how to download macos high sierra?

I just went through this! Once downloaded and installed/copied into applications then go to contents and delete the file “installinfo.plist”. This will get rid of the expiration and will no longer show damaged.

Hi Wai79,

Here is an Apple Support Article about how to install macOS High Sierra on your device.

I hope this helps.
