Plug the USB drive. The drive should mount on its own. Open Disk Utility (Applications> Utilities> Disk Utility). The flash drive must be listed on the left side of the window. Click it. Click the Erase tab. Make sure that FAT is selected as the format and click the Delete button.

You can use Disk Utility (you found in utilities folder inside the Applications folder) to format the USB pen in the Mac file system HFS +.
