>My main computer is a Mac and I very much wish its "Finder" had navigation tools as nice as the "breadcrumb bar" you are describing in Windows.
It's not completely the same as on Windows, but:
- Shift-Apple-G lets you enter a directory path to open (including bash-like completion with tab).
- Option-Apple-P shows/hides the "path bar" at the lower edge of a window where the hierarchy of the current folder is displayed (including a spartan context menu).
On Windows I mainly use the explorer address bar to go to those hidden folders like ProgramData.
