How to install macOS Sonoma

Announced in June macOS Sonoma will only come out in the fall. But if you can't wait to try out the interactive desktop widgets, game mode, and other features right now, you can install the beta version of the OS.

1. Check Compatibility

Apple is always trying to provide the widest possible support for devices, and macOS Sonoma is no exception. The new OS will run on all relatively modern Mac. However, just in case, check if your gadget is on the list:

• iMac 2019 and newer;
• iMac Pro 2017;
• MacBook Air 2018 and newer;
• MacBook Pro 2018 and newer;
• Mac Pro 2019 and newer;
• Mac Studio 2022;
• Mac Mini 2018 and newer.

2. Make a backup

The new macOS is still at an early stage of development and contains errors that will most likely appear during operation. Therefore, in order not to lose important data, be sure to back up your system in Time Machine.

For this:

• Connect a disk for backups.
• Go to Settings → General → Time Machine.
• Select the drive, right-click and click Back Up to Time Machine Now.
• Wait for the copy process to complete.

3. Join the Beta Program

To download software that is in beta testing, you must become a member of the Apple Developer Program. It will be enough to log in with your account Apple ID - You don't have to buy a membership.

Proceed like this:

• Download the Apple Developer app from the link above and run it.
• Click "Account" and sign in with the current account you already use on your Mac, or another.

4. Turn on Beta Updates

By default, the OS is not updated to beta versions, so you need to force this feature to be enabled in the settings so that the system "sees" macOS Sonoma.

• Go to "Settings" → "General" → "Software Update".
• Click the i icon in the Beta Updates row and select macOS Sonoma Developer Beta.

5. Install macOS Sonoma

Now all that remains is to install an update that will update the system to macOS Sonoma. Keep in mind that you will need at least 14 GB of free disk space.

• Under General → Software Update, wait while your Mac checks for updates. You may need to close Settings or restart your computer.
• When macOS Sonoma is detected, click Update Now, agree to the terms of use, and enter your password.
• Wait for the download to finish. After that, the Mac will reboot and the standard installation will begin.
