OSX Yosemite Failed Download I'm trying to install OSX Yosemite.  I start the download from the app store and it sit and thinks for 40 minutes or so and then gives me the following error:

Yosemite Failed to Download
Please visit the purchases page and try again.


How do I make this work?  I've tried the download twice now,
You do not have to just wait, you can see what is it doing.

From the Mac App Store, click on the “Purchases” tab to see the active list
Locate the app(s) you are downloading that you want to check


This will show you the download progress bar, the total downloaded out of the total download size, and an estimation of time remaining until the app has completed downloading and is ready for use.

Meanwhile you can clean the temporary download:

Run this command on the terminal: open $TMPDIR../C/ ... 

It will open up Finder in a specific folder, you select com.apple.appstore and delete this folder.
