Hi all, I have a 2009 macbook pro on mountain lion with a reasonably newly added crucial 960 in it (early November?). I've noticed recently that it is becoming very sluggish, if not unresponsive, when I choose to restart/shutdown. Sometimes it has needed up to 10 attempts at clicking shutdown for it to actually respond. I've left it a few minutes as well to see if it is just slow, but even with no apps running it isn't responding. Does anyone know what might be happening? As a side Q that might tie into this, the usb stick I use is getting sluggish as well, and its only using 8 out of its 64gb size... Thanks very much!
