Updating Mac OS on an older Mac Pro

My Mac Pro is still using OS High Sierra and I'm trying to update it to the latest version of Mac OS. It's not allowing me to download the update. Is there another way for me to update my OS?

You could get Mojave from here: https://support.apple.com/en-us/HT211683

also see if your Mac pro needs a firmware update before trying to do so… please note that Mojave has certain requirements and your Mac Pro needs to meet those requirements… you might also have to change your system date to before 1995 before trying to install Mojave…


hope this helps
