I decided to wipe out everything and do a clean install for Mavericks for my iMac (late 2011). I went through the process of reformatting the HD. I go into Reinstall OS X and move through the process of providing my Apple ID and password. All looks fine and the I get the message “This item is temporarily unavailable”. Mar 29, 2018 This will install the newest OS that the computer is compatible with. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Quit Disk Utility. Then install the OS.When the computer restarts, you can use Setup Assistant to restore your data from Time Machine. Got to reinstall OS X Mavericks. Two options, Macintosh HD or Recovery HD (option Greyed out) if you click on it, it says locked. So I’m guessing it’s Macintosh HD, click on to install, asks for Apple User ID and Password. When I type details in, it comes up This item is temporarily unavailable, please try later. My Mac OS X version is 10.10.1 Yosemite. I wanted to install Java 7 on my Mac. So when I try to install it says 'you need Mac OS X version 10.7.3 and later'. So I found the following from the web to.
Feb 26, 2016 I have erased my HD and tried to install OS Yosemite on MacBook Pro mid 2009. But keep getting this message 'This item is temporarily unavailable.' I've tried many proposed solutions but none seem to.
Start up from macOS Recovery
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labelled Options, then click Continue.
Make sure your Mac is connected 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 and enter their administrator password.
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 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 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 may restart and show a progress bar several times, and the screen may be empty for minutes at a time.
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
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'll be offered the macOS that came with your Mac, or the closest version that is still available. If you use Option-Command-R during startup, in most cases you'll be offered the latest macOS that is compatible with your Mac. Otherwise you'll be offered the macOS that came with your Mac, or the closest version that is still available.
- If the Mac logic board was just replaced, you may only be offered the latest macOS that is compatible with your Mac. If you've just erased your entire startup disk, you may only be offered the macOS that came with your Mac, or the closest version that is still available.
You can also use these methods to install macOS, if the macOS is compatible with your Mac:
Temporarily Unavailable Meaning
- 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.
