[Quick Guide] How to Format SD Card to NTFS on Mac

Super User: How to format SD card to NTFS on Mac?

A discussion on Superuser.com brings attention to a situation that many Mac users may find familiar. In the post, a user explained that they wanted to reformat a 16 GB SD card to NTFS in order to transfer files larger than 4 GB between different computers. This need is quite common, especially when handling videos, photos, or other large data files. However, when the user attempted to format the SD card on a Mac, the system only offered FAT-based formats, with no option to select NTFS.

This behavior is not a fault with the SD card itself, but rather a limitation of macOS. By default, macOS can read NTFS drives but does not fully support writing or formatting them. Because of this restriction, users may be unable to format an SD card to NTFS, delete existing files, or make other changes using built-in Mac tools. Situations like this often cause confusion, particularly for users who regularly switch between macOS and Windows.

This real case clearly reflects a broader issue many people face when using SD cards across different platforms. In the following sections, we will explain why this happens and walk you through reliable ways to format an SD card to NTFS on a Mac smoothly and safely.

How to format SD card to NTFS on Mac?

On macOS, Disk Utility does not provide an option to format an SD card to NTFS, as Apple does not natively support creating or writing to NTFS file systems. Instead, Disk Utility only supports formats such as APFS, Mac OS Extended, FAT32, and exFAT. For this reason, many users choose to format the SD card to NTFS on a Windows PC, where NTFS is fully supported.

Afterward, the card can be read on a Mac, but writing is restricted. To conveniently add, delete, or manage files on the NTFS-formatted SD card, a reliable solution such as PartitionAssistant NTFS for Mac is required.

FAQs

🗨️ Why can't Mac write to NTFS?
