Well the same update (Lion?) ruined saving overall. Apple has insisted that apps should never have a "save as." You can hold opt to do it anyway, but it silently overwrites the original too. Wtf bro.

You could make the case that the user could just do a different flow of duplicating the file first, but this is entirely different from how both Mac and Windows have worked for decades, and even the Mac apps by third parties don't do it this way.

The example of Pages from the article has actually since been changed to do the same thing.

Red "Delete" on the far left, then on the far right a gray/neutral "Cancel" button, and an orange (the app's primary color) "Save"
