I have a TN2056 Installable Keyboard Layout that I’ve placed in ~/Library/Keyboard Layouts. It is the default keyboard layout, and is used by all apps.
But now with the new version of OmniGraffle that runs in the sandbox, I am unable to use it. It shows up in the input menu but nothing happens when I click it; I get the default US English instead. I’m guessing it’s a sandbox problem, but it does show up in ~/Library/Containers/com.omnigroup.OmniGraffle6/Data/Library/Keyboard Layouts.
How can I use a custom keyboard layout in OmniGraffle 6?
