SD slot for mac mini Last year I purchased a Mac Mini from MacMall. It came without a manual or  instructions.  I'm trying to find a slot in the back to install a SanDisk card to view pictures off a trail cam. The slots will not take the card directly.  Yesterday I drove 50 miles to a Best Buy and purchased an Insignia adaptor which the salesman assured me would fit any computer made. There are only two tiny slots at the back of the mac mini and the Insignia adaptor is too large to fit into either of them. Can any one offer me some advice or must I assume the mac mini will not take any SD card.  Ron
The Mac mini, since Mid 2011, has one Secure Digital (SDXC) card slot.  Prior to that, the Mid 2010 models have one Secure Digital (SD) card slot and prior to 2010 the Mac mini has no card slot.

If the flash memory card is a micro card, then to use the SD/SDXC card slot, you need an SD card Adapter as shown in the example image below.



If you do not want to use the SD card slot then you'll need a USB SD Card Reader. As an example, the Insignia™ - USB 2.0 SD/MMC Memory Card Reader - Black, which is compatible with, SD, SDHC, SDXC, microSD, microSDHC, microSDXC, MMC and MMC+ memory cards on PC and Mac, shown in the image below.
