OS High Sierra

Hi,


I'm using a MacBook Pro (late 2011) with OS 10.12.6 Sierra, but I need to upgrade to 10.13.6 High Sierra. When I follow the apple links to the App Store page for High Sierra and click the Open tab I get the following message This copy of the Install macOS High Sierra application is damaged, and can‘t be used to install macOS.


Any ideas what I can do? I can't use a more recent OS as my Mac won't support it, but I need to get 10.13. I can't seem to find another download for High Sierra.


Any help (beyond saying get a new Mac) will be appreciated.


Thanks

Steve

Go yo your Applications folder and your Downloads folder. Find and delete any previously downloaded installers ("Install Mac OS High Sierra") then restart and try again.
