How to Downgrade macOS 10.15
If you’ve in recent times upgraded to macOS 10.15 Catalina but the new operating system hasn’t worked for you for different reasons you can always downgrade macOS 10.15 to an earlier working operating system such as 10.14 Mojave. Note that if your Mac was bought with Catalina already installed downgrading it is virtually impossible. To downgrade from macOS 10.15 to macOS 10.14 you must have upgraded to Catalina from Mojave or other earlier version. The downgrading process doesn’t have to be complicated in any way. Here are a few pointers on how to do this.
Do You Really Need to Downgrade?
No one really wants to downgrade to an inferior macOS when they can use the latest and freshest with new add-ons. However, even while upgrading is a wonderful choice, it might cause problems such as affecting third party applications on your Mac, including device drivers for video or audio, among others. Go ahead with a downgrade from macOS 10.15 to macOS 10.14 if you’ve ascertained that the upgrade has actually led to diverse issues on your Mac hardware and software.
At times, the problem mightn’t be macOS Catalina itself but software compatibility complications. If software is incompatible, simply resolve the matter by updating it or deleting it from your device and then go ahead and re-install the application that works with Catalina.
Nonetheless, don’t just start the downgrade; it could be a general problem that Apple might have already addressed. For instance, there could be a new update already released that once installed easily corrects the problem. Where compatible or working fixes aren’t available you could wait just to hear about macOS Catalina update releases which Apple usually does soon after the release of an operating system.
Also, do ensure your Mac version is actually compatible with new 10.15 Catalina since a good number aren’t supported. Also, Apple announced that 32-bit application support will no longer be there in Catalina and you need to ensure that all your applications are 64-bit to avoid downgrading for nothing.
What You Need to Do before Downgrading macOS 10.15
Note that to downgrade from macOS 10.15 to macOS 10.14 you need to ensure your Mac has been erased, which means losing everything if you don’t back it all up.

For those without Time Machine back up it’s important to have a snapshot of your plug-ins, applications and other software you might need to reinstall later. For software with licenses the license also need to be backed up or removed.
It’s important to ensure all copies or first copies of your documents have been backed up to the cloud or external derive.
