Hi, this is gary with macmost . on today’s episode let me show you how to get your mac ready for resale or recycling. Before you do anything else you want to make sure you are completely done with the Mac. So you want to make sure all your data is off it. Get your new Mac up and running. Perhaps you’ve backed things up, archived things. You don’t need anything else on the hard drive. In addition you want to make sure you log out of a lot of different services. You want.
You make sure you go to itunes and use the deauthorize menu choice there to deauthorize iTunes. You want to make sure you go to iCloud and turn off iCloud including Find My Mac. You want to make sure that is off and any other thing you may think of. For instance I use Adobe Creative Cloud. I would want to make sure I was fully logged out of that so that I can again reinstall Abode apps on my new Mac. So I want to wipe this 2006 iMac, 20 inch iMac, and I’ve already got everything set.
On this. i’ve got icloud disabled, everything like that and i don’t have any data i need on here. I’m going to Restart and when I Restart I’m going to hold down the Command and R keys. That is going to restart it in recovery mode and bring up the recovery partition. So now in recovery mode with recovery partition I’ve booted into a completely separate part of the drive. The same as having an optical disk in there that you can boot to except.
That it is just a separate little part of the hard drive that you’ve probably haven’t even needed up until now. There are two things that I want to do. The first thing is that I want to run Disk Utility. Disk Utility, which you may recognize because you can bring it up and use it for other things when you are using your Mac normally. Select the drive here and you click Erase. Then you want to erase it. Format Mac OS Extended (Journaled). Give it a name like Macintosh HD, something.
Standard like that. But you want to select the Security Options here. Then you can select how much erasing you want to do. You want to move it up one notch to this setting that allows you to, it will write zeros over the entire drive. Not only destroy what is on the drive but actually override it completely. You have higher options here that will take a long time to do and you don’t really need.
Those for most macs. if you work in some sort of sensitive industry then you might want to use those but then if you do you probably have IT people handling this for you. You wouldn’t be doing this yourself. So do the first setting here. You can see it says will zero out data. Then you erase. That will take a little time to zero everything out. Then when it reboots into Recovery Partition you end up back here now with an empty hard drive with only disk recovery partition on.
It. You would do reinstall Mac OS X and it is going to hit you, most likely, with that it can’t connect to the network. It needs the network to be able to grab Mac OS X. It is not installing it from something it has locally. It is actually pulling it from Apple servers. So you want to go and turn on WiFi and select a network. You are going to have to enter in a password. Once it joins the network it will take just a few seconds, you can see.
Up there that it has joined, you can try again. you can see now it is ready to continue. So you can continue now installing. It is going to install the operating system that came with the Mac, in this case the one up from that since Lion is the first version that it can do an installation from Apple servers. So you may see Lion, Mountain Lion, Mavericks, or Yosemite here and it will install over the network. Then what you want to do is when you get to the point where it asks you to register, just.
Erase and Completely Reset Your Mac 1285
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.
