Why won't El Capitan download on my Mac?
I am running OS X Yosemite Version 10.10.5 and tried to download El Capitan Verision 10.11.4, but it will not download. When I click on the "Download" button, it stays on "Downloading" for a few seconds and then it kicks it out and won't download. It seems that that cursed shower (evil software) tries to prevent the download because it would be eliminated. It would be greatly appreciated if anyone would be able to help with downloading El Capitan successfully. This is the first time I have had any difficulty downloading software update.
