AMD-Action:downloadProduct:SP

Had this problem as well once I was deep into the process and could not log into the App Store.

Here is what worked:

1. On another Mac computer I own I logged out, then into the App Store.
2. On the Mac I was having this issue with I went into Internet Recovery (power on or restart and hold Command-Option-R immediately when you hear the startup chime). Keep holding until your see the Starting Internet Recovery globe icon. You should then get prompted to join a Wi-Fi network if you are not on wired Ethernet. Once joined, you should see a progress bar, then the OS X Utilities screen, where you can choose Reinstall OS X. It can take quite a while for this to appear, since it is loading from Apple's servers over the Internet.
3. This time the AMD-Action:downloadProduct:SP message did not show up and everything proceeded normally.

Hope this works for folks.

Got this from Cory Cooper posting on Mac-help.com - Many thanks Cory!!!

hi rohitraodetmold

I have same issue with you before, you have to log in to your Apple ID through iTunes, the problem will be solved. Enjoy your Mac :)

Hi, I just had this problem too. What worked for me is logging out from the app store (forget iTunes..) and then log in again. Then it worked. Did you find the right link to the software?

I had the same error while downloading High Sierra. I logout out of iTunes and The Apple Store. Logged back into The Apple Store and was able to download and install High Sierra without a glitch.

You may  have adware/malware installed. Try downloading this program which was written by Thomas R, a long time poster. The program will search for malware/adware. The program will do the work for you which makes it easy. It may be necessary to run more than one scan. After running the scans, restart the computer.

Malwarebytes Anti-Malware for Mac      10.10 and later

Malwarebytes uninstall

Try booting into Internet Recovery (command - option/alt - R on a restart). It is a slow process. This will install the newest OS that the computer is compatible with. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Quit Disk Utility. Then install the OS. When the computer restarts, you can use Setup Assistant to restore your data from Time Machine.

OS X Recovery (2)

If you click Cancel, does Sierra download? Have you tried downloading Sierra in another admin account and/or the Safe Mode?

Safe Mode - About

Go to System Preferences, click on App Store,at bottom of page under free downloads uncheck password required

yes the iTunes sign in worked

hi,

i have the same problem. How can we log in to our Apple ID through iTunes when we are in the Utilities option? Doesn’t mean that we’re stuck on that and cannot access to any applications? Sorry for my missing knowledge , I really need your help. Thanks very much

What Utilities option are you in? If you are booted into the Recovery Partition, you can't sign into iTunes from there. Can you reboot normally and sign into iTunes?

Open the iTunes application and sign in.

Same problem. Three weeks ago I installed Sierra on an external drive, now I can´t download the file anymore. Checked on malware but I haven't found anything. Can I download the installer file somewhere else?

Same problem: New HD, so downloading Sierra base system is my only option. I have no other OS to access App Store etc. Wish they still did hard copies of OS. [The old HD corrupted my TM Backup, so no joy from TM. Why didn't TM tell me my backup wouldn't be usable????
