How do I upgrade to high sierra from snow leopard
I have a mac book pro 8.1 with latest snow leopard. I want to upgrade to high sierra the most the macbook pro will support.
To do this I have to install el capitan then sierra then high sierra.
To do that I need to use the app store to download.
To do that I need an apple id.
I created an apple id and tried to sign into the app store but it says to change my payment details (new account ???)
i need the latest os x which my mac book pro does not support.
So how do I upgrade to high sierra either without using the app store or how do i get around the restriction of needing mojave to do so.
MacBook Pro, Mac OS X (10.6.8), null
