Photoshop Save as pdf not show option

On Windows you can do it like we did it years ago. When Save As could not save a flat file from a layered document that 22.4 has reverted to.. You merge all layer together use save as to save your jpeg then backup in history, For jpeg a very simple three step interactive action with a shortcut like F2.  The interactive Save As step let you choose the destination location for the jpeg.  Not a Big Deal. You can also use a Script like the Image Processor Pro Script cas save a flat finsge file fron a layered document.

I do not know if this will Work on a MAC Adobe seems to have made this change because Apple changed Mac Files system to add Copy not overwrite old Jpeg file.   Adobe want Photoshop to work the same on Windows and Mac.  That is not possibles the OS have different file systems and application interfaces.  Adobe can not control what Apple and Microsoft do so Adobe may change your work on Mac or Windows trying to make Photoshop operation  appear the be the sane on both PC an Mac,  Its very annoying and disruptive for Adobe Customer.
