I've had my late 2012 quad core Mac mini repaired several times under AppleCare warranty (wireless and main board twice) and the store have kindly offered to replace the whole machine... However, the new Mac minis are dual-core only, so although I'm getting a replacement, I'm not overly chuffed about the offering. I don't mean to sound ungrateful, but the reality is my old machine outperforms (when it's working) the replacement I'm being offered (2.6ghz). I mostly do processing intensive work such as movie and music editing, video conversion, and photo work. Just wondered if anyone has found themselves in a similar position and keen to hear constructive advice. Thanks!
