Is there a way to determine the version of OS X installed on the system from the recovery tool? Is there a way to obtain a disc copy (without paying as we already have it installed) of Mavericks or Yosemite so that I can reinstall from media? Finally, is my only option now to do an Erase and then Install OS X from the Internet Recovery tool? Nov 29, 2017 Install older OS X onto an external drive.

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. Click the gear icon labeled Options, then click Continue.
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.
Hi all
I am trying to reinstall OS X Yosemite onto a MacBook Pro Late 2008 version. We are selling the Mac, and have conducted the steps described in 'What to do before selling or giving away your Mac', i.e. deauthorizing from iTunes etc, and erasing all data from the harddrive. I am using an ethernet connection.
Install Os X Yosemite Download
When trying to install Yosemite, after entering my Apple ID and password, I keep getting the message 'This item is temporarily unavailable'.
I found members stating that this can be due to the App Store being flooded with requests, but this has been going on for three days now, and I find that a bit unusal.. Especially since the first installation onto our old Mac took one evening..
Thank you all for any help and advice you can provide!
