I'm trying to upgrade my Macbook Pro late 2011 from Sierra to High Sierra via this link:
https://apps.apple.com/us/app/macos-high-sierra/id1246284741?ls=1&mt=12
However, when it opens the itunes store shows this error:
To be safe I tried it with the Mojave update via this link here:
https://apps.apple.com/us/app/macos-mojave/id1398502828?ls=1&mt=12
and it gave me the same error. I read on this forum (and tried their solutions) that this might mean that it's not available for me to download. Where can I download the High Sierra update?
