Hi., I and currently running OS 10.13.6 (High Sierra). I found the Mojave download page at the Apple App Store (10.14.6), but when I click the "open" button, I get this message: "This copy of the Install macOS Mojave application is damaged, and can't be used to install macOS." My machine is MacBook Pro (retina 15", early 2013), which I understand is supposed to be compatible with Mojave. Any help would be appreciated. hanks.

Delete "Install macOS Mojave" from the Applications folder and try the download again while in Safe Mode.

If you get a corrupted message...
Naw, it's not damaged, it's just that you have an old copy already in Applications, there are 2 cures...
Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS Mohave App in Applications, so expired Certificates are not expired.
Or... trash the Install MacsOS Mojave.app in Applications then a new copy can be downloaded.
Tried downloading in safe mode. Got the same error message.
Thanks for the help. I deleted the old install mojave app, then dowloaded the new one in safe mode. Mojave has successfully installed & id now up & running !
You're welcome.
