I have a Mid-2010 Macbook Pro CPU- 2.4GHz Intel Core 2 Duo RAM- 4 GB DDR3 GPU- NVIDIA GeForce 320M 256 MB Every time I open Steam, it ends up reducing the amount of free ram into the Megabytes. These are two instances that happened when Steam was essentially the only program open. I've already tried uninstalling and reinstalling Steam to see if that would help. Unfortunately this still happens. Is this a problem with Steam and its coding or is it a problem with my computer?
