Reinstallation Crashes
Bought a used Mac book Pro 15" from mod 2009 and to clear the computer I attempt to reinstall osx/Yosemity. However, after downloading for three hours the installation process halts and nothing further happens... Even after 9 hours waiting time. Any solutions for a complete and clean reinstallation of the used Mac book Pro?
MacBook Pro, OS X Yosemite (10.10.4), 15" mid 2009
