How to get old versions of macOS
If your Mac isn't compatible with the latest macOS, you might still be able to upgrade to an earlier macOS,
such as macOS Catalina, Mojave, High Sierra, Sierra, or El Capitan.

Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone,
and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices
that you're using with your Mac.

Quote:
Safe mode prevents your Mac from loading certain software when it starts up,
including login items, system extensions not required by macOS, and fonts not installed by macOS.
It also does a basic check of your startup disk, similar to using First Aid in Disk Utility.
And it deletes some system caches, including font caches and the kernel cache,
which will be created again automatically as needed.
