Before transferring files, you must ensure the drive is formatted correctly for your planned usage.

If your drive is currently read-only, you have two primary options: reformat it or use driver software.

| Problem | Solution | |---------|----------| | Drive not showing on desktop | Go to Finder > Preferences > General > Show External Disks. | | Still can’t write after formatting | Drive may be formatted as NTFS. Re-check in Disk Utility. | | Drive works but disconnects | Try a different cable or a powered USB hub. MacBooks often under-power portable drives. | | “Seagate Toolkit” software useless on Mac | Uninstall it. It’s mostly for Windows RGB control and backup scheduling. |

If your Mac only has USB-C ports and your Seagate drive came with a USB-A cable, you will need a USB-C to USB-A adapter or a dedicated USB-C to Micro-B cable.

Now that your drive is formatted, using it is as simple as dragging and dropping.
