In a random conversation with a friend, I asked them how often they shut off their Mac, rather than putting it to sleep. And I was quite shocked at his response about how he didn’t remember the last time he shut off his Mac. I did some asking around and it seemed like everyone just put their Mac to sleep, almost never really shutting it down. Some even said that the only way their Mac shut down was when they ran out of battery! Well, that doesn’t even count as a shut down but it is quite shocking to know how people don’t realize the benefits a simple shut down can bring to your Mac.
The thing is, all operating systems receives updates. In fact, your Mac is by default configured to automatically receive these updates, when you have a Wi-Fi connection. The update files are downloaded in the background, when your Mac is relatively idle. But, an update is never automatically applied or implemented unless your Mac restarts itself at least once.
A mac usually restarts itself only when you restart it manually or when you shut it down and turn it back on. If not for shutting it down, you must at least try to restart your Mac once in a while. If you restart your Mac and you see it say “Your Mac is updating”, you are in for very good news.
With an update, especially the bigger ones, you can expect your Mac to work faster, in a more secure manner and be less susceptible to threats like spam, adware and viruses.
So, there are a couple of things to do. First, go to Apple settings and ensure that OS X updates are automatically applied and used. Second, shut down your mac once in a while and then restart it or just use the restart option if you don’t want to shut it down. Please understand that putting your Mac to sleep or hibernate is just not the same as a shut down or restart!
