First, make sure the memory card reader is compatible with your computing system. Older readers might not work with newer operating systems, for example. Second, make sure the USB cable you’re using for the connection isn’t broken. Next, try a different USB connection slot on the PC, as the reader might not be drawing enough power from the connection slot you used originally. You also might need to download the latest software and drivers from the memory card reader manufacturer’s Web site.
A final word of warning, MacOS needs to be hacked for the card to be recognised and while Thunderbolt is a hot-pluggable standard, unplugging the Thunderbolt box with a GPU while the mac is running causes a Kernel Panic that requires a restart to clear.

Reader Doesn’t Recognize SDHC Cards
Credit card reader compatiable for mac. Some older memory card readers won’t be able to recognize the SDHC memory card format, which allows for SD-type memory cards to store 4 GB or more of data. Memory card readers that can read SD-type cards of 2 GB or less -- but that cannot read cards of 4 GB or more -- probably are not SDHC compatible. Some memory card readers might be able to recognize the SDHC format with a firmware upgrade; otherwise, you’ll have to purchase a new reader.
The External Memory Card Reader Doesn’t Seem to Be Moving Data as Fast
It’s possible that you have a reader designed for use with USB 2.0 or USB 3.0 that is connected to a USB 1.1 slot. USB 1.1 slots are backward compatible with USB 2.0 and USB 3.0 devices, but they cannot read the data as fast as a USB 2.0 or a USB 3.0 slot. USB 1.1 slots cannot be upgraded with firmware, either, so you’ll have to find a USB 2.0 or USB 3.0 slot to achieve faster data transfer speeds.
My Memory Card Won’t Fit into the Reader
If you have multiple memory card slots in the reader, make sure the slot you’re using matches your memory card. Also, make sure you’re inserting the memory card correctly; with most readers, the label should be facing upward as you insert the card. Finally, it’s also possible that the reader isn’t compatible with your type of card.
My Memory Card Doesn’t Seem to Work After I Used It In the Reader
First, make sure the reader didn’t leave any grime on the memory card’s metal connectors that could affect the card’s performance. Also, make sure the connectors aren’t scratched or damaged. Finally, it’s possible the memory card has been corrupted. If you unplugged the memory card reader while the memory card was being read, causing a loss of electrical power to the card, it’s possible the card is corrupted. You should be able to fix the problem by formatting the card, which (unfortunately) will cause all of the data on the card to be erased.
No Power to the Memory Card Reader
If you're using an external memory card reader with your computer, it will need power through the USB connection. It's possible that some USB ports on your computer don't carry enough electrical current to power the memory card reader, so the reader won't work. Try a different USB port on the computer to find one that can provide the proper level of power.
Check the Cabling
Another potential reason your memory card reader could be failing is because the USB cable you're using to connect the reader to the computer could have some interior damage, causing it to be unable to work. Try replacing the cable with another unit to see if the old cable is causing the problem with the memory card reader.
By now there are countless flash cards designed to sit perfectly inside the MacBook Air’s SD card slot and boost the laptop’s storage as an extra onboard drive. But the TarDisk Pear is the first to actually merge with a MacBook’s SSD, creating a single hybrid drive for easier file management.

Made with a brushed aluminum housing so that it blends into the rest of your MacBook Pro or MacBook Air when inserted, the TarDisk Pear includes a built-in automatic installer that essentially turns the flash card and your laptop’s native SSD into a single Fusion Drive, using Apple’s own terminology for the clever hardware trick.

With the TarDisk Pear installed instead you don’t have to manage a pair of drives on your laptop and decide how to distrubute your videos, photos, music, or important work files amongst them. Instead, your MacBook just thinks its SSD suddenly has way more capacity at its disposal.
To ensure there’s minimal loss in performance, the software ensures the MacBook’s SSD is always the preferred place to store files, assuming there’s still space left. But when the extra capacity of the TarDisk Pear is required, the software will try to only keep less frequently used files on the flash card. The system’s read/write buffer is also maintained on the SSD, again, to help maximize the performance of the hybrid drive.

According to TarDisk’s own benchmark tests, MacBooks actually show the same, or slight improvements to disk performance with the TarDisk Pear installed. So while the actual hardware in the flash card might not perform as well as the SSD drives Apple uses do, the extra storage your laptop is gaining still ends up being an overall boost to your system.

There are a few important caveats to note, though. For starters, when using an SD card as an extra storage drive for your MacBook that’s just full of random files, you’re free to remove it whenever you want. But when that SD card is permanently tied to your MacBook’s SSD, and might hold crucial system files, you’re not going to want to pop it out. Once installed, you should probably consider your MacBook’s SD card slot off limits, and get yourself an external USB card reader as an alternative.
It’s also not a cheap upgrade. The 128GB version of the TarDisk Pear will sell for $149 when available next Tuesday, while the larger 256GB model comes in just shy of $400. Consider that bumping a new 13-inch MacBook Air from a 256GB to a 512GB SSD on Apple’s website when ordering is just a $300 upgrade. So if you’re spec’ing a new machine, spend the extra money up front to boost its SSD capacity. But if you’re trying to prolong the life of an existing MacBook, this is almost certainly cheaper and easier than upgrading the guts.
