I have an imac late 2013 model and can't install Office 2019 as it requires OS 10.14 or later and it has OS X on it at the moment. It looks as though the official links for Mojava and Catalina are dead, so how can I upgrade?

Thanks, where is the zip, can't see it on that page.
 
You'll have to check whether your iMac hardware is compatible with the OS you're choosing to install.

Yes it says Mojave is supported on this, it's a late 2013 imac. I guess if I do a Time Machine back up first I have nothing to lose if I upgrade and find it doesn't work?

Correct, you'll be able to roll back. But have the installer for the OS you are on ready. I can't remember if TM requires it or not but it's always best to have just in case.

Sorry, what do you mean by have the installer for the OS I'm on ready? I've not really got much experience with Macs.
 
Just tried it and it says No such file or directory: u'/System/Library/PrivateFrameworks/Seeding.framework/Versions/Current/Resources/SeedCatalogs.plist'
Could not find a default catalog url for this OS version
 
Should be, in fact as part of the new install you'll be asked if you want to transfer stuff using migration assistant and I believe it can take it from Time Machine.

I'd probably plug in an external drive first and take a full SuperDuper! or Carbon Copy Cloner backup as well, just to be 100% sure.
 
I think I've been overthinking things somewhat, I don't know why, maybe it's because I was trying to install Office 2019 on OS X and it obviously isn't supported for that OS, so I was thinking the Mac isn't supported natively with Mojave or something, duh.

I've just realised all I have to do is use the Mojave patcher tool from dosdude1 to download a copy of the Mojave installer from Apple's servers and install that over OS X which is what I'm doing at the moment, hopefully it all goes smoothly.

What I don't understand is why is Mojave still on the Apple servers when it isn't available to install from the App Store.
