Reinstall Mac Os X Erase Hard Drive
Reinatalling the os alone does not erase data. But I do still recommend taking a backup by booting into recovery and click Utilities in the upper menu bar and then select terminal then type csrutil disable then type reboot then when your Mac boots up and when you hear the chime hold CMD+S then wait until the plain text is done loading then type mount -uw / then grab a pen drive to plug in to.

Looking for a way to install and run OS X on an external hard drive? This can be useful for a couple of different reasons. Firstly, it allows you to run another copy of OS X without needing any additional Mac computer.
Also, since you can run a full copy of OS X on the external drive, it can be used for troubleshooting purposes on other Macs or it can be as a kind of virtual OS X. I’ve already written about how you can install OS X in VMware Fusion, but that takes up space on your Mac. Using an external drive, you can save space on your Mac, though it might be a bit slower if you are using USB 2.0.

In this article, I’ll walk you through the requirements and steps to install OS X onto an external hard drive.
Format External Hard Disk
The first thing you’re going to need to do is format the external hard drive properly. The file format has to be Mac OS X Journaled and you have to use the GUID partition map. To do this, open Disk Utility and connect the drive to your Mac.
Under External in the left hand menu, click on your external hard drive and then click on the Erase button. Make sure you backup any data before you erase the drive. When you click Erase, a dialog will pop up where you can configure some options.
Give your drive a name, choose OS X Extended (Journaled) for Format and GUID Partition Map for Scheme. It should only take a minute or two for the drive to be erased and reformatted. Now your drive is ready for OS X.
Install OS X
There are two ways you can install OS X on to your external hard disk: by reinstalling OS X from the OS X Utilities repair screen or by downloading OS X from the App Store and running the installer. I’ll show you both methods in case one isn’t working for you.
The easiest way is to download OS X from the App Store. Once you open the App Store, you’ll see a link on the right for the latest version of OS X (El Capitan as of this writing).
How To Reinstall Os X
Go ahead and click the Download button to start downloading the installer. Note that if you already have that version of OS X installed, you’ll see a popup message appear asking if you still want to continue or not. Just click Continue.
Once it has been downloaded, just double-click the installer, which will be located in the Applications folder.
Keep clicking past the license agreement, etc., until you get to the screen that asks you which disk to install OS X on. By default, it is set to MacBook.
Click on the Show All Disks button and you’ll see an icon for the different disks and partitions on the Mac. I named my external hard drive OS X and that shows up in the middle.
You can also tell it’s an external hard disk because it uses the icon with the orange hard drive. Click Continue and then follow the instructions to complete the installation. Note that your computer may restart during the install and you don’t have to do anything. OS X will automatically continue installing onto the external hard drive rather than booting up to your internal version of OS X.
At the end of this article, I’ll show you how to boot up to the external hard drive, so skip down if you ended up using the App Store method. Note that by default, the Mac will start booting up directly to the external hard drive until you change it.
The second method to install OS X is to restart the Mac and press and hold the COMMAND + R keys. This will load up OS X Recovery.
The OS X Utilities screen will appear and here you want to click on Reinstall OS X. Again, you’ll go through some basic screens, but when you get to the hard disk screen, click on Show All Disks again.
Using this method, you’ll have to login using your Apple ID and password so that the entire OS X installer can be downloaded off of Apple’s servers. Whichever method you choose, it will take anywhere from 15 to 30+ minutes to install OS X onto your external hard drive.
While OS X is installing, your computer will restart a couple of times. Note that when it finally boots into OS X, that is the version running off your external drive. To switch back and forth between the internal and external drive, you have to restart your computer and hold down the OPTION key.
When you do that, you should see at least four icons. In my case, I have five because I have Windows installed using Boot Camp. Anyway, the grey MacBook and Recovery 10.11.2 icons are for my internal OS X and the orange OS X and Recovery 10.11.3 are for the version installed on my external drive.
Use the arrow keys to select which drive to boot from and then simply press Enter. If you have a newer Mac and a USB drive that supports USB 3.0, everything should run fairly fast. Overall, it’s a fairly straight-forward process and took me less than an hour to get everything working. If you have any questions, feel free to comment. Enjoy! Logitech m570 update.
If OS X El Capitan came preinstalled on your new Mac, you’ll probably never need this article until you decide to sell it. At that time, it’s a good idea to erase the disk and install a fresh copy of OS X for the next owner.
If you’re thinking about reinstalling because something has gone wrong with your Mac, know that an OS X reinstallation should be your last resort. If nothing else fixes your Mac, reinstalling OS X could well be your final option before invasive surgery (that is, trundling your Mac to a repair shop). You don’t want to reinstall OS X if something easier can correct the problem. So if you have to do a reinstallation, realize that this is more or less your last hope (this side of the dreaded screwdriver, anyway).
In this article, you discover all you need to know to install or reinstall OS X, if you should have to.Reinstalling is a hassle because although you won’t lose the contents of your Home folder, applications you’ve installed, or the stuff in your Documents folder (unless something goes horribly wrong or you have to reformat your hard drive), you might lose the settings for some System Preferences, which means you’ll have to manually reconfigure those panes after you reinstall.
And you might have to reinstall drivers for third-party hardware such as mice, keyboards, printers, tablets, and the like. Finally, you might have to reregister or reinstall some of your software.
It’s not the end of the world, but it’s almost always inconvenient. That said, reinstalling OS X almost always corrects all but the most horrifying and malignant of problems. The process in El Capitan is (compared with root-canal work, income taxes, or previous versions of OS X) relatively painless.
How to install (or reinstall) OS X
In theory, you should have to install El Capitan only once, or never if your Mac came with El Capitan preinstalled. And in a perfect world, that would be the case. But you might find occasion to install, reinstall, or use it to upgrade, such as
If your Mac is currently running any version of OS X except El Capitan
If you have a catastrophic hard-drive crash that requires you to initialize (format) or replace your boot drive
If you buy an external hard drive and want it to be capable of being your Mac’s startup disk (that is, a bootable disk)
If you replace your internal hard drive with a larger, faster, or solid state drive
If any essential OS X files become damaged or corrupted or are deleted or renamed
If you sell or give away your Mac
The following instructions do triple duty: Of course they’re what you do to install OS X for the first time on a Mac or a freshly formatted hard or solid-state disk. But they’re also what you do if something really bad happens to the copy of OS X that you boot your Mac from, or if the version of OS X on your Mac is earlier than 10.10 El Capitan. In other words, these instructions describe the process for installing, reinstalling, or upgrading OS X El Capitan.
You must have Internet access to complete this procedure.
If you’ve never had El Capitan on this Mac, the first thing to do is visit the Mac App Store, download El Capitan (it’s free), and install it. Once you’ve done that, here’s how to install, reinstall, or upgrade to El Capitan, step by step:
Boot from your Recovery HD partition by restarting your Mac while holding down the Command+R keys.
The OS X Utilities window appears.
Select Reinstall OS X, and click Continue.
The OS X El Capitan splash screen appears.
Click Continue.
A sheet informing you that your computer’s eligibility needs to be verified by Apple appears.
Click Continue to begin the process of installing or reinstalling OS X.
If you’re not connected to the Internet, you’ll be asked to choose a Wi-Fi network from the AirPort menu in the top-right corner.
The El Capitan software license agreement screen appears.
Read the license agreement and click Agree.
A sheet drops down, asking whether you agree to the terms of the license agreement.
Click Agree again.
Yes, you did just click Agree; this time you’re being asked to confirm that you indeed clicked the Agree button. If you don’t click Agree, you can’t go any farther, so I advise you to click Agree now.
Choose the disk on which you want to reinstall OS X by clicking its icon once in the pane where you select a disk.
If only one suitable disk is available, you won’t have to choose; it will be selected for you automatically.
Click the Install button.
A sheet asks for your Apple ID and password.
Type your Apple ID and password in the appropriate fields, and click Sign In.
Your El Capitan installation (or reinstallation) begins. The operating system takes 30 to 60 minutes to install, so now might be a good time to take a coffee break. When the install is finished, your Mac restarts itself.
If you were reinstalling El Capitan on the hard disk that it was originally installed on, or upgrading from Mavericks, you’re done now. Your Mac will reboot, and in a few moments you can begin using your new, freshly installed (and ideally trouble-free) copy of OS X El Capitan.
If, on the other hand, you’re installing El Capitan on a hard disk for the first time, you still have one last step to complete. After your Mac reboots, the Setup Assistant window appears.

Getting set up with the Setup Assistant
Assuming that your installation process goes well and your Mac restarts itself, the next thing you should see (and hear) is a short, colorful movie that ends by transforming into the first Setup Assistant screen (Apple Assistants such as this are like wizards in Windows, only smarter), fetchingly named Welcome.
To tiptoe through the Setup Assistant, follow these steps:
Reinstall Mac Os X From Usb
When the Welcome screen appears, choose your country from the list by clicking it once, and then click the Continue button.
If your country doesn’t appear in the list, select the Show All check box, which causes a bunch of additional countries to appear.
After you click Continue, the Select Your Keyboard screen appears.
Choose a keyboard layout from the list by clicking it once, and then click Continue.
If you want to use a U.S. keyboard setup, click the U.S. listing. If you prefer a different country’s keyboard layout, select the Show All check box; a bunch of additional countries’ keyboards (as well as a pair of Dvorak keyboard layouts) appear in the list. Choose the one you prefer by clicking it — and then click Continue.
The Select Your Wi-Fi Network screen appears.
Click the name of the wireless network you use to connect to the Internet, type its password, and then click Continue.
If you don’t see the network you want to use, click Rescan.
If you don’t use a wireless network, click Other Network Setup, and then choose one of the available options, or choose My Computer Does Not Connect to the Internet. Click Continue.
The Migration Assistant (also known as the Transfer Information to This Mac) screen appears.
Do one of the following:
Choose to transfer data, and then click Continue.
If this is a brand-new Mac or you’re installing OS X El Capitan on a Mac and have another Mac or Time Machine backup disk nearby, you can transfer all of your important files and settings by following the onscreen instructions and connecting the new and old Macs via FireWire or Ethernet cable.

Transferring data can take hours — that’s the bad news.
The good news is that once the data transfer finishes, you’re finished, too. In other words, you can ignore the steps that follow (which are only for brand new installations with no data to transfer).
Goodbye and good luck.
Choose not to transfer data, and then click Continue.
The Enable Location Services screen appears. Location Services allows apps such as Maps and services such as Spotlight Suggestions to gather and use data including your approximate location.
Select (or don’t select) the Enable Location Services on this Mac check box, and then click Continue.

This first account that you create will automatically have administrator privileges for this Mac. You can’t easily delete or change the name you choose for this account, so think it through.
You can’t click the Continue button until you’ve filled in the first two fields. Because a password is optional, you can choose to leave both password fields blank if you like. If you do, your Mac warns you that without a password, your Mac won’t be secure. If that’s okay, click OK. If you change your mind and want to have a password, click Cancel.
If you want a different picture, click the little picture to the right of your name (labeled “edit”) and do one of the following:
To take a picture of yourself with your Mac’s built-in camera, click the Take Photo Snapshot button. Then click Continue.
When the picture appears, you can change its size by using the slider control directly below the image and move it around in the frame by clicking your face and dragging. If you’re not happy with this snapshot, click Retake a Video Snapshot.
To select a picture from the Picture library, click the picture you want to represent you — the butterfly, dog, parrot, flower, or whatever — and then click Continue.
Click Continue to exit the Create a Computer Account screen. If you didn’t provide an Apple ID, skip to Step 13.
If you provided your Apple ID in Step 6, the Set Up iCloud Keychain screen appears.
Do one of the following:
Click Set Up iCloud Keychain. When the screen requesting your passcode appears, type your four-digit passcode, and click Continue.
If you’ve forgotten your passcode or don’t have one, click Forgot Code to Reset iCloud Keychain.
A verification code is sent to your iPhone or other Apple device.
Click Set Up Later.
