rox_rahul@ymail.com Posted January 20, 2019 Share Posted January 20, 2019 I have my lenovo z570 with OSX ElCapitan installed. Everything works except wifi (because of the card, obviously). But I experience slowness in the system. I cant run facebook on safari, it hangs after scrolling for a while and then I have to force turn off the laptop using power button. My laptop has upgraded to 6GB RAM, 120 GB samsung 850 EVO ssd. Sometimes it hangs even after starting without starting any app. Please help.
