just installed the sapphire radeon rx580 to my mac pro mid 2012.
the current os is high sierra version 10.13.6
Installing the better GPU seemed to be the fix to be able to upgrade to mojave ?
when i try to install mojave it tells me i need 10.14
I guess i didn't do enough homework on this?
Is there a way to get my current os to 10.14?
so i can install mojave?
thanks
Mac Pro, macOS 10.13
No, it sounds like you have tried to install an update for macOS Mojave,
downloaded from the Apple Support Download site this requires you to
already be running an earlier version of macOS Mojave.
To install macOS Mojave from High Sierra you need to download and install the full installer app
which is available from the App Store.
Please use Safari to access the following links do not use Firefox
How to upgrade to macOS Mojave - Apple Support
Go to Section 4 and click on Get macOS Mojave
you will be redirected to the App Store Mojave download page
it should say Get or Download.
This downloads Install macOS Mojave.app to your Applications folder.
double-clicking the app will start the installation.
The app self deletes when you install Mojave so make a copy of it
and keep it in a safe place for any future needs.
Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading
and do not use any other devices that share the same internet connection.
If the App Store says ‘Open’ then it is detecting a previous download of the install app
go to the Applications folder locate Install macOS Mojave.app.
Move it to the Trash, empty the Trash.
Restart, click on the link again, the App Store should say ‘Get' or 'Download'.

thanks for the quick response Eau. i went to the link and it said OPEN instead of download.
it appeared to be doing something? and then computer shut off.
did i miss a step?
thanks again.
im not good a reading directions. ill give it another go.
The very last paragraph of my instructions tells you
what to do if the App Store says Open.
All is good. installing now.
Thank you for your help. Your a lifesaver!
