My Mac doesn’t recognize my SanDisk Ultra 32GB SD card installed with Raspbian. I have installed Raspbian in a Micro SD card following the instructions and Raspbian works well in my Raspberry 3. However, now I want to copy data from my MacBook to the card, but I found Disk Utility doesn’t recognize the SD card.
Raspbian is a Debian-based operating system for Raspberry Pi computers. The file system used by Raspbian (usually ext4) is not natively supported by macOS. To make a Mac recognize the SD card installed with Raspbian, you should use an additional software - Raspberry Pi Imager. It is the official tool of Raspberry Pi.
The file systems that macOS fully supports (read-write) are APFS, Mac OS Extended, exFAT, and MS-DOS (FAT). macOS doesn’t support Ext4, Ext3, XFS, and other file systems that are designed for other operating systems.
It is worth mentioning that macOS supports reading the Windows default file system NTFS. If you want your NTFS drives for cross-platform use, you can use NTFS for Mac software like iBoysoft NTFS for Mac to fully read and write to them on Mac devices. Need it? Download iBoysoft NTFS for Mac here.
