MacOS – How to tell Finder to always show the Library folder on Mavericks

In Lion and Snow Leopard, the option/alt key makes a subtle change:

• ⌘+▲ reuses the existing finder window (preserving sort, view and size of the child folder).
• ⌥+⌘+▲ opens a new finder window with the saved settings for that parent folder (closing the child folder)

There is no system-tweak-able setting (for now) that will change the "Go" menu behaviour.

Basically, whether you have a shortcut defined to open Library or not, you'll have to hold "Option" to make Library visible in the menu.

Alternatives from the comments for quick access to Library (as a workaround to it appearing) are to

• add ~/Library to your Finder toolbar
• add ~/Library to your Finder sidebar
• define a Finder keyboard shortcut
• unhide the folder with chflags nohidden ~/Library
• automate typing ~/Library and use Go To… Command-Shift-G
• place the folder in the Dock or an alias to it on the Desktop (or elsewhere)
