Mac users get new software updates and versions more frequently than the other operating systems. That's both the blessing and curse for the Mac users. The latest software makes your Mac device compatible with the new technological developments. Still, it also makes the existing OS obsolete. That's why most Mac users with old devices try to update their Mac to OS X El Capitan. However, you can't update your Mac to El Capitan 10.11 if your Mac runs on software later than Mac OS X 10.6 Snow Leopard.

Is OS X El Capitan Still Available for Your Mac?

OS X El Capitan (10.11) was launched on 25 September 2015, and it is an improved version of OS X Yosemite (10.10). Improved window management, quick and responsive interface, spotlight search, and enhanced graphics were the prerequisites of El Capitan OS. However, if you are planning to update your Mac to OS X El Capitan, your device must fulfill the following requirements.

Space Requirements

You can't install OS X El Capitan unless your Mac has a free space of 8.8 GB. However, that's the space you need to install El Capitan on your Mac. You might have to free more space to run your Mac more smoothly because low space slows down system performance.

Hardware Compatibility

Most of the Mac models can install and run OS X El Capitan, but in some devices, you can't use full features of this OS due to hardware limitations. For instance, you can't use AirDrop on your Mac if you don't have a WiFi network compatible with PAN. The followings are devices that are compatible with OS X El Capitan.

  • MacBook introduced in 2009 or later, plus MacBook (13-inch, Aluminum, Late 2008)
  • 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

RAM Compatibility

RAM is the temporary memory that supports the system to run apps and programs efficiently. Without enough RAM, trust me, you can't even run your native operating system smoothly. Similarly, you can't install El Capitan unless you have 2 GB RAM on your Mac.

Operating System Compatibility

Operating systems play a critical role in creating an operational environment for both the software and the hardware. If you have decided to update your Mac PC, you have to make sure that your device doesn't run the OS later than Mac OS X Snow Leopard 10. 6. 8.

After you are done with checking the compatibility of your Mac device, it's time to follow some pre rituals to prepare your device for Mac OS X El Capitan 10.11. These steps are mandatory for the successful installation of El Capitan OS into your Mac, and Apple also suggests them.

Get Your Mac Ready for El Capitan Update

Unprepared installation of a new operating system can result in disappointment. Remember that you are going to get a relatively new OS for your older Mac. To increase the hardware compatibility of your Mac, you must go through a checklist for successful installation of OS X El Capitan.

Space in your Mac: This includes freeing space both on RAM and Disk drive. 2 GB RAM and 8.8 GB of disk space are mandatory because the installer would not proceed without the fulfillment of these hardware requirements.

Minimum battery requirement: During the OS update, a computer consumes battery quicker than the regular operations. Your Mac needs to have at least 45% battery to pass through the El Capitan installation.

Active Internet Connection: You can't proceed with any OS installation without an active internet connection. Along with the installation package, your Mac would also need some side installations throughout the update. Without the support of these plugins and drivers, you would be back to square one. So, an active connection is a must.

Update Apps: Outdated apps can halt the process of updating your Mac. As soon as the installation of Mac OS X El Capitan completes, you face a software crisis. Most of your apps would stop working, leaving you with a headache. That's why don't forget to update your apps before starting the update.

Backup Your Data: There's a high chance that you would lose your data during Mac OS X EI Capitan update because the new OS makes changes in every nook and corner of your PC. To prevent the possible data loss, make a double back up—one in the Time Machine and other in the external storage device.

If you want to perform a typical OS upgrade, it’s easy. You download it through the App Store. Here, we’ll go through the steps of installing EL Capitan from Yosemite.

It’s about preparation

Before you install the upgrade, there’s a little bit of prep work you should do. Our article on how to get your Mac ready for OS X 10.11 El Capitan is what you should read before you proceed. It covers:

Install Os X Capitan

  • Compatible hardware and older versions of OS X

  • Encryption issues

How to download El Capitan

Apple provides the El Capitan upgrade through its App Store. The download is a bit over 6GB, so you may want to download it at a time when you have other things to do—how long the download takes depends on your Internet connection and the amount of activity at the App Store. Or you can use your Mac while you wait, but be ready to save your work and quit when the download is done.

To download El Capitan, launch the App Store app in your Applications folder (or go to Apple menu > App Store). You’ll probably find El Capitan right away, especially if go to the App Store soon after the official release. Apple will probably have a banner at the top promoting El Capitan, but if you don’t see one, you can probably find it in the Free section in the far right column (you might have to scroll down to see it). And you can always do a search on El Capitan.

When you get to the El Capitan page in the App Store, click on the Download button. You may have to enter your Apple ID name and password, and after you do, the installer will download.

Copy the installer

Instal El Capitan

When the download finishes, the installer automatically launches. Don’t click Continue in the installer just yet. What you may not know is that the installer is downloaded to your Applications folder and then deleted after the installation is done.

If you ever need the installer again, you can get it in the App Store. But I like to make a copy of the installer. I often have to perform OS installations, so I make a bootable flash drive that I can use; it’s a lot faster than waiting for the download.

To copy the installer, you need to hold down the Option key as you drag the Install OS X El Capitan app in your Applications folder to the copy destination. If you don’t hold down Option, you’ll create an alias, not a copy.

Install El Capitan

OK, now you can click that Continue button in the installer window. (If the installer isn’t running, go to your Applications folder and double click the Install OS X El Capitan app.) You’ll be asked to agree and then confirm that you agree to the license agreement.

The next screen will ask you to select the disk for the El Capitan installation. If you have one storage device with one partition, you’ll see it in the installer window. But if you have multiple storage devices and/or multiple partitions, you can select the one you want by clicking the Show All Disks button. Make your selection and click Install.

Install El Capitan App

To continue, you must enter your username and password. The install will prepare to install, restart your Mac, and perform the installation. The Mac may restart again during the installation process. The install will take several minutes, so you may want to go for a walk, call your mom, take a nap, or catch up on chores while the software does its thing.

When the installation is finished, the Mac will restart and you’ll need to log in with your username and password. You may be asked if you want to send diagnostic data to Apple and that you need to log in with your Apple ID, and then a setting up screen will appear and go away. Appcleaner mac app store. You’re done.

Want to do a clean install of El Capitan?

A clean installation is when you install the operating system on a blank storage device. You can do this by creating a bootable El Capitan installer, and then use it as the boot drive for your Mac. You run Disk Utility to erase your drive and then proceed with the El Capitan installation.

Once the installation is done, you use Migration Assistant to transfer your data from a Time Machine backup.

Instal

Why should you do a clean install? Maybe you partitioned your storage device and want to change the scheme. Or maybe you’ve installed and removed lots of apps over time and want to get right of any lingering software components—if this is the case, don’t restore your data from a Time Machine backup. Manually copy your files and reinstall your software.
