how do I download MacOS Mojave 10.14. 6

The Age of the computer will govern what Version of macOS it can upgrade to. Open About this Mac will provide those details

Mojave - Specifications Required Last macOS to still support 32 bit apps / extensions and Drivers

Catalina - Specification Required No Support for anything 32 bit

Big Sur - Specification Required No Support for anything 32 bit

Whatever upgrade is decided on - make a Time Machine Backup Before attempting.

Generally speaking, Apple wants people to upgrade as far as their Mac hardware will go. If you go to System Preferences/Software Update it will point you to download Catalina or Big Sur.

But, assuming you know what you want:

In Safari, go to https://apps.apple.com/us/app/macos-mojave/id1398502828?mt=12 

That will open the App Store page for Mojave.

Just going to the App Store and searching for "Mojave" won't do it.

Make sure you back up everything first onto an external Time Machine drive!

You know that the income tax deadline (for Federal and most states) has been extended to May 17th, right?

I have had to upgrade macOS to be with TurboTax twice before; once I had to use a friend's Mac because my old one couldn't be upgraded that far. Intuit for some reason doesn't like being backward-compatible.

My existing Mac won't go above Catalina, so once they require Big Sur, it's mandatory hardware upgrade time.

When I click there, I get a pop up that says "This is not available from the UK store." So I try logging in to the US store and get the same message but "from the US store"! Help. I need to upgrade from High Sierra to Mojave to run Panopto to record lectures I'm giving for my university, but can't upgrade to Catalina as my MS Office for Mac are all 32 bit.... And I need to make powerpoints for the lectures. ARGH!

YES!! That worked!! My browser default is Firefox as so many university apps and software won’t work in Safari. (Everything is optimised to Chrome, but I hate Chrome, so use Firefox.) THANK YOU!! I was on with Apple Support for quite a while and he couldn’t resolve, except to try Safe Mode, but that didn’t work either!

Go application folder and delete the already installed “ Install Mojave “ and empty trash. Re download Mojave and stop. Restart in Safe Mode, Shift key immediately at startup. It will load slowly - normal. The run the installer

Darn, it still doesn’t work. It takes me to the Mojave page, but then it says “This copy of the install macOS Mojave application is damaged, and it can’t be used to install macOS”!!!! Argh!
