What if you have two switches and you set both to the maximum priority? It
then selects the root based on MAC addresses. The highest priority doesn't
necessarily eliminate the possibility of the switch becoming the root
bridge.
Someone please correct me if I'm wrong.

John,
The root bridge is always lower than the highest priority setting.
By using 65535, the highest number possible, your example ensures that the
switch will never become root bridge.
To set another switch to be root bridge, enter
set spantree root <VLAN>. The bridge priority will be set to 8192 or 1 less
than the current root priority, whichever is less.
show spantree provides info about the designated root priority.
Hope this helps .....
