How do I disable the Show Tab Bar menu option in Sierra apps?

I've got an app that uses a Toolbar in a NSWindow. I don't want users to be able to customize this toolbar for aesthetic reasons. In Sierra there's a new Menu option that gets inserted into "Menu > View" called Show Tab Bar. How do I disable this? Enabling it only seems to increase the tool bar's height as I don't have extra labels showing under the icons.

On 10.12, you need to now set the following when the window is created as Tab Bar is now available by default:

[NSWindow setAllowsAutomaticWindowTabbing: NO];

The answer is the same in Swift and SwiftUI

func applicationWillFinishLaunching(_ notification: Notification) {
    NSWindow.allowsAutomaticWindowTabbing = false
}

Note that the call is made on the class NSWindow not on an instance of NSWindow

Swift 5

In your NSWindowController:

self.window?.tabbingMode = .disallowed

Swift solution:

override func awakeFromNib() {
    super.awakeFromNib()
    if #available(OSX 10.12, *) {
        tabbingMode = .disallowed
    }
}

To disable tabbing on individual windows call setTabbingMode:

if([window respondsToSelector:@selector(setTabbingMode:)]) {
    // this particular window doesn't support tabbing in Sierra.
    [window setTabbingMode:NSWindowTabbingModeDisallowed];
}

You can also do this on IB, on the Window’s attributes inspector

If you don't want to compile against the latest frameworks, you can use the following code in your NSWindowsController sub classes:

Swift:

 override func awakeFromNib() {
     if NSAppKitVersionNumber > 1500 {
        self.window?.setValue(2, forKey: "tabbingMode")
     }
 }

Objective-C:

- (void)awakeFromNib {
    if (NSAppKitVersionNumber > 1500) {
        [self.window setValue:[NSNumber numberWithInt:2] forKey:@"tabbingMode"];
    }
}
