LT and mac Capitain

Does LT work for macCapitain as a standalone app? I need desperately a spell checker for GREEK (this is my language and i write professionally), because the app offered by the official aplle representators in Greece (isquare) does not work correctly with Capitain (I cannot go back to Yosemite, its extremely complicated). I can write in Greek but i cannot use the spell checking. If LT does not work for Capitain, do y know any alyernatives that i could use with dictionary in Greek for spell checking? Thanks in advance
