MacOS high sierra download error message in installer
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,
