I am trying to update my OS to High Sierra on my older iMac 5K
None of the links shown here on Apple ( https://support.apple.com/en-us/HT211683 ) for downloading High Sierra go anywhere. I am trying to upgrade the Sierra OS on this machine to High Sierra and not finding anyway to access the software. I cannot go to a later OS at this time as I need to migrate some data first. Any ideas?
iMac 27″ 5K, macOS 10.12
