Mojave Causing Issues

[Wicked1]

I need to go back to High Sierra, but what is the app I can load on an external drive and where can you get the installer for High Sierra?

I am having lots of application issues with the new software until I can figure them all out I need to go back, any help would be great thanks.

Here is a link that will open the App Store to download High Sierra installer App:

Use the installer App to make a bootable USB installer.

This doesn't work tells me the version of OS on my machine is newer, so will not allow me to download it and make a bootable USB key

It just worked for me. I'm running Mojave 10.14 and just used the link to download High Sierra.
Here is what I saw:



I clicked the Download button and the download started:



After the download I got this window & clicked "Quit":



The High Sierra installer app was left in the Applications folder:



The 5.23 GB "Install macOS High Sierra" app can be used to create a USB installer.
