I am swapping the 160gb HD for a Seagate 500gb 7200 HD in my new 13" MacBook Pro. Before doing so I will back up with Time Machine to my external drive. From what I understand, after installing the new HD, I will boot up and run the OS disc that game with my MacBook, then run Time Machine to restore my files. My question is, will Time Machine also reinstall iWork? I no longer have the disc for it and need to know if I will have to get back my copy. Will it also install other program such as MacTheRipper, Toast, etc. or will I also have to redownload these too?? Also, will the OS remember all of my system preferences or will I have to reselect them?? Are there any tutorials on here or YouTube for this reinstallation and recovery of a hard drive?? I searched but came up empty handed. Any guidance is greatly appreciated!!
