If you aren’t already using Spotlight, oh, you’re missing out on one of the best features of the modern MacOS X operating system. Then type in ‘software update’, as shown: Simultaneously press Command + Space and the Spotlight window will pop up on your Mac screen. Still, a bit of paranoia is not unreasonable, so let me show you how to quick check for updates and force one to be applied if it’s available.
