I have Mac OS 10.14.6 and I am trying to upgrade to 10.15.6 and the download always fails stating that the network connection failed or the gateway is bad. It appears I need to download 10.15 to move the upgrade, but only 10.15.1 is online.
Is there a way to past this error message when trying to download the update? I can download 8 gig files no problem, the update always fails. Is there anywhere I can get Mac OS 10.15 so I can step the upgrade process through the support download site? All that is available on the download site is 10.15.1 - 10.15.6.
