I, too, have gone through a nightmare with small size toolbar icons on MacOS Tahoe. Every attempt I've made to programmatically swap out toolbar sizes has failed for NSToolbarItem -- unless it has an NSButton (bevel style) as a custom view. Apple's Coding Assistant has taken me down multiple blind alleys. Can't I just have multiple toolbars, including a small size toolbar where I can switch to it by hiding the full-size toolbar?
