It is shown that 2$M_\\odot$ are obtained for repulsive $YY$ interaction and preferably for a small or a large slope $L$. An attractive $\\Sigma$ potential in nuclear matter will favor the appearance of strangeness in stars with a mass as small as $\\sim 1 M_\\odot$, if, however it is repulsive only stars with a mass $\\gtrsim 1.4 M_\\odot$ will contain strangeness.
