Data transfer from old Mac
I have a 10-year-old iMac that has been in storage for the last three years since we moved to Ireland. I'm going to buy a new one, but I'm wondering about the best way to get photos, documents, etc. transferred from the old one. I have a Time Capsule for it, but I could also get a large thumb drive. I don't want to transfer any programs, etc., just the data. What's the best way to go?
