Reset macbook
Hi I bought MacBook Pro mid 2010 from someone, it was working just fine until I decided to reset it, keeping in mind 'I know nothing about macbook...', I followed instructions on how to reset it, pressed option+command+shift+R buttons. Then OS X Utilities pop up, I cleared MacOS on Disk Utility, I got back to reinstall OS X, OS X EI Capitan 10.11 showed up, clicked continue, followed instructions, then at the end when i try to install it, the message "This item is temporarily unavailable" pops up.
I really don't know what to do from here, please help. Thanks.
MacBook Pro 13″, OS X 10.11
