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

😉I don't have an answer but from what others have posted about Yosemite there is plenty of server traffic that's causing delays. I would quit the download and wait for an hour or two and try again, Thats only my opinion if it happened to me😉

This is happening to me too; my download gets to 860mb, anything after that, it goes back to 860mb then fails.

Any ideas?

I'm having the same problem, except the download reaches 100% and then fails. I've downloaded 6 times entirely, and even found the temporary download files buried in /private/..., which I deleted and attempted again. Failed. Fails at 100% every time and I really can't attempt again until I know the solution, because my bandwidth cap from my ISP is getting eaten away.

Has anyone solved this problem? I'm getting the exact same error message with my MacBook Pro 13inch. I've been trying from 12am - 5am. Servers can't be backed up that long. Please help!!!

Same thing happening to me. Tried rebooting the system, It started from 0 again but again failed at 870. After clicking retry it started from 860. Have you tried doing this?

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. If you check the size of this folder, it's exactly 860.X MB 🙂 I think this is the culprit, somehow it got corrupted and the system don't know what to do with it.

PS: I haven't tried it out yet.

Thanks,

I am also facing the same problem. My download is not even starting. Just after clicking download it shows the error "OS X Yosemite failed to download Use the purchase page to try again". I am using MacBook Air 2014.

I experienced exactly the same thing. But download fail right after i click download on the purchase page. And it happens 18 hours after the launch of Yosemite.

Macbook Air, Mavericks

Just solved the problem by calling the apple customer care. They just told me to put new addresses on DNS & it just worked for me.

Can you please explain this in lamens terms? I don't even know what DNS is.😕

To change your DNS to Google's DNS (DNS being the server that tells your computer what a domain like "apple.com" means in terms of numerical IP addresses) go to System Preferences > Network > Advanced > DNS.

Add either or both of the following entries into "DNS Servers":

8.8.8.8

8.8.4.4

Did it and reattempted to download, but still no solution for me.

I've already burned through about 35GB of my bandwidth cap, so I guess I'm giving up until a solution is found for my problem of it getting to 100% and then failing.

Make sure you have sufficient charge if you are using a Macbook or similar.

OS X Yosemite failed to download for me until I had charged my Macbook Pro.

This seems to be working for me. VPN using https://www.getcloak.com/ - 30 day free trial. Crossing my fingers since the download isn't done yet.

I had a hunch that my ISP was the culprit. I cannot download anything from the appstore that had more than 1 gig filesize. Xcode, mavericks, yosemite. They would all stop and give the "failed to download....use purchase page..." error the moment the appstore starts downloading.

None of the changing DNS, emptying of cache, on/off appstore, or restarting worked.

I'm on an iMac, Maverick.

I Think I found the problem. It's something to do with the internet your using. My job Internet would not let me download more than 860mb but when I downloaded Yosemite at home it works fine. Try another Internet connection.

Yosemite download failed twice on me. I have a late 2009 iMac. But worse, Apple had updated several apps in preparation for Yosemite, so they wouldn't work either. I had to reload the older Maverick versions of iPhoto, Pages, Numbers and Pages. I'll update if Yosemite ever downloads properly.
