I need it to upgrade from mac OS High Sierra Version 10.13.6 so I can keep my internet security. the company said I needed to upgrade to Mojave but I have tried everything but the App Store will not let me to do this.
my iMac is a late 2013 model.
Any help would be greatly appreciated
iMac 27″, macOS 10.13
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...
If you’re short of bandwidth or data… 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.

Well hubby decided to take the iMac to a computer person since nothing was working. They had a look and there is no way to update the macOS as Apple have stopped use of it. The only way to do it is through another website he told my husband that that can cause other issues and may not be a good version or something. Anyway hubby said no. We will call into our local Apple Store speak to someone. If it can’t be done through Apple we decide what to do from there 😳🙄🤷🏻♀️
Thank you very much, will try your suggestions 😊
Do keep us tuned in my friend! :)
Best of luck my friend...
I need macOS Mojave 10.14 but the version in the App Store says it is corrupted and won't download.
