I notice the app store only offers the latest OS for free download, which is now Yosemite, but I would like Mavericks as well, but I don't see it in the app store. I noticed that I tried downloading the mavericks installer once before to my hard drive, but when I go to my applications list, and under the tab of size, there is just a white bar, like when something is being downloaded. All the other installers; Yosemite, and mountain lion appear normally, with their sizes listed. Did something go wrong with the installer? that is why I am asking where I can download it to see if I can get a clean right download. I also notice on the launchpad icon on my dock, there is a faint white bar across the lower half, like when there is a download, is this normal?
