Using Game Center on Mac is pretty easy. First you need to launch the Game Center application. You won’t find it in the Dock, but we will show you how to access it easily.
One way requires you to open Launchpad (by pressing F3 button on your keyboard, or by pinching with your thumb and three fingers in case you are using a trackpad), and click on the Game Center icon.
You can also access the Game Center by launching Spotlight (click on the magnifying glass on the top right of your screen or press Command + Space).
After the Spotlight pops up, type “Game Center” and click on it or press enter (return).
Note: If you plan on using Game Center often, we suggest that you move it to the Dock, by simply dragging the icon from the list of applications.
Once you launch Game Center, you will have to sign in with your Apple ID. In case you don’t have it, you can click on the “Create Apple ID” tab and create it. If you have multiple Apple IDs keep in mind that each account has its own associated friends, scores and achievements. In case you want to change accounts, you can do that by signing out of the current one, and signing in with the Apple ID that you want to use.
During the process of creating your account, you can choose to make your profile public or private. In case you make it public – your profile, along with your real name, will be visible to other users when providing you as a recommendation to other users; however, only your nickname will be used in leaderboards.
After you create a profile you can add a photo and status if you wish. This photo will be visible to your friends and strangers you are playing games with, as well as anybody else who chooses to view your profile (in case you created a public profile). A status resembles a Facebook status, and it is basically a short message displayed on your profile, that you are able to change anytime you want on the “Me” tab.
