My FPS in WoW has gone down by about 30%, my temps are up across the board(GPU is at 63c, CPU at 49c, not doing anything on my imac but typing this) and Safari won't open as it doesn't like the last pass plug in. But without it opening I can't even disable the plugin. So no safari for now. Also itunes won't download the 11 app updates that I have. No error, just doesn't do anything. And having network connectivity issues. Some sites open, most don't.
