Downgrading macOS might seem like a step backward, but when a new update falls short of expectations, it can be the smartest move.
Whether you upgraded to Golden Gate, Tahoe, Sequoia, or another version, the latest isn't always the greatest. The good news? You don’t need to be a tech expert to take back control. While there’s no magical “undo” button, there are several reliable ways to roll back your system.
Warning: Downgrading means erasing your startup disk, installing the earlier macOS, and then restoring your files. Anything you haven't backed up is lost. A backup made after you upgraded may not work with the older macOS, so use one from before the upgrade if you have it. Golden Gate runs only on Apple silicon Macs, so only those Macs can be downgraded from it.
Recovery reinstalls your current macOS in most cases, so it isn't necessarily a downgrade. If you installed a beta, you can also unenroll from the Apple Beta Software Program and install the next public release from Software Update.
Before downgrading macOS, protect your data and prepare carefully with this checklist:
Back up everything: Use Time Machine to back up your Mac to an external or network disk. For a clone, use Get Backup Pro. If you want extra safety, download Get Backup Pro to make a bootable clone.
Before downgrading macOS, you can also check your Mac serial number to run a quick lookup of your Mac serial to reveal important details.
Time Machine is the easiest way to back up your Mac. It backs up your files, apps, and user account, and you restore them with Migration Assistant after you install macOS. If you’d rather pick specific files or create a bootable clone, apps like Get Backup Pro or ChronoSync Express can help.
If you use Photos without iCloud turned on, export your latest albums and edits to an external drive before erasing your Mac. Also, write down any license codes, serial numbers, and custom app settings you’ll need later.
Finally, open Dropbox, Google Drive, or your preferred cloud service and wait until every file finishes syncing. Anything still uploading could be lost during the downgrade.
There’s no one-size-fits-all way to downgrade macOS. The right method will vary, depending on whether you have a backup, access to another Mac, or feel comfortable erasing your drive. Here are the three most reliable options: Time Machine backup, bootable installer, and macOS Recovery Mode.
Time Machine doesn't downgrade macOS by itself. Install the earlier macOS first (see the bootable installer steps below), then restore your files.
If you already have a bootable installer for the macOS release you want, simply plug it into your Mac, restart from it, erase your startup disk, and run the installer to roll back. If you don’t have one yet, follow the steps in this guide on how to create a bootable USB on a Mac. You'll need a 32 GB USB drive (16 GB is enough for most earlier versions) and access to the correct macOS installer file.
Download the installer from Apple. In Terminal, run softwareupdate --list-full-installers to see the versions available for your Mac, then run softwareupdate --fetch-full-installer --full-installer-version [number], replacing [number] with the version you want. Apple also provides App Store links for recent versions and web downloads for older ones. In most cases, you must download from a Mac that's compatible with that macOS.
Note: Your Mac must be connected to the internet during installation. If the macOS you install isn't compatible with your Mac, the installation might not complete.
Once you’ve made your bootable install disk, follow these steps:
Sometimes, a bootable installer is the best option when you don’t have a Time Machine backup or want a completely clean system. To reinstall macOS after creating your bootable drive, plug it into your Mac, restart while holding Option (Alt), and choose the installer from the menu.
Once macOS is reinstalled, you can restore your apps and files from your backup or start fresh. You can also explore other ways to install macOS after downgrading if you prefer working with older or archived versions.
Recovery isn't a guaranteed way to get an older macOS. What it installs depends on your Mac:
It's quite straightforward, and all you need is a stable internet connection and your Mac.
Here's how:
After downgrading macOS, your Mac is fresh and faster, but now it’s time to restore your apps, files, and settings. This is also a great chance to reorganize and optimize your system.
For a fresh start, reinstall apps manually from the Mac App Store or developers’ sites. It takes more time but helps eliminate old, bloated software. Your Mac will run smoothly with fewer background processes. Keep essential installers and license keys saved safely for easy access.
For files not in your Time Machine backup or stored in the cloud, copy them back thoughtfully. Create fresh folders and organize logically to avoid clutter. Restoring after a downgrade is your chance to reset and keep your Mac tidy from day one.
Downgrading macOS doesn’t have to be stressful. Whether you use Time Machine, a bootable installer, or recovery mode, you can safely roll back to a version that works best for you.
Just make sure to back up your data first and restore your apps and files afterward. With tools on Setapp like Get Backup Pro and ChronoSync Express, you can make the process smoother and keep your Mac organized every step of the way.

Yes, in most cases. You erase your Mac, install the older macOS, then restore your files from a backup you made before upgrading. You can install the older version with a bootable installer or, on an Intel Mac, use macOS Recovery to get the version your Mac came with. Apple only offers versions no earlier than the one that came with your Mac.
You can revert to the original OS on Mac using macOS recovery mode:
Download the installer from Apple. In Terminal, softwareupdate --list-full-installers shows the versions available for your Mac. Apple also provides App Store links for recent versions and web downloads for older ones. Only download from Apple.
To change your macOS version, start by backing up your data to avoid losing important files. Then, create a bootable installer by loading the macOS installer onto a USB drive. Plug in the bootable drive, restart your Mac from it, and follow the prompts to install the desired macOS version. Once the installation is complete, restore your apps and files manually or using a backup.
Any Mac can go back to a version it supports, but no earlier than the macOS it came with. Only Apple silicon Macs can run Golden Gate, so only they can downgrade from it. Intel Macs top out at macOS 26 Tahoe.
Back up your data using Time Machine or tools like Get Backup Pro before downgrading macOS. During installation, erase only your system volume, not external drives or backups.
Downgrading can cause app compatibility issues or driver errors if not done correctly. Always prepare backups with tools like Get Backup Pro and confirm installer authenticity to avoid problems.
Back up your Mac, then download the Tahoe installer from Apple and create a bootable installer. Erase your startup volume in macOS Recovery, start up from the installer, and install Tahoe. Then restore your files with Migration Assistant using a backup made before you upgraded to Golden Gate.
