Change delay for auto-hide on menu bar In 10.11 is there a way to change the delay for showing the menu bar when auto-hide is enabled? I know for the dock you could use terminal and defaults write com.apple.dock autohide-delay -int 0
I ran the following Terminal command defaults find Menu Bar and found this:

Found 1 keys in domain 'Apple Global Domain': {
    "_HIHideMenuBar" = 0;
}

The _HIHideMenuBarproperty can be either 0 for Disabled or 1 for Enabled. And that's the same setting found in System Preferences - General - Automatically hide and show the menu bar.

So I guess it isn't possible as of today.
