Set up Apple Mac
Set up Apple Mac: If you buy a used device, you’ll need to set up Apple Mac. To do so, be near a fast (at least 10 Mb/s) and reliable Internet connection. An Ethernet cable connection to the router would be preferred as it’s faster and more reliable than Wi-Fi.
Hold the command option/alt and r keys down and press the power button until something appears, connect to the Internet if on Wifi. What you will see on the screen is a globe icon as Internet Recovery is downloaded from Apple’s (via Akamai’s) Servers. (It doesn’t work for some older machines which are capable of Internet Recovery. These old computers usually have a slot for a 10.6 OS X install disk or require a 10.6 boot USB key from Apple).
You will see several options. Select Disk Utility and the disk0 selected on the left then chose Erase. If a slider option appears, move the slider one spot to the right for a Zero erase. The Zero option maps off bad sectors on hard drives and also deletes any fragments of the previous owners data. However, if you are handling sensitive data, move the slider all the way to the right for the maximum. It may take a few hours for the Zero erase to complete the process. If it fails after a few hours like it’s stuck, it means that the hard drive is defective. In this case it needs to be replaced by Apple.
If no slider for secure erase appears, it means your machine has a SSD or a Fusion/flash hybrid and there is no secure erase option available for these. If you chose to erase the drive, it doesn’t erase it in reality, just reformat the disk. The old data can be thus overwritten when you set up Apple Mac.
Next select the Partition tab and that the drive has 1 Partition, click the box, Option: GUID and the format is OS X Extended Journaled and the name is MacintoshHD. If not, make it so. From the File menu select Quit Disk Utility and select the Install OS X option. Using your AppleID and password, install OS X and Quit the installer which should reboot the machine.
Now you will see a Welcome to Mac video animation. At this stage you can select a language and setup your machine. If you enter your personal information at this stage or at the registration screen, Apple will take that information and personalize the machine placing your real name all over the machine, including broadcasting it wirelessly (short range) via Bonjour. So at this stage you may wish to use an alias. If you later find out it hampers your use of Apple services such as iCloud/AppleID and so forth, you can create an additional user account and log into that with your real name. Anyway you are your own judge on what your personal security needs are, because.
Once the accounts are set up, you log into AppStore and upgrade OS X to the version that was on the machine previously. Internet Recovery installs the OS X version that came with the machine from the factory.
You install now all your additional software you think you need. Connect the external drive containing your files you backed up previously. Select the drive on the Desktop and from the Finder Menu or right click > Get Info and at the bottom unlock and Ignore Permissions on this volume (By ignoring permissions your allowing the files to be copied, but they are still not entirely assigned to your new account).
Once you have placed your files or imported then into the appropriate programs, you want to create a bootable backup of the system state using a powered external drive and a copy of Carbon Copy Cloner. This bootable clone is accessible by holding the option/alt key down while booting the machine. The object with a bootable clone is to keep it disconnected and only update it when you know you have a pristine OS X boot volume or before you do something major in software, like a OS X update, program install and so on. You can boot from the clone and make more clones on more external drives, but they will only boot to that machine, but you can use Apple’s Migration Assistant to a new machine or use MacDrive to a PC if you ever need too. Keep in mind that the first clone takes the longest, the updates to the clone go faster.
If TimeMachine pops up and asks to make the external drive a TM drive, deny it, as you can make one after the clone is completed. TimeMachine software is always running on a Mac, if you connect a blank external drive it’s going to pop up a window asking you if you want to make one. Make sure the drive is free of data you want to keep and let TimeMachine do it’s thing.
After the bootable clone is created you may need a more always on and backing up solution, especially if you are prone to deleting files by accident. To set up Apple Mac, newbies should be using TimeMachine exclusively. Experienced Mac users can use bootable clones instead or a combination of the two methods for more reliability to set up Apple Mac.
