  We perform the most attractive channel (MAC) analysis in the top mode
standard model with TeV-scale extra dimensions, where the standard model gauge
bosons and the third generation of quarks and leptons are put in D(=6,8,...)
dimensions. In order to make the scenario viable, only the attractive force of
the top condensate should exceed the critical coupling, while other channels
such as the bottom and tau condensates should not. It turns out that the top
condensate can be the MAC for D=8, whereas the tau condensation is favored for
D=6. On the basis of the renormalization group equations for the top Yukawa and
Higgs quartic couplings, we predict masses of the top quark and the Higgs boson
for D=8 as m_t=172-175 GeV and m_H=176-188 GeV, respectively.
