Hi there,
I tried updating from Sierra to High Sierra. The link directed me to the App Store and when i open the installer, the following message popped out:
This copy of the Install macOS High Sierra application is damaged, and can‘t be used to install macOS.
Is there any other way to download High Sierra? I cannot update my Mac without updating to High Sierra.
Any advice is much appreciated.
Regards,

High Sierra can only be downloaded via the App Store.
What do you see when you connect to the High Sierra page, do you see Download or Get,
or do you see Open. If you see Open then the App Store has detected that there is a copy
or partial copy of High Sierra on your Mac. Look in your Applications folder for Install macOS High Sierra.app
if it is a complete download it should be just over 5GBs. If it is a partial download then put it in the Trash and
empty the trash. Try again.
If you can connect your Mac to your router using a cabled connection rather than WiFi.
