update from high sierra to mojave

Download macOS Mojave

Visit the macOS Mojave page on the App Store, then click the Get button. After downloading, the installer opens automatically.

Get macOS Mojave from the App Store

Upgrade to macOS Mojave - Official Apple Support

JUST be SURE you are getting Mojave and not Catalina 64 bit only with many issues!!!!

I have the same problem as the poster - when I follow your first link to the app store I get this popup: "this copy of the instal macOS Mojave.app application is damaged, and can't be used it install macOS." I have High Sierra. And at this link https://support.apple.com/downloads/mojave 10.14 is not listed (though all the other versions are listed).

As I couldn't download 10.14, I downloaded 10.14.1 - but it says I need 10.14 (I guess that is obvious) first.

Any suggestions?

I checked the link you posted and the versions are all there but since you had an issue with the other link stop trying for now and click........Contact Support.......at the top right on this page for help.

Hi leroydouglas looks like I am missing some info you can help me with, I thought that when you download the OS it runs automatically but looks like from your answer that is not always the case, can you please explain.

Thanks !

The solution from Apple Support: go to Applications folder and find > Install macOS Mojave. Move that to the trash then go to app store and try downloading again. It appears to be working! No more "damaged" message. @traypup

(I had no idea that file was there, dated 2018, might have automatically downloaded at some point as I never consciously did it; don't have autoupdates enabled but at any rate, here we are).

@fyip thanks for your help

Welp so this happened. (Seems I had alegría de burro as we say on Spanish - false hope).

Any instructions you follow via app store or apple support takes you to

the download Mojave button - and the file is always "damaged" - I spent

several hours with Apple support over the weekend, we walked through

every scenario including making sure any files such as Install macOS

Mojave were deleted, changing security settings, etc. Did full (well

99.99%) download twice only to have it produce the same message at the

very end. I am not the only one with this issue; support escalated to a

higher level and I have to get back on with them today.

If you downloaded it successfully—it would be sitting in your Applications folder

"Install macOS Mojave.app"

I had to stop last night, ran out of time but will get help from support today as suggested by @fyip and will report back here. Thanks.
