Start up from macOS Recovery
Is there a way to download a disk to re install the OS after I get a new HDD in it? If there is how does licensing work? I am used to windows computers where the Key is on the bottom of the machine. I don't see a key of any kind. I'm also not sure what version of OSX it should be running. OS X Recovery Disk Assistant lets you repair disks or reinstall OS X without the need for a physical disc. The tool allows you to create OS X Recovery on an external drive that has all of the same capabilities as the built-in OS X Recovery: reinstall Lion or Mountain Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari. From Apple's website: 'To create an external OS X Recovery, download the OS X Recovery Disk Assistant application. Insert an external drive, launch the OS X Recovery Disk Assistant, select the drive where you would like to install, and follow the on screen instructions. 1-16 of over 1,000 results for 'macbook pro recovery disk' Skip to main search results.

Select Reinstall macOS from the utilities window in macOS Recovery, 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 might restart and show a progress bar several times, and the screen might 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 it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer is for a different version of macOS than you expected, learn about other installation options, below.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.

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 previously used macOS Sierra 10.12.4 or later, 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 might be able to install an earlier macOS.
- Create a bootable installer, 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.
