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 there is any file missing after the El Capitan update, check how to recover files after OS X update.
Begin Update Process
Your device is ready to embrace Mac OS X El Capitan 10.11 after going through the steps mentioned earlier. Now it's time for some real action.
Step 1Visit the official Mac App Store and search for Mac OS X El Capitan. Your search result would Stake you to the El Capitan page. You can also download El Capitan without the App Store by the following links.
Step 2From the official El Capitan page, you can download your required version.
Step 3Once the download is done, the El Capitan installer will pop up on your screen.
Step 4Press the 'Continue' button and wait for the installation to begin. You can proceed with the installation by following the instructions of the installer.
Step 5The installation process does not take a long time. Once the installation is done, you can restore your data from Time Machine or external drive.
Recover Lost Files After OS X El Capitan Update
Do you remember those pre-installation steps? Those steps were taken to minimize the chances of data loss during the Mac OS X El Capitan installation. Despite these precautions, you are still at the risk of unprecedented data loss. You can lose data due to the following reasons.
Data loss due to corrupted files: If your Mac contains corrupted files, you will lose your data. During installation, the new OS tries to fix or delete corrupted files. These overwritten or deleted files would not appear after installation.
Nature of Mac OS X El Capitan's update: You will replace your older OS with a new version that is not tailor-made for your Mac. That's a significant shift in the environment of your Mac. Such kinds of major updates come with uncertainty, and you can't predict whether you are going to lose your data or not.
Hardware specifications: 2 GB RAM and 8.8 GB disk space is a standard requirement for El Capitan's update. But it takes a lot more from a Mac device to adapt to a newly enforced environment. A slight incompatibility can make you lose your data without any notice.
Lost Your Data After Mac OS X El Capitan: What's Next?

Warning: Please follow these instructions at your own risk. I am not responsible for any damage or information loss that could result from following this guide. Also, note that installing OS X on PC is illegal. Please buy a real Mac if you're satisfied with your Hackintosh. This guide is for evaluation purposes only.
Requirements
- An Intel-based PC with UEFI bios
- A USB flash drive with at least 16GB capacity
- A dedicated hard drive (SSD highly recommended)
- A computer running OS X (10.9 or later) for preparing the installation USB flash drive
I chose to avoid the UniBeast installer (by Tonymacx86) because of its commercialized nature, as described here. Here is a vanilla guide to installing El Capitan on your PC!
Preparing the USB Installation Drive
First things first. We need to prepare a USB thumb drive that will contain the installation files as well as the bootloader and custom kexts for our specific Hackintosh build.
Download El Capitan from the Mac App Store
Head over to your existing OS X environment running 10.9 or later and open the Mac App Store.
Search for 'El Capitan' and click Download. The download is completely free if you're running OS X 10.9+.
Wait for the download to finish (this could take some time).
Format the USB Drive
Open Disk Utility in Applications/Utilities and locate your USB device. Make sure you've backed up anything important on that drive as it will be erased forever.
Select it, and then on the right, click the partition tab.
- Click Curent Layout and change it to 1 Partition.
- Set the Name to USB.
- Set the Format to Mac OS Extended (Journaled).
- Click Options and select GUID Partition Table.
Click Apply to format the drive.
Copy the Installation Files to the USB Drive
Now that we've downloaded the installation files from the Mac App Store and formatted our USB drive, let's copy the installation files to it.
Run the following command in the Terminal (Applications/Utilities):
The command will run a script inside the Install OS X El Capitan application that will copy the installation files to the USB drive.
This process takes about 15 minutes. Go out for a quick run, or a hamburger, or both. When you come back, it should have finished.
Installing a Bootloader
If you tried to boot from the USB drive as is after the previous step on a PC, it wouldn't work. We need a bootloader that makes it possible to boot OS X on x86 and x86_64 PCs.
There are 3 popular bootloaders to choose from.
- Clover
- Chameleon
- Chimera
I went with Clover as it seems to be the most popular choice among other El Capitan installers, mostly for the following reasons:
Clover is an open-source EFI-based bootloader created on Apr 4, 2011. It has a totally different approach from Chameleon and Chimera. It can emulate the EFI portion present on real Macs and boot the OS from there instead of using the regular legacy BIOS approach used by Chameleon and Chimera. For many, Clover is considered the next-gen bootloader and soon it will become the only choice since BIOS in being replaced by UEFI in every new motherboard. One big feature of Clover is that iMessage, iCloud, the Mac App Store works along with Find My Mac, Back To My Mac and FileVault since Clover can use the EFI partition. (Read more)
Install Clover on Your USB Drive
Installing Clover on your USB drive is relatively easy. It involves running an installation wizard and selecting some options.
Download the latest Clover installer from here.
- Run the installer.
- Click Continue twice.
- Click Change Install Location and set it to your formatted USB drive.
- Click Customize and check the following options:
- [x] Install for UEFI booting only
- [x] Install Clover in the ESP
- [ ] Drivers64UEFI
- [x] OsxAptioFixDrv-64 - fixes memory map created by AMI Aptio EFI. Booting OS X is impossible otherwise.
- Click Install and wait for the installation to finish. It shouldn't take more than a minute.
Copy Essential Kexts to the USB Drive
Next, we'll need to copy some kexts (kernal extensions, similar to drivers on Windows) to the USB drive.
- FakeSMC.kext - open source SMC device driver/emulator developed by netkas. Tricks OS X into thinking it's installed on Apple hardware. Absolutely required for Hackintosh installation.
- NullCPUPowerManagement.kext - disables AppleIntelCPUPowerManagement.kext which may cause kernel panics when you try to boot from the USB drive. It's optional, copy it only if you get an AppleIntelCPUPowerManagement-related kernel panic.
- ApplePS2Controller.kext and AppleACPIPS2Nub.kext - adds support for PS2 devices (such as PS2 keyboard/mouse). They're optional, copy them only if you still use PS2 devices.
Download these files from here and copy them to the EFI mounted volume at /EFI/Clover/kexts/10.11/.
Now that the installation USB drive is ready, let's install OS X El Capitan!
Boot from the USB Drive
Restart your computer and boot from the USB drive (Press Esc/F8/Del to access the boot selection menu).
Use the arrow keys to select Boot OS X Install from Install OS X El Capitan (It should be selected by default). Press the spacebar and select Boot Mac OS X in verbose mode. Verbose mode means that you'll be able to see exactly what's going on under the hood as OS X attempts to boot up its installer. You'll be able to see the exact error message if booting fails.
Press Enter and cross your fingers. Clover will now boot the installer from your USB drive. This could take some time, in my case, it takes around 5 minutes (Don't worry -- the startup time is around 5 seconds after installing on an SSD).
Did it fail?
It's more than likely that the boot will fail. Don't panic (ha-ha), as kernel panics usually mean that you forgot to copy an essential kext to the EFI partition. Look up the exact error you're getting before the boot log comes to an end and search Google for a solution.
Once you find an additional kext that your system needs, you'd attempt to copy it to the EFI volume, only to discover that it's gone! Not to worry, it's just unmounted and hidden. Follow this guide to mount the hidden partition, and then, follow the Copy Essential Kexts section above to copy it to the USB drive's EFI partition.
Format the Target Hard Drive
Once the installation wizard boots, the next step is to prepare the hard drive that you want to install OS X on.
Click Continue, followed by Disk Utility.
Select the target drive to install to (not the USB drive!) and click the Erase button. Make sure to back up anything important on that drive, as it will be deleted forever.
- Set the Name to El Capitan.
- Set the Format to OS X Extended (Journaled).
- Set the Scheme to GUID Partition Map.
Click Erase to format the drive.
Install OS X to the Target Drive
Exit the Disk Utility and click Install OS X.
Click Show All Disks and select the drive you just formatted to install OS X on it. Finally, click Install.
The process takes about 25 minutes. Be patient. For me, it hung at the end ('1 second remaining') for around 5 minutes. Don't be tempted to reset or cancel the installation.
When that's done, the system will reboot. Make sure to boot from the USB device again, and select Boot OS X Install from Install OS X El Capitan once again, in verbose mode. The installation is a two-part process that continues once you re-boot into the USB drive.
Finally, after about 25 more minutes, OS X El Capitan should be successfully installed on the target drive.
Boot into El Capitan via the USB Device
After the second reboot, boot from the USB device once again, but this time, select Boot OS X from El Capitan, and select verbose mode.
Press Enter and cross your fingers again. If all goes well, you'll be presented with the setup wizard:
Take a minute to set up your new Hackintosh. Once you're done, there are a few things you need to do to finish off the installation.
Reinstall Clover on the Hackintosh Drive
In the previous step, we used Clover on our USB drive to boot our Hackintosh. This is fine, but most of us aren't going to keep that USB drive plugged in forever. Let's make it possible to boot El Capitan independently by reinstalling Clover on it.
Go back up to the Install Clover on Your USB Drive section and follow the steps again, but this time, select your El Capitan volume instead of the USB drive.
Once again, copy the essential kexts to the EFI partition that shows up after installing Clover.
Finally, make sure to add Clover EFI boot options which is possible by pressing Clover Boot Options in the Clover boot window (if there are 2 boot options -- find the one for your SATA drive). I literally spent 3 hours figuring out why Clover would not boot when I disconnected the USB drive before I figured out that I need to manually add the EFI boot options.
Now you'll be able to boot directly from the El Capitan hard drive, as it should be!
Audio and Networking
If you're lucky, audio and networking will work right out of the box. If not, you're on your own from here. You'll need to research your exact hardware (by using System Information in Applications/Utilities) and searching Google to find the right kext or installer to make it work on El Capitan.
Clover Themes
The default Clover theme is pretty ugly (no offense). Check out this theme database to improve Clover's appearance.
