installation. Upon completion, your Mac will automatically restart.

After the second phase of the installation, your Mac will restart one more time, and this time it will automatically boot via Macintosh HD as shown below.

STEP 7: Finishing macOS Setup
After booting via Macintosh HD, the installation would be complete and it's time to set up the macOS for the first usage with the newly installed macOS.

When you're at the welcome screen, continue with the basics options such as Keyboard setup, Network, Computer Account, and Privacy settings.

Now the installation is complete!

NOTES:
  • During the installation process, your Mac might restart several times. You might get a blank screen at certain times but that's normal and the installer is still working in the background.
  • The first boot may be slower as the caches are not built yet. Once the caches are built, it will boot normally.

Enjoy macOS Ventura on your Unsupported Mac :)
