I know this question has been asked many times but it seems no better solution for it.

Changing the allowsUserCustomization property doesn't help. It seems there is no API to customize the items in toolbar's context menu.

Finder app has no "Use Small Size" while Notes app has only "Customize Toolbar.."

I would like to know if there is any way to subclass or extend or do whatever to the NSToolbar to achieve the purpose?

Updated 1:

According to @Khundragpan and this post, problem 1 can be solved by:

    if let contextMenu = window?.contentView?.superview?.menu {
        for item in contextMenu.items {
            if item.title != "Customize Toolbar…" {
                contextMenu.removeItem(item)
            }
        }
    }

But I don't think it's the best way.

Update 2:

Another way to solve problem 1 (thanks to @1024jp to point out this file):

    if let contextMenu = window?.contentView?.superview?.menu {
        contextMenu.items.forEach({ (item) in
            if let action = item.action,
                NSStringFromSelector(action) != "runToolbarCustomizationPalette:" {
                contextMenu.removeItem(item)
            }
        })
    }

Update 3:

A ton of thanks to @1024jp for helping me. I'm able to remove those things with a few tips and tricks from him. Check the answer below.

    you can get to toolbar menu via `let toolBarMenu = window?.contentView?.superview?.menu`. Now remove the menu items you don't want. – Khundragpan Sep 21 '16 at 18:06
  • @Khundragpan Thanks! But this doesn't solve 2nd (referring to the image) problem. And I don't think it's the proper way to deal with these. – João Oliveira Sep 21 '16 at 22:00

    I think it's better to filter menuItems not by item's `title` but by item's `action` for localization. FYI, I do the similar thing in my app: https://github.com/coteditor/CotEditor/blob/3.0.0-beta.2/CotEditor/Sources/DocumentToolbar.swift#L50-L78 – 1024jp Sep 22 '16 at 10:59
  • @1024jp Thanks! I'll check it. :) – João Oliveira Sep 22 '16 at 15:20
  • @1024jp Your code works great. Thanks a lot! But one thing is that the sheet is displayed before you remove the toggle button. Is there any way to implement it before the sheet displays on the screen? – João Oliveira Sep 22 '16 at 15:36

    @JoãoOliveira Aha ok, then, it's more beautiful to remove the button in `window(:willPositionSheet:using:)`, one of the NSWindowDelegate's methods. In this way, user don't need to see the button to be removed. – 1024jp Sep 22 '16 at 16:41

    I've also improved my code to remove the button before showing the sheet. https://github.com/coteditor/CotEditor/blob/0a929af194b6eff9197aaeecc661c607c8493488/CotEditor/Sources/DocumentToolbar.swift – 1024jp Sep 22 '16 at 16:59
  • @1024jp You're Genius! It does work perfectly! Thank you very much! `window(_:willPositionSheet:using:)` is the method I was looking for! – João Oliveira Sep 22 '16 at 17:57
  • @1024jp **May you please help me with [this question](http://stackoverflow.com/questions/39625942/nstoolbarflexiblespaceitem-is-constraint-to-nssplitviewitem-in-swift) also?** I don't know how to resize `NSToolbarFlexibleSpaceItem` as Apple apps do such as Notes, Mail, and Finder. – João Oliveira Sep 22 '16 at 19:18
  • @JoãoOliveira Glad to hear you succeed. Sorry, but I've never made such a type of toolbar item before and no idea. – 1024jp Sep 25 '16 at 10:49

    @1024jp I understand. Thank you very much! – João Oliveira Sep 26 '16 at 17:30

After 3 days, I finally did it. Here is the result.

You can implement and make your own class, but here I just want to keep everything in a file.

This is the WindowController.swift file. You can set the custom class of your window controller and run. Again thanks to @1024jp for the tips.

class WindowController: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()

        guard let window = window else { return }

        window.delegate = self

        window.toolbar = NSToolbar(identifier: "RestrictedToolbar")
        window.toolbar?.allowsUserCustomization = true
        window.toolbar?.displayMode = .iconOnly
        window.toolbar?.delegate = self

        keepOnlyCustomizableMenu()
    }

    // PROBLEM 1: Solution
