What is SD?
SD describes devices that conform to SD standards for non-volatile memory cards. See the SD Association website for details.
Are there size limitations for the cards that can be inserted into the SD slot?
Yes. The SD card specification for a memory card is 32mm by 24mm by 2.1mm. You can also use thinner cards, such as MultiMediaCards (MMC). Avoid using cards that have a thickness greater than 2.1mm, as they might damage the SD card slot if you try to insert them.
Which SD card formats work in the SD card slot?
Cards that conform to the SD 1.x, 2.x, and 3.x standards should work. The SD card slot can use:
- Standard SD, 4MB to 2GB
- SDHC (Secure Digital High Capacity), 4GB to 32GB
- SDXC, 4GB to 2TB
- MMC (MultiMediaCards)
- UHS‑II, up to 2TB (iMac Pro only)
You can use a passive adapter like the one shown here to make MiniSD, MicroSD, and higher density formats like MiniSDHC and MicroSDHC conform to the width and thickness specifications listed above:
How fast can my Mac read or write to an SD card in the SD card slot?
Mac notebooks use the USB bus to communicate with the SD card slot. They have a maximum speed of up to 480Mbit/s. Mac desktops use the PCIe bus to communicate with the SD card slot. Desktops can transfer data at a faster rate.
Check the packaging that came with your SD media to determine the maximum transfer rate that your specific card uses.
To determine the maximum transfer speed of your Mac, you can use System Information. Choose Apple () menu > About This Mac and then click System Report.
If you use a Mac notebook:
- Select Hardware, then select USB.
- Select Internal Memory Card Reader and look for the Speed entry.
If you use a Mac desktop computer:
- Select Hardware, then select Card Reader.
- Look for the Link Speed entry. Computers that use the PCIe bus express their speed as GT/s.
Does the SD slot work with cards that exceed 32GB?
Yes. However, most media manufacturers preformat the media using common block-and-cluster sizes that don’t approach the theoretical limits of a given file system.
Most SD cards use the FAT32 file format, and preformatted FAT32 SD media is commonly available up to a capacity of 32GB. Media that exceeds 32GB usually uses the exFAT file system, while some smaller capacity cards use the FAT16 file format. Preformatted FAT16 media is generally available up to a capacity of 2GB.
If you use OS X Snow Leopard 10.6.5 or later, you can find out which file system you’re using:
- Insert the media into the SD card slot.
- Choose Apple menu > About This Mac.
- Click System Report.
- In the Hardware section, click Card Reader, and find the File System field.
Will the SD card slot work with SD cards that use the exFAT file system?
Yes. Any Mac that has an SD card slot and is running OS X 10.6.5 or later can use the exFAT file system.
exFAT is also supported in Boot Camp with Windows 7, 8.1, or 10 on any Mac made in 2011 or later with an SD card slot.

You might have to format a card that’s larger than 32GB with exFAT if you want to use it with a digital camera, GPS, or another device. When in doubt, format the card in the device that you intend to use it with.
