I wonder if anyone might be able to help with a dilemma I have. I am running Yosemite 10.10.5 and I need a portable backup drive that is compatible with my OS. I bought a Lacie unit last month (Cosmetically identical to one I already own) only to discover that it wasn't compatible. It would seem my OS is rather old. I don't want a a refurb' or used one, so where do I get one. Any ideas would be very welcome. It seems odd to me that older OSs would be incompatible given the nature of backup drives. They are intended to store saved data, which maybe for years!
