fine. Software installation and setup are automated on Windows PCs; Macs or Linux boxes will
also work, although they’re a little more effort
to set up. To save space and equipment, you can
dispense with a keyboard and mouse by using a
remote control program such as TightVNC (free,
tightvnc.com) to install the Magic Mirror software.
