A reader with the nom de Internet of Bass Hound writes in with a set of interlocking problems:
Their new computer has a 128GB drive while the old one was 512GB. They have a Time Capsule backup and wonder if they can make choices while restoring the backup.
While they’ve opted into iCloud Photo Library, they “have not, however, joined Apple Music because I don’t want to pay the ongoing fee.”
Finally, they’d like to “add all my media—music, movies and possibly pics—to an external drive.”
This is not an uncommon collection of questions, so I’ll do my best to knock them all out.
First, you can use Migration Assistant instead of OS X Recovery to restore just Applications, certain user (Home) directories, and other files. That may be a good place to start with a fresh computer.
