So my mac was having a couple of freezes and kept asking me to update. I thought this might be a good move since I hadn't done so in forever and have a 2012 macbook air. But now... I have problems with everything. Chrome freezes all the time. Mail won't connect. Vuze is glitchy. Any feedback or suggestions on this? I can't imagine that all of this would happen just because of the new OS. Thanks.
