hi guys, i wonder who is using a mac? my mac used to read my cardreader just fine (like when i plug it in, immediately it pops up on my desktop). but then one day it stopped popping up on my desktop. the light on the cardreader didnt even light up when i plugged it into the mac. so i thought my cardreader was spoilt, and bought a new one. the new one worked fine for 5 tries, and now when i plug it in my mac, the mac doesnt detect it at all (however, the light on the cardreader lights up). can anyone provide some help with this please?? (:
