I seem to have all the system requirements but I'm always lagging. Processor 2.5 GHz Intel Core i5 Memory 4 GB 1600 MHz DDR3 Graphics Intel HD Graphics 4000 512 MB Software OS X 10.8.5 (12F45) I'm not good with all this technical stuff so I'm not sure what else to put on here. I also have a Windows 8 laptop and it works fine with no lag at all.
