MacOS – Change delay for auto-hide on menu bar

Found a possible answer over on superuser.com:

#!/bin/sh

# Removes the Wifi menu from the menubar.
# This setting is set on a per-user basis, so needs to be run as the user
# Will require a logout. A 'kill SystemUIServer' might work?

OIFS="$IFS"

menutemp=$(defaults read com.apple.systemuiserver menuExtras)
menutemp2=$(echo $menutemp | sed 's/( //')
menutemp3=$(echo $menutemp2 | sed 's/ )//')

IFS=','
read -a menuitems <<< "$menutemp3"
IFS="$OIFS"

for (( i = 0 ; i < ${#menuitems[@]} ; i++ ))
do
    if [ "${menuitems[$i]}" = '"/System/Library/CoreServices/Menu Extras/AirPort.menu"' ]
    then
        /usr/libexec/PlistBuddy -c "Delete :menuExtras:$i" ~/Library/Preferences/com.apple.systemuiserver.plist
    fi
done

Will test and update.

So it seems someone found a working solution, at last.

First,

• close your VMs
• Quit VirtualBox

then as root (or sudo ...)

• copy the file somewhere as backup, then edit (eg vi) /Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents/Info.plist
• and add the line shown in the middle

the line <key>LSUIElement</key> <string>1</string> to be inserted between LSCanProvideIMVideoDataSource and NSHighResolutionCapable

<key>LSCanProvideIMVideoDataSource</key>    <true/>
<key>LSUIElement</key> <string>1</string>
<key>NSHighResolutionCapable</key>          <true/>

save, then start VirtualBox again (I didn't have to log out/reboot).

The VM will not show anymore among the opened apps icons, but you can double click the VM in the VirtualBox to switch to it.
