By including the effects of superstring thresholds, we reconsider minimal string unification together with the requirement of producing a supersymmetry-breaking gluino condensate in the hidden sector. This gives, for examples of phenomenologically-viable Z8' and other related orbifolds, the constraint that 0.1215 ≤ αs(MZ) ≤ 0.1270. In such models, a hidden photino can be a source of cosmological dark matter detectable by gravitational microlensing.
