Hello. I've had my Macbook not running games properly since 2011. I've started playing games since TF2 became F2P and it will lag in any game. It even lags in old games like Grand Theft Auto III. I upgraded my RAM back in 2012 and it really didn't even do anything to help the performance. My Macbook is the White Unibody. My specs is 2.26 GHz Intel Core 2 Duo for the Processor and I have 8 gigs of RAM. My graphics card is an NVIDIA Geforce 9400m. Also when my Macbooks fan gets louder and hotter the game won't lag but it will start lagging again. If you want an example of this lag then here is the video Can anyone tell me how to fix this? - YouTube. Also if you put up the volume you can hear the fan being loud. Help would be appreciated. Thank you if anyone helps me.
