Question: MacBook Air Reinstalling OS: “Item Temporarily Unavailable”

I was trying to do a clean reinstallation of macOS on my MacBook Air, I erased my laptop and then when i started the reinstallation i’m getting the error message “this item is temporarily unavailable”. My laptop is installing Yosemite by default which i think is unavailable own App Store. I searched on web and tried some tutorials but nothing helped me. The laptop is not working now.. Please share a working solution for fixing this issue. Any way to install it by downloading the OS and installing on a USB then installing on my Laptop. I own multiple Mac computers.

Hey, Master2344!

Thanks for stopping by the Apple Support Communities. From your post, I understand you're attempting to reinstall your macOS software, and are running into trouble. You'd like to use a bootable installer, set up on another Mac, to install with. I'd be happy to help!


The following instructions from How to create a bootable installer for macOS - Apple Support will walk you through the steps you need:

A bootable installer can be useful when you want to install macOS on multiple computers without downloading the installer each time, or without connecting to the Internet.

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need to create a bootable installer to install macOS.

Download macOS from the App Store

  1. Download macOS from the Mac App Store. It downloads to your Applications folder as a single ”Install” file, such as Install macOS High Sierra.
    If you're creating a bootable installer for macOS High Sierra, download from a Mac using High Sierra, Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators: Please download from Apple, not a locally hosted software-update server.
  2. When the installer opens, quit it without continuing installation.

Then use the 'createinstallmedia' command in Terminal

  1. After downloading the installer, mount the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type one of the following commands in Terminal. These all assume that the installer is in your Applications folder, and the name of the volume that you're using for the bootable installer is MyVolume. If your volume is named differently, replace MyVolume with the name of your volume.

    High Sierra:

    sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

    Sierra:

    sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app

    El Capitan:

    sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app

    Yosemite:

    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Yosemite.app

    Mavericks:

    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Mavericks.app

  4. Press Return after typing the command.
  5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password
  6. When prompted, type
    Y
    to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
  7. Quit Terminal when done. The bootable installer is now ready to use on a compatible Mac. Learn how to choose it as your startup disk.

For more information about the

createinstallmedia
command used in the examples above, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:

Sierra:

/Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia

El Capitan:

/Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia

Hey there, Master2344.

Thanks for replying back to let us know you ran into some difficulty trying to use an 8GB USB drive.

Taking a look over How to create a bootable installer for macOS - Apple Support , a 12GB drive is required. Based on that, I would suggest obtaining a drive with at least 12GB of storage, and trying again. If you still run into an issue creating the installer, please reach out to Apple Support directly for additional assistance. You can do that here: Contact Apple Support .


Cheers!
