Okay, sorry, maybe I wasnt clear, I will try again:
My goal: All I want to do at this stage is log in to appstore with my apple ID (which I created in the browser and by now I have 2 phone numbers as second factor), so I can download and install Catalina. Logging in to apple ID on the browser works well and I get SMSes to verify, no problem.
Current situation:
- I have a clean installation of Yosemite
- I user on the Imac but I could not register the user with an apple ID because during installation I was told there was a server error.
- I have a working Apple Id
- I suppose I have no icloud keychain, because I have never used icloud, seein as I have not done anything with my apple ID besides registering one
- When I try to log in to icloud or connect an icloud account in the system preferences, it never works because I do not receive a verification code via SMS but the mac asks for a 6 digit verification code
- If I find Catalina to download on the appstore and click download, the appstore asks me to log in again, here the problem is slightly, curiosly different: I give my email and password, the appstore tells me the password or email are wrong, BUT I do get verification codes send via sms, but here I csnnot enter them anywhere, because the appstore doesnt recognize my credentials
So if I can set up the keychain somehow or hook up my android phone so that the verification code is given to me there instead of an SMS, that is fine for me, I just dont know how to.
