i got message "OS X Yosemite failed to download" "Use the Purchases page to try again."

I'm trying this now. Will know in a few hours if it works.

Hi guys! To resolve your issues regarding unable to download Yosemite, please follow these steps:

1. Delete the OS X Yosemite file on your Applications.
2. Sign out from App Store.
3. Open Finder > Click on Go > press and hold the Option/Alt key on your keyboard
4. Click on Hidden Library
5. Open Application Support folder
6. Locate App Store folder and move this folder to trash
7. Open Preference Folder
8. Move com.apple.AppStore.plst to trash
9. Restart your computer

This will allow the computer to remake those preferences files for the App Store and should let you download the 10.10 upgrade without any issues at all.

Thank you! The free trial of Cloak worked! I have Yosemite. WOOHOO! I hope when I have to shut down later I still have it when I log back in.

Tried but does not work on my system.

Tried but does not work

I encountered this and tried a lot of methods stated here. I was then using my iPhone5S as my internet source. I connected to a different wifi network and the download and installation were successful. I hope this works for all of us. 🙂

Does not work!

abelq's suggestion worked perfectly for me, it took only a few hours , loaded and installed, is still working this next day, after shutting down and re-starting. Abelq suggested getting this app, https://www.getcloak.com/ - 30 day free trial. I did, that was the only thing that worked.

this did not work for me. 😕

It works by changing DNS to 8.8.8.8 and 8.8.4.4.

I have the exact same problem on my 2009 MacMini. same message and telling me to go to purchases. I changed the DNS but still not working. Is there another trip? Will try rebooting everything one more time but....

ANY HELP IS APPRECIATED!

Abelq's suggestion worked beautifully for me, nothing else did. Here's the suggestion:

I have met this issue and I solved by study somewhere here with two simple steps:

1- Create a other admin account

2- Log in buy the new account.

Download function will run nomally for Yosemite

After dowload you may know:

- Copy the downloaded install file.

- Login using old admin account

- Upgrade...... completed

Hope may work for almost of you. I think the fault come from my changing in some setting regarding to download software from not App application or App certify
