More recently though, Apple has largely phased-out built-in SD card readers.

Mac mini (Mid 2010) features a rear SDXC slot, backward compatible with SD-SDHC cards.

Here are some of the fastest SD cards for Mac currently available:īeginning in 2009 Apple added a high-speed SD-SDHC slot to these Macintosh computers: Class 10 SD cards have the highest performance.
The slot on Macs accept cards that are either Standard SD (Secure Digital) up to 4 GB, SDHC (Secure Digital High Capacity) 4 GB to 32 GB, and SDXC (Secure Digital eXtended Capacity) cards in 32, 64, or 128 GB sizes. Some connect internally via USB, others interface directly with the PCI bus for faster performance. Stay tuned for additional details as they become available.Combining both speed AND high capacity - those owning select models of Mac mini, Apple MacBook Pro and Air, as well as Aluminum iMac models may have a built-in SD memory card slot reader. One user reported that the current macOS Monterey 12.1 beta resolved the issue, while another user reported that the issue remained under the beta. Many of the reports are about older SD cards and there may be a particular issue with some 128GB cards, but for the most part, complaints are all over the place in terms of SD card brand, speed, and capacity. Other readers stated that Apple replaced their MacBook Pro notebooks and did not continue to have issues with the new machines.

Some readers who reached out to Apple for help were informed that the company is aware of the issue, and that a fix is en route via a future software update, although it’s unknown if this is due to a hardware or software issue. 100% of my cards work perfectly via a dongle. Sandisk, Sony, Samsung, 16GB, 32GB, 64GB, 128GB, 256GB, UHS-I, UHS-II, micro-SD, FAT32, exFAT, makes no difference. Reformatting, even to all other possible formats, makes no difference. The only thing that is consistent is that if a card works, it always works, and if a card does not work properly it never works properly. I tried many cards, and could find no pattern of brand, size, type, format, age. Other readers have reported that using a USB-C SD card reader can work when the built-in SD card reader fails: Given the thread, the card’s formatting doesn’t appear to be the central issue, though it could be a factor. In other cases, the Finder will crash or the SD card will take several minutes to become accessible. In some situations, there’s an error message when attempting to use the SD card. All my cards work as expected in my 3 other USB card readers. I tried reformatting them w/ the MBP and that didn’t seem to make a difference. These are all Sandisk Ultra cards, both XC and HC, that were formatted in my camera. Half the time it’ll recognize the card successfully (though it takes anywhere from 30s to 1m) and half the time it’ll throw an error.
Just seems to be super flakey and inconsistent. Some SD cards crash and can’t be accessed, while some have unusually slow transfer speeds. In a long complaint thread, MacRumors readers have detailed the issues that they’re having with some SD cards, and there seems to be little consistency between reports and affected SD cards. As nifty as the new 14-inch and 16-inch MacBook Pro notebooks might be, there might be some bugs with the SD card readers.
