There is a Photoshop forum and you should be posting PS-specific questions there. However, if the OpenType option is greyed out in the character flyout, that simply means the font you are using is not an OpenType font. To use OpenType fonts in PS, install them into your OS as per usual for fonts or else install them into the Adobe fonts folder (in Windows, it's usually c:\program files\common files\Adobe\fonts, but I have no idea where it is on a Mac). Adobe apps usually do come with fonts, but they install themselves only to the folder above (or to an app-specific folder), and it's up to you to make them available to other apps via the OS.
