Verification code issue on 2015 MacBook Pro
Hello everyone,
I am using a 2015 Apple MacBook Pro running OS X Yosemite (version 10.10.5). Unfortunately, I’m unable to use updated versions of Microsoft Office, Chrome, and other software due to the outdated operating system.
I recently erased the MacBook, which I purchased second-hand, and tried to sign in with my own Apple ID. However, during the sign-in process, it asks me to "enter the verification code sent to your other device," but I don’t have access to another trusted device to receive the code.
As a result, I’m stuck and unable to move forward or go back. My MacBook is essentially unusable at this point.
I’d greatly appreciate any advice or solutions you can provide to resolve this issue.
Thank you in advance!
