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?

This informative article will demonstrate the comprehensive guide to fix VirtualBox mistakes while installing Mac OS X. Most sites producing content about the installment of Mac OS X El Capitan or macOS Sierra on VirtualBox aren’t complete and have errors. The guide may be right and operate on a single device perfectly and with no issue. However, there are plenty of devices and various types of errors. A couple of weeks ago, we made a post on the way best to set up Mac OS X El Capitan on VirtualBox, and the traffic has different sorts of issues.
Minimum System Requirements to install MacOS X on Virtualbox:
Minimum system requirements to install MacOS X on Virtualbox are: (It will help run macOS High Sierra or later versions without any problem.)
- Minimum 2 GB memory (Recommended 8GB or higher)
- Minimum 2 cores of processors (Recommended 4 cores or higher)
- Hard disk free space 40 GB (Recommended 100GB or higher)
- Your system should support Intel or AMD VT (Virtualization Technology)
- Intel/AMD VT (Virtualization Technology) Should be enabled from BIOS setup
For fast performance, try installing macOS X on SSD rather than HDD.
Required: Enable Virtualization Technology (aka Intel VT or AMD-V). See video below.
Some key points to remember before Installing Mac OS X:
1) Intel CPU works better than AMD
2) Turn OFF Antivirus programs (Windows Defender) and Windows Firewall before starting the install
3) Set Video RAM to between 64-128MB
4) Use no spaces in VM name (ex: “MACOSX” not “MAC OSX”). Also, no punctuation. Also, re-verify:
VM Type: Mac OS X and Version: Mac OS X 10.11 El Capitan (64-bit)
(These are in Virtualbox Settings->General)
5) Suggest use wired Internet, not WiFi, for initial download/updates, etc.
6) Run CMD window as Administrator when entering command-line commands.
7) May need to start Virtualbox as Administrator.
8) Be patient during initial boot up. It runs disk checks and other repairs… and can reboot a couple of times.
9) Be sure your HD or SSD has >80GB of free space. All the updates after initial installation gobble space.
10) Black Screen? Try video RAM > 64MB and Chipset = PIIX3
11) Do not install Virtual Box Extensions “CD”
12) Before adding commands on CMD, make sure you have quit your Virtualbox.
Unkown option –cpuidset
If you get this error “VBoxManage.exe: error: Unknown option. –cpuidset. The VM hangs on boot” while adding the first code in the Command Prompt. It’s because of the double hyphen. Use Double hyphen “- – “before cpuidset.
VBoxManage error: Could not find a registered machine named Your VM Name
If you get this error “VBoxManage error: Could not find a registered machine named Your VM Name“, it is because you haven’t used the correct name of your virtual machine when adding the codes on CMD.
You need to make sure you use the same VM Name you used when creating the virtual disk.
Missing Bluetooth Controller
If you get this error, make sure you close the virtual machine before adding the CMD codes.
Guru Meditation error or Black Screen
This error is majorly seen because of two issues-
The critical error happens due to the guest operating system. It is trying to switch to the PAE mode, which is currently disabled by default in VirtualBox. PAE support can be enabled using the VM settings (System/Processor)”.
- Open VM VirtualBox
- File -> Settings -> System -> Processor
- Check Extended Features: Enable PAE/NX
OR,
For people with the black screen problem or Guro Meditationerror, change the operating system version from macOS 10.13 High Sierra (64-bit) or macOS 10.12 Sierra (64-bit) to just the Mac OS X (64-bit). If the error still exists, switch the Video Memory Size to 128 MB from Virtual machine settings. This is a significant issue with most of the users.
This version of Mac OS X is not supported on this platform Reason: Iloveapple
Make sure Virtualization Technology (VT) is enabled from BIOS.

Try to change the inverted commons throughout the virtual codes. Since you are copying the codes, you might be using the wrong inverted commas.
So, copy the codes in your notepad file, replace all the inverted commas via your keyboard and then try again.
Invalid Virtualbox Version
Make sure you add the right virtual codes. You can download the correct version codes here-
Stuck in an infinite loop on Black Screen
Try using this command as the last command on CMD-
VBoxManage modifyvm “VM_name” –cpu-profile “Intel Core i7-6700K”

Try Motherboards Chipset – both PIIX3 and ICH9 one by one
install.nsh is not recognized as an internal command
1st method:
If you get ‘install.nsh’ is not recognized as an internal or external command, operable program, or script file. You have not attached the Virtualbox Boot Image.
See, https://www.geekrar.com/fix-macos-catalina-install-nsh-isnt-recognized-as-an-internal-error/
2nd method:
If you then get messages along the lines of ‘macOS Install DataLocked FilesBoot Filesboot.efi’ missing or not recognized:
run setup.nsh
now run, fs0:SystemLibraryCoreServicesboot.efi
and all should now spring into life.
3rd method:
- At UEFI prompt: Type exit
- You’ll be brought into an EFI text-mode GUI.
- Select Boot Maintenance Manager and click.
- Select Boot From File and click
You should see two entries in a list (they are cryptic looking PCI bus paths).
The first PCI path in the list is probably the boot partition that doesn’t contain bootable firmware. The second PCI path is probably to the recovery partition, the one you need to boot from. If the 2nd partition isn’t the recovery partition, look under the paths in the list to see if one of them is it. If the recovery partition isn’t present and valid, these instructions won’t work.
Click the 2nd entry, you should see (and then click):
macOS Install Data
Then click:
Locked Files
Os X El Capitan Not Installing On Pc
Then (if present), click
Os X El Capitan Install
Boot Files
And finally click:
boot.efi
The installation will continue, or you will boot into the OS or get the Recovery utility menu (where macOS can be reinstalled from or Disk Utilities run). The ambiguity of that last statement is I did that awhile before writing this comment, and I don’t recall what I booted into first, only that it worked and was not hard to figure out what to do at that point. If you have a recovery partition, to boot directly into the Recovery Mode, turn on the Mac and immediately press and hold (⌘)-R
Set screen resolution
Use the following command-
cd “C:Program FilesOracleVirtualBox”
VBoxManage setextradata “VM Name” VBoxInternal2/EfiGraphicsResolution 1440×900
If you are still facing some issues, try using VMWare to install macOS on your Windows. When your current PC does not support Virtualbox and its configurations, try switching to VMWare. The process for it is relatively painless.
