On October 3rd Apple began to upload Sierra hardware on the computer of ‘randomly’ selected users who are using OS X El Capitan version 10.11.5 or later. It’s not a total sneak attack, you have to have enough space on your hard drive and already have automatic updates enabled on your computer. So if you are low on drive space or have disabled automatic updates, you are safe! But don’t fear the update, it has some cool features!

Do you use Siri regularly to send voice messages or order food from the local pizza shop? Sierra has Siri for desktop, so don’t worry if your phone is out of reach. The universal clipboard will allow you to jump from compatible devices to work on that sappy message you’ve been drafting for two weeks.
We typically recommend waiting for a couple of updates before installing a new OS and Apple isn’t forcing you to download so just turn off automatic updates until it gets to 10.12.2 and all of the kinks have been worked out. If you’re not sure if you have automatic updates enabled just go to System Preferences, click on App Store, and uncheck ‘Download newly available updates in the background’. Once it gets to version 10.12.2 or so you’re good to go!
