Height of the apple menubar

Question

I was just wondering how to get the height of the apple menubar, in pixels (the one always on top)

(My screen size is 1200 x 800) i was wondering what it would be excluding the menubar.

Answer 1

As per @Ross's answer:

NSApplication.sharedApplication().mainMenu?.menuBarHeight

Unfortunately, this will return nil before the app finishes launching (because the mainMenu will be nil). If you need this value earlier than that (and you don't want to guess it for the future OS releases), you can calculate it like so:

if let screen = NSScreen.mainScreen() {
    let menuBarHeight = screen.frame.height - screen.visibleFrame.height - screen.visibleFrame.origin.y - 1
}

This number will not be correct only if there is some extra screen furniture (like the Dock for example) pinned from the top, which seems extremely unlikely.

Update: To support multiple displays (primary and secondary):

let appleMenuBarHeight = screen.frame.height - screen.visibleFrame.height - (screen.visibleFrame.origin.y - screen.frame.origin.y) - 1

Quick and simple Swift 5 solution:

NSStatusBar.system.thickness
