If you are one of those who have seen the latest announcement of macOS Sequoia and discovered it's not compatible with your Mac, you don't need to worry. We will share the right ways to help you install macOS Sequoia on Unsupported Mac.

Begin by downloading macOS Sequoia Resource, creating a bootable macOS Sequoia USB, installing the OpenCore Legacy Patcher, and then finally installing macOS Sequoia on an unsupported Mac. While it might seem like a couple of quick fixes, you'll need to thoroughly read the guide to avoid any installation problems. Let's get into it!

Step 1. Download macOS Sequoia Resource

To start the process of installing macOS Sequoia on your unsupported Mac, the first critical step involves downloading the macOS Sequoia installer. Below are the detailed steps on how to obtain the installer directly from Apple using a trusted resource:

Step 1. Open your web browser and go to macOS Sequoia Full Installer Database.

Note: This database will provide download links for the macOS Sequoia complete Installer pkg files (InstallAssistant.pkg). This is the identical complete installation that you would get from the App Store for Intel and Apple Silicon M1/M2/M3 Mac computers.

Step 2. Look for the macOS Sequoia BETA Full Installer section and download the suitable one. The InstallAssistant.pkg is kept on Apple's servers and includes the whole "Install macOS.app" file.

Step 3. Once downloaded, install the pkg to find the entire macOS installer in your programs folder. You can also download and install macOS Sonoma on unsupported Macs with this website.

Step 2. Create Bootable macOS Sequoia USB

Installing macOS Sequoia on an unsupported Mac requires you to create a bootable USB on a Mac. If the USB you are using is not empty, remember to back up essential data in advance and protect your data before installing macOS Sequoia! The installation process might fail, particularly on unsupported Mac systems, causing data loss. We suggest EaseUS Data Recovery Wizard for Mac. This utility is great for backing up data and retrieving files lost during installation.

While protecting your sensitive information, the EaseUS Data Recovery Wizard for Mac gives you peace of mind. The outstanding tool can recover deleted files on macOS Sequoia and support multiple file formats such as images, videos, and documents more efficiently in no time. Recover data from USB drives, hard drives, partitions, and more.

Here are the steps to create a bootable USB:

Step 1. Connect a 16GB USB flash drive to your Mac. Use an empty USB or back up crucial data beforehand, as creating a bootable USB flash drive will wipe all data.

Step 2. Search Spotlight or go to "Applications > Utilities > Disk Utility". Or wake up with Spotlight.

Step 3. In "Disk Utility", choose your USB drive from the sidebar. Click "Erase", choose "Mac OS Extended (Journaled)", and name it "Sequoia". Click "Erase" to continue.

Step 4. After formatting the USB device, open "Terminal" and run the following command, substituting '/Applications/Install macOS Sequoia.app' with your downloaded installation location:

sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

Step 3. Install OpenCore Legacy Patcher

Follow the steps below to complete this section:

Step 1. To obtain the most recent version, go to the OpenCore Legacy page on GitHub and select the "Getting Started" button. Open OpenCore-Patcher (GUI) and choose "Build and Install OpenCore". Follow the on-screen instructions to create the Mac OpenCore package.

Step 2. Once OpenCore Legacy has completed creating the OpenCore package for your Mac, go to the Install OpenCore step.

Step 3. Follow the on-screen instructions to install the package on the USB stick you formatted in the previous section. This creates a bootable USB installer from the Sequoia installer you downloaded.

Step 4. When OpenCore Legacy has completed creating the installer, remove the USB stick from the Mac and insert it into the Mac where you want to install Sequoia.

Step 4. Install macOS 15 on Unsupported Mac

After creating a bootable macOS Sequoia USB and installing OpenCore Legacy Patcher, you may install it on your unsupported Mac. This brief guide shows how to continue:

Step 1. Plug the bootable macOS Sequoia USB drive into the unsupported Mac you want to upgrade.

Step 2. Power on or restart your Mac, holding down the "Option" key immediately until the boot selection screen appears. Select the "USB drive" containing macOS Sequoia and press Enter.

Step 3. From the macOS Utilities window, choose "Install macOS." Select your Mac's internal drive and start installation using the on-screen instructions. This may take time, so be patient.
