hello, got a new imac this past year 10.6.7, trying to use an older macmini 10.4.11 as a backup, just reinstalled os to the mini, did a total clear out . and want to send itunes/iphoto library to mini, about 30 gigs, spent the past couple days reading other posts and experimenting connecting the 2 machines via ethernet , but cant seem to figure it out, any simple directions? i can do it with a seperate external harddrive, but should be simple enough with just the 2 computers. thanks for help
