Hey guys, So when I discovered I didn't need Mountain Lion (10.8) to bridge the gap between what I currently have installed (10.7.5) and Mavericks and wouldn't lose anything by skipping buying 10.8 (not to mention apple doesn't seem to sell it anyway) I decided to go from 10.7.5 straight to 10.9. So find mavericks on Apple.com, click the link to take me to the App Store app, and then hit download>install app through App Store. However, nothing really happens. No confirmation or action is visible (ex. in safari when you click to download something the icon zooms over and the download pane shows its progress.) When I go to purchases I see Mavericks there, but the grey box is mysteriously blank and no matter what I do (restarting App Store, signing in and out, restarting computer) nothing is fixed. Did it bugg out on my App Store App? Has anyone seen this before? Help Please! Thanks for any and all responses. Here's a pic of the problem.
