Trying to update Mac OS from OS X Yosemite to MacOS Catalina but app store wont allow me Hi there I am currently running on OS X Yosemite 10.10.5 with my Macbook Pro Retina 13 inch 2013 model. I am trying to update to Catalina to use certain applications that require atleast 10.11 El Capitan or later. When I try to do it via the app store using my mac, I get a pop up to log in using my Apple ID and Password. It then asks "An Apple ID verification code is required to sign in. Type your password followed by the verification code shown on your other devices." I receive the verification code on my other devices but there is no place where I can type it in on my Mac. The pop up does not come up to allow me to input the verification code. Please help. I need to update my OS.

I had the same problem. The fourth try I turned off my VPN and it worked. Not sure if it was the VPN or the fourth try, but it finally worked.

Catalina cannot be verified and kicks me back to old platform. I have a 2018 13" MacBook Pro laptop
