Mac setup starts with a USB-C port that can supply 15W and with physical-device visibility in Disk Utility.
Quick answer
Fast answer for X Vault on Mac
Once the drive is detected, filesystem choice depends on Mac-only versus Mac-and-Windows use.

External-storage checklist
Four checks before buying or troubleshooting
Verify the exact family
FireCuda X Vault, FireCuda Gaming SSD, One Touch Hub and Expansion Desktop are separate products. Do not let similar Seagate branding collapse them into one listing.
Match the capacity
An 8TB X Vault is not interchangeable with the 20TB model, and the Gaming SSD has its own 500GB, 1TB and 2TB identities.
Check port capability
USB-C describes a connector, not guaranteed power or speed. X Vault needs a host port that can deliver at least 15W; Gaming SSD needs USB 3.2 Gen 2x2 for its 20Gbps link tier.
Protect the data first
A format, erase or repair step can destroy recoverable data. Diagnose power, visibility, cable and link state before destructive changes.
Start with the Mac port, not formatting
A Mac-specific X Vault check should account for starting with the Mac port, not formatting. Seagate positions X Vault for Windows and macOS use. First prove that Disk Utility can see the physical device and that the connected port satisfies the power requirement. A Mac connection still has to satisfy the drive’s minimum 15W USB-C power requirement. Once detection is stable, choose a filesystem according to whether Windows sharing is required. Disk Utility distinguishes a detected physical device from an unmounted or incompatible volume. Cross-platform portability and Mac-native features pull that choice in different directions. Filesystem choice should follow whether the drive is Mac-only or needs read/write sharing with Windows. An erase should occur only when existing data is protected and the user intentionally wants a new volume layout.
