iPhone Backup before Reformatting

[billchase2]

What iPhone data on my Mac needs to be backed up before I reformat? I've never reformatted my Mac before and it's definitely time. I'm just not too sure what to expect after everything is erased and I connect my iPhone to iTunes for the first time.

That's correct. I'm not restoring my iPhone, I'm reformatting my computer.
