You can configure your Mac to either lock automatically as soon as it enters a sleep state, or you can specify that your Mac should wait for a certain period of time before triggering the lock function. However, it’s still a good idea to setup your Mac so it goes to sleep and then locks automatically after it’s been sat idle for a while, as this can be a useful fallback for those occasions when you do forget to lock your Mac. Ideally, you should get into the habit of manually locking your Mac whenever you’re leaving it for a significant period of time. In this article I’m going to be sharing various techniques that you can use to lock your Mac quickly and easily, so you can select the method (or methods) that work the best for you. There’s various ways that you can lock your Mac, ranging from using a keyboard shortcut, to configuring a hot corner or, if you’re lucky enough to own one of the new MacBook Pros, you can even add a Lock button to your Touchbar. Hopefully, the worst that’ll happen is some practical joker updates your Facebook status or changes your Desktop wallpaper, but in the worst case scenario someone could go snooping through your files, accessing sensitive data and maybe even modifying your Mac’s contents without your consent. If you’re in the bad habit of walking away from your Mac and leaving it unlocked, then you’re running the risk of other people accessing your Mac in your absence. Although your Mac will lock automatically whenever you close the lid, for increased security you should try and get into the habit of locking your Mac every time you step away from it.
