Yeah, I thought the pushback against AMD for initially saying they wouldn't support 4th Gen Ryzen was over the top. The fact they kept compatibility as long as they did, given how much the Ryzen line changes since the first iteration of it, is really quite remarkable. I feel like people really didn't understand that fact when they were complaining about it. Plus, why would you want to use such a new processor on a 3 year old MB? That would be like keeping a race horse tied up in the stables...
