Mac – Error logging into App Store – AMD-Action:authenticate:SP

email me

I came across this error when trying to upgrade from El Capitan to Sierra (setting up a very specific dev environment). Method 1 resolved my issue.


Method 1 (dual authentication issue)

Download something from the app store (a small app) and authenticate.
Try downloading the larger app/OS file now.


Method 2 (date issue)

Command + R at Mac startup to enter Recovery Mode
Utilities > Terminal

date mmddHHMMyy (Pacific Time)
csrutil enable
csrutil clear

Reboot and try downloading the larger app/OS file now.


Method 3 (privilege issue)

Change permission for the Users Shared folder

sudo -s
cd /Users
ls -al
rm Shared
mkdir Shared
chown root Shared
chgrp staff Shared
chmod 775 Shared

Try downloading the larger app/OS file now.
