HOW CAN I BE HELPED IF MY MACBOOK PRO IS A 2010 VERSION BUT HAS 7i CORE

The MacBook Pro 15” and 17” models from mid 2010 both offered models with various Intel Core i5 and Core i7 processors.

All MacBook Pro 15” and 17” models from mid 2010 are supported with macOS 10.13, and are not supported with later macOS versions.

Mostly you just need a more modern Browser than Safari on Mojave, or High Sierra like Firefox or Brave.
