Directly download new major release of macOS from Apple server and install it from your local Mac machine

The download manager of App Store application seems does not allow resumption of interrupted download of macOS installer. If you have a very slow internet connection or it disconnect for a while, the download will fail due to connection timed out and the downloading of macOS installer will not resume and it also does not provide a "resume" button to continue the download. You will need to restart the update and the download will begin from zero percent again. This is frustrating for Mac users who do not have fast internet every time they update their macOS.
