Hey guys, Ive been a PC user and I'm switching over to apples. Basically I plan on purchasing a Macbook and want to replace the HDD. Curious on the process of installing OSX on a unformated drive. I know for PCs you have to go into bios and select CDROM as the boot drive. What is the process for a Mac? Also when purchasing a Macbook will I be given the OSX install disc? Thanks!
