New harddrive installed but need to install new osx with no cds
I'm having a new solid state drive installed in my iMac (late 2010 model). They want to charge $70 to install the OS and I know I should be able to do that myself. I purchased the machine from someone and wasn't given any cds for the OS or anything. Is it possible to install the OS on my iMac without them and, if so, how?
Es esta una buena pregunta?
