macOS Sierra minor update changes Library shortcut keys

Update: See this article for the cause of the shortcut key change. It's a bug, not a feature…I think.

Via Michael Tsai and Kirk McElhearn, today I learned that I've been giving bad advice to our users ever since macOS Sierra 10.12.3 shipped.

It used to be that holding Option in Finder and then clicking the Go menu would reveal an entry for the normally-hidden Library folder. In macOS 10.12.3, for reasons unknown, Apple has changed this: The only thing the Option key does now is change Go > Enclosing Folder into Go > Enclosing Folder in New Window. To see the Library folder entry, hold down the Shift key instead.

So that's the bad news: They changed an undocumented shortcut that many users have been told to use when troubleshooting. The good news is they added a better, easier, and faster way to get to the Library folder: Just press ⇧⌘L in Finder. This matches all the other shortcuts—⇧⌘O for Documents, ⇧⌘D for Desktop, etc. (Downloads is the odd one out, as it uses ⌘⌥L.)

Note: This may be a short-lived change, perhaps even a bug—it seems to be gone in the 10.12.4 beta release. Either that, or the 10.12.4 build is a bug, and it's supposed to be how it is now in 10.12.3. Hey Apple, I have some advice on how to fix this whole messy situation: Stop hiding the Library folder by default! (Note that you can unhide it by showing View Options (⌘J) on your home folder and checking Show Library Folder.)



Remap non-modifiable keyboard shortcuts in any app

Ever run into a program that has some pre-defined keyboard shortcuts you don't like? In most cases, they're associated with a menu item, which means you can use macOS' built-in keyboard shortcuts function to fix them. (In System Preferences > Keyboard > Shortcuts > App Shortcuts.)

But what if the shortcut isn't associated with any menu item? Such is the case in Excel 365, which replaced a couple easy-to-type shortcuts (⌃I and ⌃K for inserting and deleting rows and columns) with much harder to type versions: ⇧⌃= and ⌃-. If there's no corresponding entry in the app's menus, it seems impossible to remap the shortcuts—unless the app itself offers that feature, which Excel did in prior versions.

The good news is that it is possible to remap any keyboard shortcut in any app, as long as you're willing to add one more program to the mix: Some sort of macro app. My example uses Keyboard Maestro, but any app that can send a key sequence in response to another key sequence will do the trick.
