I just recently bought a new Macbook Pro 15" 2015 2.2GHz 16gb ram 256SSD and it's running El Capitan. I can't get the machine to recognize my external hard drive. I've used the external Hard Drive on several other computers(all macs) without issue and even now when I plug the external Hard Drive on my Mac Mini it works just fine. The external Hard Drive is formatted as ExFat. I've already contacted apple without getting a solution just a go to the genius bar suggestion. So any help is appreciated.
