MacBook Pro won't update to High Sierra.
After research and checking, including here in this forum, I decided to update to High Sierra but my (oldish) MacBook Pro doesn't seem to agree. I have been through the motions twice and everything seems to happen normally but this is what I end up with: macOS Sierra Version 10.12.6
If I understand things correctly, this is not even High Sierra, let alone the latest version.
Here are are my Mac's official details: MacBook Pro (13-inch, Early 2011)
Any explanations please?
iOS 11.0.3
