Hi, I'm not sure what I did but I cannot seem to get system preferences to open?? AT alll!!!!!!! I've clicked on the apple then clicking on the option for system pref, no luck, I've tried clicking on the icon on the dock, no luck, I've pulled it up in spotlight, no luck!!! Please help...I somehow have it set that when I click on something, Safari opens up and I'd like to change that to Chrome opening up. Hold me by the hand assistance please!!!!
