A true "driver" for Seagate on Mac doesn’t exist for standard use. You only need NTFS software or the optional Toolkit. If your drive isn’t working, reformatting or power management is likely the real fix.

No. macOS has built-in support for reading/writing Seagate drives formatted as exFAT or FAT32 . However: If your drive is formatted as NTFS (Windows default), a Mac can only read it unless you install special software (not a traditional driver, but a file system add-on).
