Apple released the first beta version of macOS Catalina 10.15.5 for developers a week after the release of the public build of macOS Catalina 10.15.4. The new macOS Catalina test build can be downloaded by users with a developer profile installed in the System settings. The update includes performance improvements, security updates, and bug fixes found in previous OS builds.
Anyone who is lucky enough to have installed an active beta profile on your computer can take part in the testing.you can download it from this link. However, for our part, we strongly recommend that inexperienced users who have not previously participated in the beta testing program do not do this, and even more so install the test build on the main computer.
