Receiving an error while downloading the Catalina's update Dear specialist, I tried to update my macOS from Mojave to Catalina many times, but every time that download process has been finished, I will receive an error: "The update could not be verified. An error occurred while installing the selected updates.". Furthermore, I tried to download that manually from https://support.apple.com/downloads, but this link contains 10.15.1 and 10.15.2 versions of that, which both of them requires macOS version 10.15. to install. Please guide me to install 10.15. version of macOS manually or please tell other ways to install that. Thank you in advance.

Open the App Store and search for Catalina. Use that to install the upgrade.

You are trying to use an update to install the original OS. That doesn't work. You must upgrade the OS before you can update it.
