How to upgrade to OS X El Capitan

OS X El Capitan remains available for Mac computers that can't upgrade to macOS Mojave, High Sierra, or Sierra, or that need to upgrade to El Capitan first.
 

 
Check compatibility

You can upgrade to OS X El Capitan from OS X Snow Leopard or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8.8GB of available storage space.

MacBook introduced in late 2008 or later
 MacBook Air introduced in late 2008 or later
 MacBook Pro introduced in mid 2007 or later
 Mac mini introduced in early 2009 or later
 iMac introduced in mid 2007 or later
 Mac Pro introduced in early 2008 or later
 Xserve models introduced in early 2009


To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple () menu. If your Mac isn't compatible with OS X El Capitan, the installer will let you know.


   Make a backup

Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.


   Get connected

It takes time to download and install OS X, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.


   Download OS X El Capitan

For the strongest security and latest features, find out whether you can upgrade to macOS Mojave, the latest version of macOS.

If you still need OS X El Capitan, use this App Store link: Get El Capitan. To download it, your Mac must be using macOS High Sierra or earlier.


   Begin installation

After downloading, the installer opens automatically.
Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.
 
   
Allow installation to complete

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both OS X and related updates to your Mac firmware.



   Learn more

  • If you're using Leopard, upgrade to Snow Leopard to get the App Store. Then check for software updates by choosing Software Update from the Apple menu. After installing all Snow Leopard updates, you should have the App Store app and can use it to download OS X El Capitan. You can then use El Capitan to upgrade to a later macOS.
  • OS X El Capitan won't install on top of a later version of macOS, but you can erase your disk first or install on another disk.
  • You can use macOS Recovery to reinstall macOS.


How to reinstall macOS from macOS Recovery

Learn how to use macOS Recovery to reinstall the Mac operating system on your built-in drive or an external drive.

 Reinstall from macOS Recovery:

 macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu in the menu bar. This menu is also available in macOS Recovery.

1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following combinations on your keyboard. Command-R is generally recommended, especially if you never installed macOS Sierra 10.12.4 or later.

 Command (⌘)-R     Install the latest macOS that was installed on your Mac.
Option-⌘-R     Upgrade to the latest macOS compatible with your Mac.
 Shift-Option-⌘-R     Install the macOS that came with your Mac, or the closest version still available.
 
 Release the keys when you see the Apple logo, a spinning globe, or a prompt for a firmware password. When you see the Utilities window, you've started up from macOS Recovery.

 2. Decide whether to erase (format) your disk
If you need to erase your disk before installing macOS, select Disk Utility from the Utilities window, then click Continue. You probably don't need to erase, unless you're selling or giving away your Mac or have an issue that requires you to erase. Learn more about when and how to erase.

 3. Install macOS:     
After starting up from macOS Recovery, follow these steps to install macOS:

 
  • Choose Reinstall macOS (or Reinstall OS X) from the Utilities window.
  • Click Continue, then follow the onscreen instructions to choose your disk and begin installation.
     If the installer asks to unlock your disk, enter the password you use to log in to your Mac. If it doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk.
  • Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
If your Mac restarts to a setup assistant, but you're selling or giving it away, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

If you never installed macOS Sierra 10.12.4
If macOS Sierra 10.12.4 or later was never installed on your Mac, macOS Recovery works differently:

 
  • Command-R is still the recommended way to start up from macOS Recovery. This combination makes sure that the installation isn't associated with your Apple ID, which is important if you're selling or giving away your Mac.
  • Option-Command-R installs the macOS that came with your Mac, or the closest version still available.
  • Shift-Option-Command-R isn't available.
