After yesterday’s wrap up of my fix for vibrant table views, I have discovered that NSSplitViewItem has 3 initializer variants since macOS 10.11:

  • init(contentListWithViewController: NSViewController)
  • init(sidebarWithViewController: NSViewController)
  • init(viewController: NSViewController)

The latter will not add vibrancy. Guess who, by accident, discovered his table view to be wrapped in a init(sidebarWithViewController:) call.

I’ll leave the other post up as reference for deactivating vibrancy and dealing with NSTableView text drawing intricacies.
