Reasons to install the display driver:
- No monitor attached to the Mac, "headless"
The virtual display driver is needed in the case you have a Mac without a monitor connected, "headless". For this case, you may need to install the display driver to have control of the Mac through Splashtop.
Note: From macOS 10.13.4 and newer, you do NOT need the display driver for headless.
