After downloading OS X 10.6.8 to Snow Leopard, my DVD player no longer works. I get a -10960 Error installation error. The DVD player is v.5.4 running on MacBook Pro 2GHz (older 2010). Can I download 10.6.8 to my external hard drive and reinstall to MacBook? Would that even have the DVD player? Would I have to erase and install. I do have a retail version of OS X 10.6.3. Or, is there an Apple DVD stand alone download specific to 10.6.8? Have not seen this discussed in other forums. Any help would be appreciated.
