In this article we'll run through the steps necessary to create a bootable installer of the Mac operating system, whether it's so you can install the latest version of the macOS on multiple Macs. I have a 2010 Macbook Pro that has a wiped hard drive. When I turn it on it takes me to an internet recovery option that leads to this error: 'Can't download the additional components needed to install Mac OS X.' I downloaded High Sierra OS onto a USB. The computer doesn't seem to recognize the USB.
Hello - Thank you for your time.
So my 2010 MacBook Pro A1278 got wiped and I am currently trying to download OS on the laptop.
I keep getting an error in recovery mode to download Lion (need additional components error), so I made a bootable drive on my other Mac with High Sierra.
I was finally able to start my computer with the flash drive, but when I tried to download High Sierra on to my computer it did not give me the option to download it to my hard drive, it was grayed out.
Any ideas? I’m out of them. Thank you.
Is this a good question?
Summary: Are you dealing with a crashed Mac or unable to boot your Mac machine?
Before you think of reinstalling macOS or doing a hardware fix, ensure that you’ve rescued your data from the device.
This blog will guide you through an easy process of creating a bootable macOS Mojave USB install drive or a recovery USB drive using Stellar Data Recovery for Mac software.
The USB recovery drive will help you to recover the data from your crashed or non-booting macOS. So go ahead, download the free software trial now.
Minimum requirement: 8 GB USB flash drive, Mac, and Mojave installer.
- Download macOS Mojave 10.14 from App Store.
- When the download completes, quit the installer, as it will launch itself automatically.
- Locate the installer from the Applications folder (copy it to the desktop if you desire).
- Connect the USB flash drive with at least 8 Gigabytes storage space to your Mac.
- Open Terminal and enter the next command: sudo (drag and drop the installer from application folder to locate its path) –volume (drag and drop the USB flash drive from the Mac volumes to specify its path) –nointeraction –downloadassets
Warning: The command erases the flash drive so check there are no stored files; backup the files, if they exist, before executing the sudo command.
- Type the administrator password when prompted. The Terminal creates the installer drive on the opted USB flash drive.
Note: Erase the flash drive to HFS+ (Mac OS Extended (Journaled)) but not APFS.
Usage of USB Install Drive
- Backup the entire drive before performing a clean install on your Mac machine.
- Connect the USB install medium.
- For T2 security chip supported by 2018 MacBook Pros and iMac Pros, you need to “allow booting from external media” from Startup Security Utility. Alternatively, hold the option key and reboot the Mac then use the arrow key to select the USB flash drive as an installer.
- Allow the computer to boot from the USB flash drive. Deploy the macOS Mojave software.
Installer Tips
- When Apple releases newer Mojave versions, re-download the new installer and recreate installer drive to keep it up to date.
- Keep the installer drive on a safe place so that you can use it as an external recovery drive when your Mac gets into trouble.
Data Recovery on macOS: Why We Need It Here
While performing macOS upgrade or fresh installation, you must back up data to an external storage medium. Backup helps to restore all the data back to Mac’s internal storage drive, containing the new macOS. If you do not have a backup, then you end up losing all your data stored in the Mac drive. This is because, during macOS installation, the installer erases the startup partition completely or the entire storage drive, depending upon your choice during installation.
If No Backup: What Is the Recourse?
There are chances that you did not take backup to an external backup drive, or in the rare case, the backup itself was lost, damaged, or unavailable. In such scenarios, you can rely on a data recovery software—such as the editor’s choice Stellar Data Recovery Professional for Mac—that can recover your lost data after macOS Mojave installation. The software works flawlessly with the older & newer version of MacBook Pro, MacBook Air, iMac, iMac Pro, and Mac Mini etc.
The Process of Data Recovery
The process of data recovery is straightforward. Follow the steps mentioned below to get back the data stored in the drive—erased completely after installing the new macOS Mojave:
1. Download and install the Mac data recovery utility on the same system where you have installed the new macOS Mojave (due to the negligible storage requirement of the utility).
2. Alternately, you can download and install the utility on a different Mac machine, then connect the internal drive as an external device by removing it from the affected Mac.
3. Launch the data recovery software to interact with its lucid graphical user interface.
4. In the Recover Data module, select the type of data and the location of the storage drive.
5. Toggle on the Deep Scan switch from the bottom left and click the Scan
6. Allow the scan to complete, which may take some time—depending on the storage size and the condition of the affected drive.
7. Preview the recoverable files if you want, then select all the required files and click the Recover
8. Specify a different external backup drive with size greater than the drive where you are performing the data recovery then click Save.
When the save process is complete, verify the recovered data from the backup storage drive. Copy the files back to your Mac or an externally used Mac drive (reconnect the drive to the Mac once the restoration process is over).
