I'm running Sierra on a mid-2010 (11,2) iMac and would like to upgrade to High Sierra 10.13 but can't find a valid download link in the App store. Any help?
iMac 21.5", macOS 10.12

See if you can boot into Internet Recovery Mode using Command + Option + R.
It is possible you may have a failing hard drive which is corrupting your download. You can run DriveDX and post the report here using the "Additional Text" icon which looks like a piece of paper.
Try the link posted by BDAqua in https://discussions.apple.com/thread/251020320
Try downloading from this link in Safe Mode:

Tried to use the link you provided but get the following pop-up... "This copy of the install macOS is damaged, and can't be used to install the macOS.
I've seen that message come up when there's already an installer on your Mac. Check in your Applications and Download folders and if there's an installer delete it. Then try again.
Same link, same problem
Thanks. Any idea what the file name or extension would be? Sorry if that's a newbie question, but I'm a Mac novice.
It would be "Install Mac OS High Sierra" probably .dmg.
No macOS installer files in either Applications or Download folders.
Thanks macjack, but same pop-up when I tried in Safe Mode. Any more suggestions? Thanks
I'm not sure what to try next. I even tested the link myself and it was able to download and open the installer on my Mac.
Is your Date & Time set correctly?
Thank you! This worked for me.
