While macOS Catalina is scheduled to be released sometime around September, the public beta is already available, so everyone can try all the new functionality without the wait. Read through our step-by-step guide to learn how to install macOS Catalina public beta.
Regardless of whether you want to install the beta or wait for the official public release, one question will inevitably pop up in your head — is my Mac compatible with macOS Catalina? Good question! Let’s look at the Mac OS Catalina compatibility chart to find out.

But don’t hurry to the Apple Store just yet. If watching videos in 4K is not an absolute necessity, you could simply optimize the Mac you have for faster performance and run macOS Catalina without a problem.

Luckily, there's a software designed to take care of it all automatically.

Once you clean your Mac from all the system and user-generated junk, you’ll notice improvements in responsiveness and speed right away. But it’s not only outdated files that slow your Mac down.
To hit all macOS Catalina system requirements, you need to have as much of your hard drive free as possible. This might include, for example, legitimate but long-forgotten documents you haven’t opened in years.
The good news is you can see what’s taking up your hard drive capacity with a new feature in CleanMyMac X called Space Lens, which creates an interactive visual map of all your files and folders:
