After the installation of the Portal 2 video game I found a small problem on the system. Actually yesterday, I done the Portal 2 video game installation on the Macbook pro operating system. The installation complete successfully and after that I locate the system icon. Then I see that the entire portal icon is being converted to the steam icon. I used the steam for the installation of the portal 2 game. Any type of help for solving this small problem will be appreciated.
