I got an apple laptop at a yard sale last weekend. It has to have a password to get into the system, we don't have it. I would just like to reload it with a free copy of mac osx to see if it even works. If it works ok I will purchase the operating system for it. But I don't want to spend the money on a new operating system if it doesn't work. I'm a single mom and don't have the money to get one if it doesn't even work. Thank you.
