Abstract
We analyze the;primordial protogalactic gas to investigate the role of thermal instabilities in the formation of condensations that could co ntribute to the MACHO mass function. We find that the previrialized pr otogalaxy could have undergone a thermally unstable regime, which defi nes a peak in mass condensations starting around 0.1 M. after being re processed by the environment that may be identified as giving origin t o the MACHOs. Effects of magnetic fields on this instability-driven MA CHOs scenario are also addressed.
