I started an OS X Yosemite download. I did not want to download it or install it; rather I just wanted it to show up under purchases so I could install it in the future after Apple removes it from the App Store. It will avoid problems like Where can I get a copy of Mavericks after Yosemite has been released?
The Pause button is not available (its greyed out), so I can't pause or stop the download.
How do I abort the download now that the "purchase" has been made?
