what's up guys it's Lou from unbox therapy and I'm going to show you real quick how to do a restore a factory-fresh restore on your 2011 MacBook Air the first thing you got to do is shut down the system obviously pretty self-explanatory and the reason I'm showing you this video is because this one is a little different to do than previous models there are no restore discs and there's no restore USB so you kind of need to know what you're doing the first trick is the power plus option key trick you got to hold both of them down at the same time after you hit the power button you can see the machine booting up you can let go of power but keep holding option and once you've done that you'll see two options amazing the option key gives us options what a surprise you've get the Macintosh hard drive on the left and then you've got something called recovery HD on the right that's the important part you want to select it click enter and it'll boot into this special recovery partition that's hidden on the SSD very cool what you can do from here is a number of things you can either wipe your system out clean completely delete everything or you can restore from a time machine back up or you can access Disk Utility number of things so the first thing if you want to wipe it clean is to open up Disk Utility and erase your hard drive obviously that's very important so you want to select Macintosh HD that's where everything you've got is stored that will present you with a number of options across the top the one that's important for this particular scenario is the erase option that's how you're going to wipe it out of course there are two buttons down here and you select the race and then you've got to confirm it because after that it all happens very fast if you you don't want to do this by accident you know you get some stuff on there that you're trying to protect now you really want to make sure that you want to erase it from there you've got to reinstall an OS though the disk is clean at that point so you want to select reinstall OS and this is obviously an OS 10 Lion system now I sort of thought that maybe it stored the entire OS on that hidden partition but I was wrong in fact it's got to go and get the components from the Mac App Store so you spend a lot of time sort of retrieving those components from the web even more so than installing it so that's a bit of a headache but you want to select your Macintosh HD the same one that you wiped out as your install destination of Cour and then it'll go reach out to Apple's server and servers I'm sure they don't have one and start to grab those components necessary for the installation of Lion there's obviously some kind of authentication process making sure that they're going to give you the right set of components for your system after that's all completed you get a system reboot and then it begins to install this takes about half an hour so it's about 45 minutes for the download and then about half an hour for the install so not you got to set aside a little bit of time so you get a little check mark after that part has completed and an automatic reboot which will bring you back to factory fresh you will boot right back up as if you just pulled this thing out of the box so anyway guys the reason for this was just to illustrate the steps involved in in restoring your system of course and since it's unlike any of the Mac books before it I thought it would be you know worth doing a video about I also think you're probably going to see this kind of restore system in other Mac books and maybe the entire Apple line at some point so it's good to familiarize yourself with this particular process anyway guys if you enjoyed this content hopefully you can like and favorite this video as it does help me out a bunch and if you haven't checked out my new channel yet it is called the beast feat I'll put a link in front of your face as well as down in the description you might like what's going on over there so come pay us a visit subscribe if you like it otherwise I want to thank you for watching you guys make this content possible and until next time I will see you around a channel alright later guys you
