Can’t sign in to app store even though apple ID and password are correct
Background: Pulled an old MacBook Pro Retina 13” (mid 2015) out of storage, blew the dust off of it, and re-installed Mac OS X Yosemite via the recovery partition and over our network. Successfully logged in, connected to my iCloud account, applied software updates that it wanted. No problem.
THEN … I tried to log in to the App Store. Both of them complain my Apple ID or password are incorrect - but at the same time my iPhonme pops up the standard alert asking me to approve the new device on my account (exactly as it did when I logged into iCloud). The prompt to enter the verification code never appears on the MBP though. That convinces I did enter my password correctly, otherwise an approval message wouldn’t have gotten sent.
What should I try next? Set up a new AppleID from scratch?
