if ([NSWindow respondsToSelector:@selector(setAllowsAutomaticWindowTabbing:)]) {
// Disable automatic tabbing on 10.12+. MacVim already has its own
// tabbing interface, so we don't want multiple hierarchy of tabs mixing
// native and Vim tabs. MacVim also doesn't work well with native tabs
// right now since it doesn't respond well to the size change, and it
// doesn't show the native menu items (e.g. move tab to new window) in
// all the tabs.
//
// Note: MacVim cannot use macOS native tabs for Vim tabs because Vim
// assumes only one tab can be shown at a time, and it would be hard to
// handle native tab's "move tab to a new window" functionality.
