On an Apple Silicon Mac, downgrading to an older macOS version requires a full erase of your computer's internal drive.
You cannot simply install an older version over a newer one.
Before you begin, you must first create a complete backup of all your data.
Step 1: Back up your Mac
This is the most critical step. Downgrading will erase your Mac's internal drive, so you must back up your files and settings beforehand.
Time Machine (recommended): Use Apple's built-in Time Machine to create a full backup on an external storage drive.
Manual copy: Alternatively, you can manually copy all your essential files to an external hard drive.
Step 2: Create a bootable installer for macOS 15
To install the older operating system, you will need a bootable USB installer.
Download the installer for macOS 26.xx, download the "Install macOS Tahoe "
In the Terminal application use this command to download Tahoe 26.3
softwareupdate --fetch-full-installer --full-installer-version 26.3
Use Terminal: Connect a USB flash drive with at least 15GB of free space. Open the Terminal app (in Applications/Utilities) and use the createinstallmedia command to turn the USB drive into a bootable installer. The command for macOS 26 Tahoe
sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
(Replace MyVolume with the name of your USB drive)
Step 3: Erase your Mac's internal drive
Shut down your Mac: Turn off your computer completely
Enter Recovery Mode: Press and hold the power button until you see the "Loading startup options" screen.
Choose Options: Click the Options icon, then click Continue.
Open Disk Utility: From the Recovery screen, select Disk Utility and click Continue.
Erase the drive: In the sidebar, select your Mac's internal drive, usually named "Macintosh HD." Click the Erase button and enter a new name for the volume. Ensure the format is set to APFS, then click Erase Volume Group.
Step 4: Install macOS 26 from the bootable installer
Quit Disk Utility: After the erase is complete, close Disk Utility to return to the Recovery menu.
Select the installer: Click the Install macOS Tahoe option. You may need to connect to Wi-Fi at this point.
Choose the drive: Follow the on-screen instructions and select the internal drive you just erased as the destination for the installation.
Complete the installation: Wait for the installation to finish. Your Mac will restart several times.
Step 5: Restore your data
Restore manually: If you copied your files manually, you can skip Migration Assistant and drag your backed-up files back into their respective folders.
