You can simply restart with Shift-Option-⌘-R and reinstall the macOS version the hardware shipped with or the most compatible version.

I know but that is not possible in every situation. I for example had no recovery mode on a MBP so I needed to get the Apple software on it somehow.

The tool from dosdude can do a bit more. With it I managed to install High Sierra on a MBP from 2009 (which isn't compatible anymore but it runs flawlessly).

Before it had an HDD with Windows only and no access to recovery mode or diagnostic tools. Thanks to the "High Sierra Patcher" everything works now :)
