mac save dialog not showing up for TextEdit/Word/Powerpoint/Excel
Step1: Open a textEdit and add some text into that (fig1)





Step2: press cmd+s and the following window will popup(fig2)





Step3: enter filename and specify the location to save (fig3)





Step4: press save button at the bottom of the window
Step5: Now this text document is saved and the - Edited in the
title is disappeared(fig4)




from now onwards when you want to save some text or documents you can press cmd+s and for conformation you can check whether - Edited is there in the title or not. If - Edited is still there means the document or whatever it is not saved.
Hope this helps.
By the way, i am using Mavericks hopes its the same with OS X Sierra
