mac save dialog not showing up for TextEdit/Word/Powerpoint/Excel

I'm facing the weirdest issue and have spent hours googling a solution but returned empty-handed. I have a Mac early 2015 laptop with OS X Sierra(10.12.5) installed on it. Whenever I try to save a word/ppt/xls/txt file with Word/Powerpoint/Excel/TextEdit, the dialog box doesn't show up. There's no confirmation of whether it's been saved or not and I have lost hours of work because of this issue. Has anyone here faced this issue before?

Thanks

Solution 1:

• 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
