When you format your SDCard using your Fujifilm camera, it uses NTFS. Sometimes macOS can automatically mount the SDCard when inserted, but sometimes it doesn't.
This has been tested using the following devices:
- Fujifilm X-T3 on Ver.5.10 firmware
- macOS 14.2.1 Sonoma on M2 Max Macbook Pro
- SanDisk Extreme Pro 64GB
