So... The hard drive on my parents 2007 iMac failed last week, and I've bought a new SSD to replace it with. Once the new SSD is fitted, will I be able to use a bootable USB drive with the Mavericks installer on it to install Mavericks to the SSD? I'm not convinced the SSD will be recognised as it will be straight out the box and unformatted. I've done a bit of googling but can't find an answer to this scenario. Hope one of you can help!
