A couple of weeks after launching the third beta of macOS Catalina and a day after seeding the fourth developer beta, Apple released the third beta of the upcoming macOS Catalina update to public beta testers.
All beta testers who have signed up for Apple’s beta testing program can download macOS Catalina beta 3 via the Software Update mechanism in System Preferences after installing the right profile.
Anyone who wants to participate in the Apple’s beta testing program can sign up via the beta testing website.
As with all betas, Apple advises the potential beta testers to make a full Time Machine backup before installing macOS Catalina. Also, testers should keep in mind that installing the update on a primary machine is not recommended as betas usually have many bugs.
Apart from the new features, users need to know that 32-bit app support will not be available on macOS Catalina meaning that many of the older apps could potentially stop working if they’re not updated to 64-bit.
Alongside the third public beta of macOS Catalina, Apple launched public betas for iOS 13, iPadOS, and tvOS 13, which are also distributed via the company’s beta program.
