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 on 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 may 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, 4 MB to 2 GB
- SDHC (Secure Digital High Capacity), 4 GB to 32 GB
- SDXC, 4 GB to 2 TB
- MMC (MultiMediaCards)
- UHS‑II, up to 2 TB (iMac introduced in 2020 and iMac Pro only)
You can use a passive adapter (like the one shown here) to make MiniSD, MicroSD and higher density formats, such as 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 480 Mbit/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're using a Mac notebook:
- Select Hardware, then select USB.
- Select Internal Memory Card Reader and look for the Speed entry.
If you're using a Mac desktop computer: Encrypt single file mac.

- Select Hardware, then select Card Reader.

Does the SD slot work with cards that exceed 32 GB?
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 32 GB. Media that exceeds 32 GB 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 2 GB.
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.

How does my Mac use the media inserted into the SD card slot?
Your computer recognises a card inserted into the SD card slot as a USB storage device. You can mount, read from and write to the SD card just like you can with any other USB storage device.
I put the card in the slot, but it didn’t mount. What should I do?
Remove the card and insert it again. Sometimes the SD card won’t mount properly if you put it into the slot too slowly. If the card still won't mount, you may need to reformat your SD card.
When I try to write content to the card, I get a 'cannot be modified' message. How can I fix this?
This message appears when you're trying to edit data on an SD card that’s locked. You need to use the lock slider to unlock the card before you can edit the data.
To eject the card, drag the icon that represents the card to the Bin. After the icon has disappeared from the desktop, you can remove the card from the computer. Adjust the lock slider tab to unlock the card, then reinsert the card into the slot. See the manufacturer’s instructions for the location of the slider tab.
Can I use Disc Utility to reformat an SD card?
You can use Disc Utility to partition and format an SD device as FAT32 (using the MS-DOS FAT setting) or Mac OS Extended. The Mac OS Extended format can only be used on Macintosh systems. Non-Apple systems won’t recognise cards formatted to Mac OS Extended.
You may have to format a card that’s larger than 32 GB 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. Formatting a card permanently deletes all of its files. Before continuing, make sure you have a backup of any files that you want to keep on the SD card.
