There has been a new major operating system release for your Mac. It’s called Yosemite (‘Yo-sem-an -ee’) or OSX 10.10. Go to the App store on your Mac. It’s free but allow 2-3 hours to download and update.
There is also an update being released on Monday 20 October for your iPhone and iPad. It’s iOS8.1. Make sure you are connected to a wireless network to download it.
A couple of great features when the 2 are combined is that you will be able to text everyone from your Mac and or iPhone / iPad and all will be kept up to date. Same with phone calls. If you iPhone is around you will be able to make and answer calls from your Mac.
