macOS 11 Big Sur introduces many user interface changes that update the appearance of applications and make them more iOS-like. It also adds support for familiar iOS features — such as SF Symbols and text styles.<\/p>\n

[…]<\/p>\n

By default, toolbars are taller, window titles can display inline with controls, and toolbar items no longer include a bezel.<\/p>\n<\/blockquote>\n

I’ve found that in order to get the new title bar and the preferences toolbar style, you have to build using Xcode 12. It’s not enough to set NSWindow.toolbarStyle<\/code>.<\/p>\n

Even when using the new SDK, setting NSControlSizeLarge<\/code> on the view doesn’t give you the new large icon style. To get that, you need to use NSToolbarItem.bordered<\/code>, which requires macOS 10.15, instead of creating the view yourself. So that means separate toolbar implementations if you want to support macOS 10.14 and earlier. Because I’m no longer creating the view myself, I had to switch from NSSegmentedControl<\/code> to NSToolbarItemGroup<\/code>, but unfortunately NSMenuToolbarItem<\/code> doesn’t work when inside of a group.<\/p>\n

My main Mac is still on macOS 10.14, so I’m using #if __MAC_OS_X_VERSION_MAX_ALLOWED < 101600<\/a><\/code> to make the same code compile with both Xcode 11 and Xcode 12.<\/p>\n\n
