Mac Ios For Macbook Pro A1278 Recovery Download

| Posted on by



If you’re still using a Mac OS X the time will come when your computer won’t boot, or a problem may arise where you can’t take control of the device, and booting from an OS X installation media will be required.

  1. While it hasn't gotten as much attention as iOS 10, Apple's big 10.12 update to their Mac operating system is finally out for all to enjoy—and you can download it for free from the Mac.
  2. High dynamic range (HDR) video playback is supported by the following Mac models: MacBook Pro (2018 or later) iMac Pro (2017 or later) Mac Pro (2019) with Pro Display XDR. Requires a MacBook Pro or MacBook Air with Touch ID, an iPhone 6 or later with iOS 10 or later, or an Apple Watch with watchOS 3 or later.
  3. So I wiped the HD on my mid 2010 MacBook Pro, and trying to reinstall OSX via Recovery I get this error: the feature is not available at the moment and to try later. I already had a chat with the support and they said that they can't give me any help, not even paid, because the MacBook is listed as vintage and to try the online recovery, I.

This is why it’s recommended that you make a Mac OS X bootable USB when your Mac is in working conditions. However, if you find yourself on a scenario where your device (iMac, MacBook Pro, Air, Mac Pro or Mini) is not responding and you happen to have a Windows 10 device, then you can still be able to make a USB bootable installation media for your Mac OS X to reinstall the operating system using the Recovery Assistant.

MacBook Pro 13' Unibody Mid 2012. Released June 2012, Model A1278. Intel processor with Turbo Boost, Up to 512 MB DDR5 Video RAM.

These instructions will also work for Windows users who are running Mac OS X on a virtual machine and need to upgrade to the latest version. For instance, to OS X Yosemite.

Requirements

Before you dive into this guide, you’ll need a few things:

  • A broken Mac computer with Mac OS X.
  • A trial copy of the TransMac software.
  • One high quality USB flash drive with 16GB of storage.
  • A copy of Apple’s macOS (DMG file).

Now that you have all the necessary ingredients, you’re ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below.

Create Mac OS X bootable USB installation media

Before you can use TransMac, you first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you’ll need to use the Diskpart command-line utility on Windows 10.

Setting up GPT partition

Use these steps to set up a USB drive with a GPT partition:

  1. Open Start on Windows 10.

  2. Search for Command Prompt, right-click the top result and select the Run as Administrator option.

  3. Type the following command to open Diskpart and press Enter:

  4. Type the following command to determine the USB flash drive and press Enter:

  5. Type the following command to select the storage and press Enter:

    Quick tip: The select disk 1 command as an example, but you have to replace 1 with the number of the flash drive you want to use.

  6. Type the following commands to delete everything from the USB thumb drive and press Enter:

  7. Type the following command to convert the drive into a GPT partition and press Enter:

  8. Type the following command to select the new partition and press Enter:

After you complete the steps, the USB flash drive from MBR to GPT format, you can use the steps below to create a bootable USB installation media to install Mac OS X.

Use these steps to create a bootable media to install Mac OS X:

  1. Download and install a copy of TransMac.

    Quick note: TransMac is a paid software, but it has a 15-day trial solution, that give us more than enough time to move the DMG files to the USB drive from Windows. (If you want to support the developer, you can purchase the full version.)

  2. Insert the USB drive that you’ll use to fix your installation of OS X. (Remember that all the data in the USB will be erased. Make sure you take off any important documents.)

  3. Right-click the TransMac software icon and Run as administrator. (You’ll be prompted to Enter Key or Run, because we’ll be using it once, click the Run option.)

  4. On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive that you’re intending to use to reinstall Apple’s OS X and select the Restore with Disk Image option.

  5. In the warning dialog box, click the Yes button.

  6. Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click the OK button to create a bootable USB of the operating system.

    Now, you’ll have to wait a long time. No kidding. It could take one or two hours to complete the process depending on your computer and other variables.

Once your bootable USB installation media is ready, remove it and insert it into your Mac, power it on, holding down the Option key, and select the USB you just created to reinstall Mac OS X.

If you’re having issues trying to create a bootable media, you can get a USB flash drive that comes with Mac OSX ready to install.

Start up from macOS Recovery

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, which includes a gear icon labelled Options. Select Options, then click Continue.
  • Intel processor: make sure your Mac has a connection to the Internet. Then turn on your Mac and press and hold Command (⌘)-R immediately until you see an Apple logo or another image.

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

Reinstall macOS

Select Reinstall macOS from the utilities window in macOS Recovery and then click Continue and follow the installer's instructions.

Follow these guidelines during installation:

  • Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac may restart and show a progress bar several times, and the screen may be empty for minutes at a time.
  • If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
  • If the installer can't see your disk or notifies you that it can't install macOS on your computer or volume, you may need to erase your disk first.
  • If the installer is for a different version of macOS to what you expected, find out about other installation options, below.
  • If the installer offers you the choice between installing on Macintosh HD or Macintosh HD – Data, choose Macintosh HD.

When the installation is complete, your Mac may 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 the setup process.

Other macOS installation options

By default, macOS Recovery installs the latest macOS that was previously installed on your Mac.* You can get other macOS versions using one of these methods:

  • On an Intel-based Mac, you can use Option-Command-R at startup to upgrade to the latest macOS that is compatible with your Mac. Exceptions:
    • If macOS Sierra 10.12.4 or later was never previously installed, you will receive the macOS that came with your Mac, or the closest version still available.
    • If your Mac has the Apple T2 Security Chip and you never installed a macOS update, you will receive the latest macOS that was installed on your Mac.
  • On an Intel-based Mac that used macOS Sierra 10.12.4 or later previously, you can use Shift-Option-Command-R at startup to install the macOS that came with your Mac, or the closest version still available.
  • Reinstall macOS from the App Store instead of using macOS Recovery. If you can't install the latest macOS, you may be able to install an earlier macOS.
  • Create a bootable installerand then use it to install macOS on your Mac or another Mac.

* If you've just had your Mac logic board replaced during a repair, macOS Recovery may only offer the latest macOS compatible with your Mac. If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery may only offer the macOS that came with your Mac, or the closest version still available.
