Os X El Capitan Cannot Be Installed On Macintosh Hd Computer
Download El Capitan Installer

Start up from macOS Recovery

I want to reset my iMac (late 2014, 1 TB Fusion Drive) to factory settings. As I want to set it back to Yosemite, I am using Internet Recovery (Command-Option-R) as I have installed El Capitan in the meantime. I was able to erase the HDD just fine in Recovery Mode Disk Utility, but now I am stuck. The OS X install dialog shows no available drive. The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion or has a Mac preloaded with OS X Mavericks, Yosemite, El Capitan, or macOS Sierra. Download the Application from the Mac App Store using your Apple ID on any Mac or functional computer running OS X 10.7.5 or later.

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

Macbook Pro 13' 2015 with OS X Yosemite on board. I've been trying to install OS X El Capitan, but always get the following message: 'This copy of the Install OS X El Capitan application can't be verified. It may have been corrupted or tampered with during downloading.' By the way this is not a date time issue, date is correct on my computer.
Once the Mac is connected to the internet, from the OS X Utilities screen choose “Reinstall OS X”. Select the target hard drive to re-install OS X onto (typically “Macintosh HD” but varies per user) – if the Mac has a FileVault password set choose to “Unlock” and enter the FileVault encryption password before proceeding further.

Intel processor

Make sure that your Mac has a connection to the internet. Then turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.

If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password.

Reinstall macOS

Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.

Follow these guidelines during installation:

If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
If the installer 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 first.
If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, 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.

Other macOS installation options

When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:

On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.

You can also use these methods to install macOS, if the macOS is compatible with your Mac:

Use the App Store to download and install the latest macOS.
Use the App Store or a web browser to download and install an earlier macOS.
Use a USB flash drive or other secondary volume to create a bootable installer.

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

Mercedes wis on mac. 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.

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”

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

Then (if present), click

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
