I have been a long time user of Lightroom on Windows, but just purchased an iBookPro. For a certain presentation I want to project images full screen with an info overlay. This works well with windows,but with my Mac laptop in full screen hitting CMD+J does not bring up the Library View Options dialog as it does in Windows. Also, cycling through the views with the shortcut key I works with full screen in Windows but not with my iBookPro. I am using OS X Mavericks, Ver 10.9.5.
A workaround is to use loupe view with the sidebars collapsed and with the toolbar, top panel, etc collapsed and selecting a custom zoom to fill the screen as best as possible. The info overlay can then be shown.
