Change the date in the terminal to December 2017. It should work.

Apple isn’t signing macOS High Sierra anymore. It’s like tricking the system by going back to when High Sierra was first released.

Got it, that explains a lot. Thanks!

Tried it, but it stays stuck at 2 minutes and then gives me the same error.

Maybe try installing High Sierra on a Mac OS Extended drive instead of APFS. APFS was still pretty new back then.

How do I make the drive Mac OS Extended? All I see are APFS options like encrypted and case-sensitive.

If you erase the drive, it should give you the option to format as Mac OS Extended.

Do I need to make a partition? The main drive doesn’t give me that option.

That’s strange. Did you click ‘View’ and then ‘Show All Devices’? Erasing at the top level should give you the option. APFS wasn’t mandatory until Mojave.

Oh, I see now. I’m new to Mac and still figuring things out. I’ll try that.

It says the erase process failed.

That’s not good. Maybe it’s the drive itself? Is this an older Mac with a regular hard drive? Try running First Aid in Disk Utility to see if it finds anything.

First Aid didn’t show anything wrong. I’ve been trying all day, any other ideas?

It’s odd that Disk Utility can’t erase or reformat the drive. I’m not sure what else to suggest. Maybe search for the exact errors you’re getting online?

Does it have to be High Sierra? Are you installing from a USB or the internet?

I’m using the internet.

Is the drive empty or is there data you need to keep?
