Something that you may need to do from time to time is to completely clean off a mac. This may happen if you’re trying to resell it or pass it along to somebody else. You want to get all your stuff off there and give them a Mac that’s just like new. So the first thing you want to do when doing that is make sure you are signed out of everything. For instance, look in Messages, look in FaceTime, look in iTunes, look in the App Store. Look everywhere you can think of and sign out and delete accounts.
Go into system preferences, make sure you’ve turned off all your icloud services and you’ve removed your iCloud account. You can see I’ve done that here. Nothing there. Under internet accounts make sure you’ve removed all your internet accounts. You can be signed in for things like Twitter, Facebook, etc.
Make sure they’re all gone. Go into Mail and make sure they’re all gone. Clean everything off. If you’re using Cloud services like for Microsoft or Adobe make sure you are logged out of that. All those applications. Make sure everything’s good and you won’t have anything hanging around on this machine.
For instance, you don’t want to have the imessage system still thinking this machine is something that should be sending messages. You want to make sure you are signed out of everything. The only thing that you want to keep around is WiFi. You don’t want sign out of WiFi because to use the internet recovery function, which is how we are going to clean the Mac off, we are going to have to use the WiFi so we.
Can contact apple and not only load in utilities that will help us clean off this mac but then reinstall the system clean and fresh. So what we want to do now is enter internet recovery mode which will instead of loading the operating system from your drive will actually load the operating system or a simplified version of it from the internet, from Apple so it will allow us then to clean off the drive and reinstall the system.
To do that we are going to restart and when we restart as soon as we hit this button i’m going to hold down the keys Option, Command, and R. That will put us in the internet recovery mode. I’m holding down those keys here and in a second you will see it show that we’re doing internet recovery mode. That’s what we’re doing now.
It’s going to take awhile for it to load the operating system remotely so it’s a good time to get a cup of coffee, have a meal and come back when it’s ready. So once it’s done, and it took me about twenty minutes with a pretty fast internet connection for it to load this version of the operating system and present me with this screen. Once it’s done the next step that you want to do is you want to choose from Utilities here Disk Utility.
So i’m going to choose disk utility and continue. This will allow me to erase the drive. So I can see here, here’s my Macintosh hard drive. This other thing here, this OS 10 base system, that’s what it just downloaded. Basically downloaded a temporary version of the operating system for me to be able to do this while I’m not using the hard drive.
