2013 21.5” desktop yosemite
I have an older model, 21.5 inch desktop 2013 model. I have wiped the hard drive off and downloaded Yosemite 10.10.5 back onto the machine. That is the original OS for this computer. In setting the machine back up I cannot log onto the App Store. When I put my password in it says incorrect password. I am 100% certain it is correct. I have signed out of iCloud, closed the applications and restarted the machine, signed back into iCloud and attempted to sign into the App Store with no success. Every time I try to sign into the App Store. I get a ping on my phone about another device requesting to login. I hit accept and receive a two factor authentication code, but I am never ask for it in the signing process. Ultimately, I would like to upgrade to a newer operating system, but cannot seem to get anywhere.
