1. Connect the drive via USB, Thunderbolt, or other supported ports.
  2. Open Finder.
  3. Look in the Sidebar under “Locations” — your drive should appear there.
  4. If it doesn’t show up:
    • Go to Finder > Settings > Sidebar and make sure “External disks” is checked.
    • Or open Disk Utility (search via Spotlight with CMD + Space).
    • Select the drive and click Mount if it’s not already mounted.
