This refurbished iMac arrived looking absolutely brand new. The 5K Retina screen is breathtaking, the computer is a lot more than I'm worthy of, I love it!But there was a problem. The computer arrived with the hard drive improperly formatted. The whole system was running from the 28GB Flash disc, and the 1TB SATA disc was completely locked up. No place to put the data! Tech support tried several times to help me sort it out via email, but I was out of my depth. So I took it to a local computer repair guy (certified on Mac). He was able to put everything in the right place and get it talking with itself, took an hour, cost $45. WORTH IT!My old iMac is ten years old and still on active duty. So I figured buying a 2017 refurb iMac was a good bet. It'll last as long as I need it to, and the money I saved from buying a refurb instead of new is going into the New Camera jar. Bonus!
