I have a micro SDXC memory card and I need a SDXC card Tray in order to put this card into my Macbook pro. Where do I find this tray for purchase?

No tray— simply an adapter that accepts the micro SD in the the blank SD card adapter.

Any office supply store/ University book store/ Walmart/Bestbuy etc will have this adapter or on-line:
