Scenario:
- Purchase MacBook Pro on eBay which comes with no hard drive.
- You've never owned a Mac before, nor an iOS device. (So no Apple ID.)
- Install your HDD/SSD into your new MacBook Pro.
- Apple will allow the download and install of the latest OS to someone with no Apple ID using Internet Recovery?
- Internet Recovery will allow the reformatting of any hard disk installed into the bay (to discount for things like NTFS, FAT32)
