Research macOS Catalina Feedback
If you aren't installing the macOS 10.15 beta on day one, you can look at feedback from developers and other users trying the developer beta before you upgrade.
This will help you understand how macOS 10.15 runs on specific Apple devices and find out about any problems with the installation and upgrade process that users ran into.
We recommend everyone look into feedback from users on Twitter and in the MacRumors forums, but this is especially important if you are on an very old Mac that is just barely included in this update.
