Apple’s Catalina operating system brought many new features, but not all users are thrilled with the changes. Many Mac users are considering downgrading from Catalina to Mojave for a more stable and familiar experience. In this comprehensive guide, we’ll explore why you might want to make the switch from Catalina to Mojave, how to downgrade your system safely, and what you should expect during the process.
Downgrading from Catalina to Mojave can be beneficial for several reasons, particularly if you’re dealing with compatibility issues or simply prefer Mojave’s more familiar environment.
One of the most common reasons for downgrading from Catalina to Mojave is software compatibility. Catalina dropped support for 32-bit apps, which means many older applications won’t work. If you rely on these programs, switching back to Mojave is your best option to continue using them without issues.
Many users have reported slower performance and increased memory usage with Catalina. Mojave is often seen as a more stable and faster alternative for certain older Mac models. If your Mac has been sluggish since upgrading to Catalina, going back to Mojave might resolve these issues.
Catalina replaced iTunes with three separate apps: Music, Podcasts, and TV. If you’re used to managing everything within iTunes, the switch can be jarring. Downgrading from Catalina to Mojave will restore iTunes to your system, making it easier for those who prefer an all-in-one media management solution.

Before you begin the downgrade process from Catalina to Mojave, it’s important to back up your data. The downgrade will erase your hard drive, so you’ll need a Time Machine backup or another backup solution to restore your files afterward.
To downgrade from Catalina to Mojave, you first need a bootable installer. Here’s how to create one:
sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume“
Once your bootable installer is ready, it’s time to erase your hard drive. Here’s how to do it:
Now that your hard drive is clean, you can install macOS Mojave:

After installing Mojave, you’ll need to restore your data from a Time Machine backup or manually transfer your files:
Once you’ve successfully downgraded from Catalina to Mojave, your system should feel more familiar and responsive, especially if you were dealing with performance issues on Catalina. Here are a few things to keep in mind after the switch:
With Mojave, you’ll regain the ability to run 32-bit apps. This is particularly important for professionals or hobbyists who rely on older software that hasn’t been updated for 64-bit systems.
If you missed iTunes after upgrading to Catalina, you’ll be happy to know that downgrading to Mojave will restore the full functionality of iTunes. You’ll be able to manage your music, podcasts, and TV shows in one place again.
While Mojave is more stable for some users, you’ll lose access to Catalina’s newer features, such as Sidecar, which allows you to use your iPad as a second display, and enhanced security protocols. Make sure you’re comfortable giving up these features before committing to the downgrade.
While many users experience a smoother ride on Mojave, downgrading isn’t always without its challenges. Here are some potential roadblocks:
Some newer applications are optimized for Catalina and may not run as smoothly on Mojave. Be sure to check the system requirements of your most-used apps before downgrading.
If you don’t back up your data correctly, you could lose important files during the downgrade. Always make sure to double-check your backups before proceeding.
Deciding whether to downgrade from Catalina to Mojave depends on your personal preferences and how you use your Mac. If you’re experiencing performance issues, software compatibility problems, or simply prefer the stability and familiarity of Mojave, then downgrading may be the perfect solution. However, if you rely on Catalina’s newer features, it might be worth sticking it out or finding workarounds for the problems you’re facing.
Ultimately, both Catalina and Mojave have their strengths, and understanding the trade-offs is key to making an informed decision. If you’re unsure or need help with the process, contact Kingfisher Computers for expert advice and support.
