Why can't I upgrade macbook OS from EL Capitan to High Sierra or Newer?
I have an early 2015 MacBook Pro Retina 13 using El Capitan 10.11.6. Im trying to upgrade the OS to High Sierra or newer. I have clicked the links to the OS upgrades that have been provided in answers to other peoples' questions. Nothing happens. It takes me to a blank page on the apple website. Are the servers down? What is wrong?
MacBook Pro (2020 and later)
