I have added a new article to my own #HIG for Mac apps: Toolbar Guidelines.

This article goes over how to design, organize, and use built-in #NSToolbar & #NSToolbarItem objects and their features.

It also goes over system behaviors when toolbars are mixed with Sidebars, Inspectors, & multi-content layouts!

As a bonus, it also goes over bottom bars & accessory bars. Check it out and let me know what you think!

The following sections are general guidelines that describe fundamental Toolbar layout and design principles on the Mac. Following these guidelines will help you create functional and aesthetically pleasing toolbars that are easy for Mac users to understand and use.
