It's been a long time since I used classic Mac OS seriously, but I don't think Mac apps really even used toolbars for actions like save, undo, paste, etc. Usually toolbars were for selecting tools (e.g. pencil, eraser, etc in paint) or tuning settings (e.g. font and color), with actions stowed away in menus and lacking iconographic representation. Thinking about it further, this is true of OS X too. Even though it made toolbars more ubiquitous, it was still unusual for "standard" actions to be placed there. I would think that a longtime Mac user probably associates "save" with the key shortcut ⌘-S more strongly than any kind of icon.
