If you upgraded to macOS 10.15 Catalina and experienced problems with macOS, the software, or connected devices, then one or more may be incompatible with each other. While software may appear to work, or even sort-of work, you should wait to upgrade macOS until your software and devices are officially supported by their manufacturers. New versions of macOS often “break” 3rd party software like DAWs, plug-ins, and audio/MIDI device drivers. Before doing any of that, consider whether or not downgrading macOS 10.15 Catalina at all. If you decide to downgrade macOS, make sure you back up your files either manually or via Time Machine. Upgrading macOS is generally a good idea unless it means making your devices and software incompatible with your Mac.
Follow the steps below to back up your Mac, erase the startup disk, and then reinstall macOS. New Macs that ship with 10.15 Catalina pre-installed cannot downgrade to 10.14 and below, though future upgrades can be undone by downgrading back to 10.15 Catalina. Any compatible Mac that can upgrade to macOS 10.15 Catalina can also be restored to another compatible version. If you’ve recently upgraded your Mac’s operating system to 10.15 Catalina and need to go back, this is the guide for you.
