Finally got my Switch (the new updated version) with the Neon joy cons.
I've been trying to sort out my SD card, but not having much luck with the storage. Its a 64 Gig Sandisk Ultra which I was using for images for my Raspberry Pi.
I put in into my Mac to check how much space I had left and weirdly it showing about 20 Meg. Opened Funter to show hidden files and deleted everything on the card, still hardly any more space. So formatted the card using Disk Utility (ExFAT) and as seen below it is showing 43Meg total storage space.
Even put it into the Switch just incase and still the same.
