El Capitan’s Disk Utility is a handy tool for troubleshooting and repairing your hard drive (whether you’re noticing that your Mac has slowed considerably or you have problems opening files and applications). You can find it in the Utilities folder within the Applications folder. From Launchpad, click the Utilities folder and then click the Disk Utility icon.
In the left column of the Disk Utility window, you can see
- The physical hard drives in your system (the actual hardware)
- The volumes (the data stored on the hard drives)
Disk Utility got a facelift with the launch of OS X El Capitan. But this makeover didn’t go well for a handful of Mac users. Some of them find difficult to perform regular disk management activities on Apple hard disk drives including partitioning the disk, creating, resizing and deleting a partition. It will ask you to format the hard drive to confirm. Click on Done button when it’s done. Close the Disk utility windows and go back to the recovery mode. Now we are going to install Mac OS X El Capitan. Select Reinstall OS X in the Recovery Mode. Click Continue when the OS X installer comes up. My MacBook Air is running a 120GB SSD drive so I don’t want my hard drive full of excess things I don’t need. I just noticed after El Capitan that I lost a lot of space. I only had 10GB free. To run well a mac hard disk needs at least 20% free. Here’s how I freed up some more space. I ran Disc Inventory X to see where the excess space was. 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).

Because of this, I recommend creating your own bootable El Capitan (OS X 10.11) installer drive on an external hard drive or USB thumb drive. If you need to install El Capitan on multiple Macs.
- Any CD or DVD loaded on your Mac
- External USB or Thunderbolt hard drives
- USB flash drives
- Flash drives (like thumb drives) are external hardware devices that you can add to your Mac for additional storage room or as secure places to back up your data.
Here, you see one internal hard drive (the 1TB SATA entry, which is selected) and one USB external hard drive (the Toshiba entry). The hard drive has three volumes (Wolfgang, Ludwig, and Johann), and the USB drive has one volume (Time Machine).
Disk Utility also fixes incorrect file permissions automatically. Files with corrupt or incorrect permissions can
- Make your Mac lock up
- Make applications act goofy (or refuse to run)
- Cause strange behavior within a Finder window or System Preferences
Using Disk Utility to repair your hard drive carries a couple of caveats:
- You can’t repair the boot disk or the boot volume if OS X won’t run. This statement makes sense because Disk Utility is launched from your boot volume. (The boot volume is usually your Mac’s internal hard drive, where El Capitan is installed.) If OS X isn’t booting completely or is locking up, you can’t launch Disk Utility.
To repair your boot hard drive if OS X isn’t running, you need to boot your Mac from El Capitan’s Recovery HD volume. Hold down the Option key immediately after you hear the start up chord to display the Mac OS X boot menu, and choose the Recovery HD volume. When the Recovery window appears, run Disk Utility. Because you’ve booted the system from the Recovery HD volume, you can repair problems with your start-up hard drive.
Select your boot hard drive or volume in the sidebar at the left, and the First Aid button should be enabled.
- You can’t repair CDs and DVDs. Because CDs and DVDs are read-only media, they can’t be repaired (at least not by Disk Utility).

If your Mac is having trouble reading a CD or DVD, wipe the disc with a soft cloth to remove dust, oil, and fingerprints. If that technique fails, invest in a disc-cleaning contrivance of some sort. Look for a CD/DVD cleaning kit.
If OS X El Capitan is running fine, and you need to repair a disk or volume, follow these steps:
- Save all open documents, and quit all running applications.
- Click the Spotlight search icon on the Finder menu bar, type Disk Utility, and press Return. (From within Launchpad, click the Utilities folder and then click the Disk Utility icon.)
- In the list on the left side of the Disk Utility window, click the disk or volume that you want to check.
- Click the First Aid button and then click Run to confirm.
If Disk Utility does indeed find errors, they’ll be fixed automatically. Would you expect anything less from our favorite operating system?
What to Pay Attention to Before Installing OS-X-El Capitan to a New Panel and Dual Booting Yosemite?
- Enough hard disk space - The primary factor you must consider before installing OS-X-El Capitan to a new Partition on your Mac device is the hard disk space. In order to install the new Mac OS, you need a minimum hard disk space of about 40GB, and within this, you need a minimum of 20GB for the El Capitan. You must not allow your Mac OS X installation run on a low available disk space, otherwise the performance of your system will suffer.
- Back up your Mac machine - Do not recall creating a backup for the Mac device before installing OS-X-El Capitan on it. When you divide a Mac system and set up a new OS-operating system, you should consider some of the risks you may face, and one of such is permanent data loss. In order to avoid this loss, you must complete a backup for all your files.
- Make sure you have the OS-X-El Capitan installer - Regardless of whether the installer is running from the applications folder or downloaded directly from Apple store, the OS-X-El Capitan installer works perfectly well from within the bootable OS-X-El Capitan installer drive to ensure that you don’t have to re-download the OS-X-El Capitan software.
- Follow all system requirements for the download and installation - Make sure your Mac device is on the list of compatible devices for the installation of Mac OS/X/El Capitan include; iMac 2007 or maybe newer, 2008 MacBook Air or newer, 2009 MacBook Pro or newer, Mac Pro 2008 or newer, and 2009 Xserve or newer. For superior performance, it is expected that you have a minimum of 2GB RAM, and your Mac device must also have a faster SSD for enhanced performance of Mac OS-X-El Capitan.
Guide to Put in OS/X/El Capitan to a New Partition in Addition to Twin Boot Yosemite on Mac
There are quite a few steps involved in installation of Mac OS/X/El Capitan on a new partition and when you dual boot Yosemite on your Mac device, these are:
Step 1. Select Open the Disk Utility plus choose the hard drive for which you want to partition (this is located at the left side set of choices on the screen and it is also referred to as the Macintosh HD).
Step 2. Create Click on the “Partition” tab from the Macintosh HD screen, and click on the positive (+) button in order to create an entirely new partition. Give it a name such as “Mac OS/X/El Capitan” and resize it.
Step 3. Apply Simply click on the “Apply” button to create an original partition, and you need to confirm after a request has been sent – do you wish to partition the target volume? Simply confirm and let the divider complete its process before you opt out of the Disk Utility.
Step 4. Launch Simply launch the “Install OS/X/El Capitan” app and agree to the Terms of service (TOS), and you will see the drive selector showing up- simply click on the “Show All Disks” option.
Step 5. Install Simply select the OS-X-El Capitan (or whatever the name of the panel you created earlier on) and click on “Install”. Allow the Installation to complete and you will see the Mac rebooting automatically into your new OS/X/El Capitan when the whole process has been completed.
Step 6. Switch Now that your new OS-X-El Capitan is running on another partition, you can switch easily in-between two start-up drives on your Mac by rebooting your Mac while holding down the “Option” key. Holding downward the options key will definitely open the startup manager right before the OS X load on your Mac, and will give you the option of choosing between the version of the Mac OS you want to use or run. Rebooting and selecting between El Capitan and Yosemite is one of the best possible ways to switch, especially when you are still getting use to the new El Capitan.
