macOS can read NTFS drives by default but generally cannot write to them without additional software.
File Size Limits
Many people choose exFAT because of its support for large files.
exFAT
Supports:
- Extremely large files
- Very large partitions
NTFS
Also supports:
- Very large files
- Massive storage volumes
For modern users, both file systems easily handle large videos, backups, and games.
Security Features
