I just purchased a new Imac 27" this past week to replace my aging Mac Pro (2008) ...I used time machine to restore my sTtuff...I did a few updates which went fine...I did have a problem with my Apple ID not being recognized in Itunes and it forced me to change the password..I tried to update to the new OS and I keep getting an error message "Unable to complete purchase" or something like that...(Im at work)..I googled and tried numerous solutions to no available..(deleting * .comapplestore.plstect.) I wont even update Pages or anything getting the same error. Is there a way to D/L the new OS apart from Update or AppleStore but still from Apple, with the hopes it can fix the error by overwriting something...I cant even reinstall Sierra, as I get the same error message(s)..I think the problem is the Apple ID/Password but I can log into Itunes Store and Appstore and see my accounts from both....Anhy ideas...I have rebooted after each "Fix" attempt, and used First Aid on the drive (Fusion)....THanks
Got a tip for us?

Do you have access to another mac running El Capitan? If yes, you could use that Mac to download the sierra update, don't install it right away, create a Sierra USB installer, and then either install Sierra or quit.
You could also search for a downloadable Sierra dmg file. The file should be around 4.1 GB.

I have a MacBook Pro (Sierra), not with the .6 update, so that should work..I was not aware the updates were saved...Thanks...When I get home, Ill try it, hopefully it will fix it for me....
The new iMac is already running sierra? If yes, try updating via an Apple comboupdater: https://support.apple.com/kb/DL1931?locale=en_US
It is and Im downloading right now...Thanks, the both of you...Ill post how it works(ed) out !
OK....That didnt work...but this little diddy had me up and updating in a few minutes...I wish I can credit the genius who compiled this, but I dont know who it was, but it worked.
" I got the same "failed to download" error message with a couple of different app updates and an app re-install. After spending a couple of hours investigating it, I hit upon a combination of steps that worked for me. Here are the steps I followed:
Step 1. Reinstall iTunes.
Download and reinstall current version of iTunes (which is currently version 12.6.2). Here is the link: https://www.apple.com/itunes/download/
Step 2. Change your DNS setting.
Here’s how to do that: Go to Network Setting in Settings Preferences. Select your network connection, click Advanced in the lower right-hand corner, then click DNS in the top row of options. At the bottom of the left side pane titled “DNS Servers:” click the plus (+) button and 0.0.0.0 should appear as the first line in the window. Type over it and change DNS to a different setting.
One possible DNS setting is Google’s 8.8.8.8 or 8.8.4.4 DNS settings. You could also insert one of these OpenDNS settings: 208.67.222.222 or 208.67.220.220 on the first line.
Just for the record, I used a different Cox Communications (my Internet provider) DNS setting: 68.105.28.11
Step 3. Clear the App Store cache.
Open the Terminal utility (in the /Applications/Utilities/ folder) and run the following command:
open $TMPDIR/../C
A Finder window will appear that shows a number of folders. Locate and delete the folder named "com.apple.appstore," then empty the trash.
Re-start your Mac, allow all background startup processes to finish, then try launching the App Store and purchasing or updating the application again. Hopefully, it will download and install without any error messages.
Step 4. Optional: Clear the DNS setting you previously set.
It’s no big deal if you leave the DNS setting you selected but if you want to restore the default setting, simply repeat the steps in Step 2 above. Click on and highlight the DNS setting you previously typed in, then hit Delete. Close the windows and your network settings will automatically reset to the default settings (which on my Mac is to default to the Airport Extreme setting: 10.0.1.1). You may possibly have to restart your Mac.
These are the steps I followed on four out of five Macs that gave me the App store "failed to download" error for different updates and app re-installs. These steps worked for me and I hope they work for you. Good luck!"
