Hi, I have a 2009 white MacBook Core 2 Duo 13' model # A1181 (EMC 2330). It overheats unless I keep the battery out of it. Having to keep it plugged in all the time is a pain, so I thought I'd get a cooling pad. Does anyone have any advice on which pad to get. There are so many and I can't find any advice for such an old Mac. Thanks.
