Before you do, you must make a Time Machine backup of your data and save it to an external hard drive.<\/p>\n\n\n\n<p>You will need:<\/p>\n\n\n\n<ul><li>Your Mac<\/li><li>Usernames and passwords, written down<ul><li>The administrator username and password you use to log in to your Mac<\/li><\/ul><ul><li>Your Apple ID, email address, and password.

Downgrading requires completely erasing your startup disk.

During the Recovery procedure, you don\u2019t want to risk erasing the Time Machine drive by mistake.<\/p>\n\n\n\n<h3 id=\"Step-Two-Prepare-a-Bootable-Installer\">Step Two: Prepare a Bootable Installer<\/h3>\n\n\n\n<p>Using a <strong>bootable installer <\/strong>is the most straightforward way to downgrade.<\/p>\n\n\n\n<p>A bootable installer is a USB flash drive that you prepare with macOS installation software so that the Mac can boot up from the flash drive rather than booting from its internal hard drive. Having booted from the installer, you can erase the internal hard drive, then install the earlier version of macOS onto the internal hard drive.<\/p>\n\n\n\n<p>To create the bootable installer:<\/p>\n\n\n\n<ol type=\"1\"><li>Attach the flash drive to your Mac. Use <strong>Disk Utility<\/strong> to format the flash drive as Mac OS Extended.<\/li><li>Download Apple\u2019s installer for the version of macOS you are reverting to. The installer will be about 14GB in size. In macOS, pull down the Apple menu and open the App Store. Search for the installer file for the version of macOS you want to revert to. Download it to your Applications folder on your Mac, but do not run the installer. It is also possible to download earlier versions of macOS from the Apple website; this is explained on Apple\u2019s support page below.<\/li><li>In the <strong>Terminal<\/strong> app, run the <a href=\"https:\/\/support.apple.com\/en-us\/HT201372#commands\" target=\"_blank\" rel=\"noreferrer noopener\">specific command provided by Apple for the version of macOS<\/a> you will be installing. You must enter the password for your user account with administrator privileges to run the command. The procedure will set up the USB flash drive with the necessary files, copy the macOS installer to the drive, and let you know when it\u2019s finished.<\/li><\/ol>\n\n\n\n<p>After creating the bootable installer, go to <strong>System Settings<\/strong>. Log out of your Apple ID account to disconnect your Mac from all your iCloud services.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#c9f0ff\"><strong>TIP: Software licenses, authorization, and activation.<\/strong><br>Your DAW, plug-ins, and audio apps may require license authorization or activation to your startup disk. After you downgrade macOS, these apps may see your new installation as a whole new computer, and you may need to reactivate each app. Before you downgrade, you should find out if you can <em>deactivate<\/em>&nbsp;or&nbsp;<em>deauthorize<\/em>&nbsp;each piece of software so you can use the license code to reactivate the software after your downgrade. Visit the developers\u2019 support pages for instructions.<\/p>\n\n\n\n<h3 id=\"Step-Three-Use-the-Bootable-Installer-to-Downgrade-Your-Mac\">Step Three: Use the Bootable Installer to Downgrade Your Mac<\/h3>\n\n\n\n<p>With the bootable installer connected and your Mac connected to the Internet, shut down your Mac.<\/p>\n\n\n\n<p>The procedure to start your Mac in Recovery Mode depends on whether you have an Intel-based Mac or a Mac with Apple silicon. Learn more at <a href=\"https:\/\/support.apple.com\/en-us\/HT211814\" target=\"_blank\" rel=\"noreferrer noopener\">Apple Support\u2019s article<\/a>.<a href=\"https:\/\/support.apple.com\/en-us\/HT211814\"><\/a><\/p>\n\n\n\n<ul><li>On an Intel-based Mac, power on the Mac and hold the Option (Alt) key.<\/li><li>On a Mac with Apple silicon, turn on the Mac and continue to hold the power button until you see the Startup Options window.<\/li><\/ul>\n\n\n\n<p>Select the volume containing the bootable installer.<\/p>\n\n\n\n<p>If you don\u2019t have an Ethernet connection to the Internet, you will be prompted to connect to your Wi-Fi router. The bootable installer needs to connect to Apple\u2019s servers for authentication.<\/p>\n\n\n\n<p>In <strong>Recovery<\/strong> <strong>Mode<\/strong>, accept the prompt to erase your Mac, or use <strong>Disk Utility<\/strong> to erase your internal hard drive.<\/p>\n\n\n\n<p>After the hard drive has been erased, select the option to <strong>Reinstall<\/strong> the version of macOS that is on this bootable installer.<\/p>\n\n\n\n<h3 id=\"Step-Four-Use-Migration-Assistant-to-Restore-Your-Data-from-Your-Time-Machine-Volume\">Step Four: Use Migration Assistant to Restore Your Data from Your Time Machine Volume<\/h3>\n\n\n\n<p>When your bootable installer finishes installing a fresh copy of the earlier version of macOS, it will boot to the <strong>Migration Assistant<\/strong> with a screen that prompts you to restore your data from a Time Machine backup.<\/p>\n\n\n\n<p>Connect your Time Machine disk to your Mac. Follow the prompts.<\/p>\n\n\n\n<p>Select the data from your user account on the Time Machine disk. Depending on how much data you have to restore, it may take hours to complete and could even take all night.<\/p>\n\n\n\n<p>Upon logging back in after your data is restored, Migration Assistant will prompt you to input your Apple ID and password to reconnect your iCloud services.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#f3f2f1\"><strong>TIP: macOS Audio Optimization<\/strong><br>You can continue to use your Time Machine backup disk to make incremental backups of your data from this point forward. But you need to turn off Time Machine backups while recording and mixing audio.
