M-theory compactified on G
2-holonomy manifolds results in 4d
$$ \mathcal{N} $$
N
= 1 supersymmetric gauge theories coupled to gravity. In this paper we focus on the gauge sector of such compactifications by studying the Higgs bundle obtained from a partially twisted 7d super Yang-Mills theory on a supersymmetric three-cycle M
3. We derive the BPS equations and find the massless spectrum for both abelian and non-abelian gauge groups in 4d. The mathematical tool that allows us to determine the spectrum is Morse theory, and more generally Morse-Bott theory. The latter generalization allows us to make contact with twisted connected sum (TCS) G
2-manifolds, which form the largest class of examples of compact G
2-manifolds. M-theory on TCS G
2-manifolds is known to result in a non-chiral 4d spectrum. We determine the Higgs bundle for this class of G
2-manifolds and provide a prescription for how to engineer singular transitions to models that have chiral matter in 4d.
