Whether you are a creative professional handling 4K video or a home user looking to back up precious family photos, the Samsung Portable SSD T7 is one of the fastest and most reliable storage solutions available today. However, getting a new drive to play nice with macOS can sometimes feel a bit technical.

If you're wondering how to use Samsung portable SSD T7 on Mac effectively—from the initial unboxing to fixing the "Read-Only" NTFS blues—you've come to the right place. In this guide, we'll walk you through everything in plain English.
Unboxing Samsung T7 and Physical Connection
Before we dive into the software, let's ensure the physical connection is solid. The Samsung T7 typically comes with two cables:
- USB-C to USB-C: Use this for modern Macs (MacBook Pro/Air with M1, M2, or M3 chips).
- USB-C to USB-A: Use this for older Macs with the classic rectangular USB ports.
📌 Pro Tip: For the fastest data transfer speeds, always connect your T7 directly to your Mac's Thunderbolt or USB-C port rather than through a cheap USB hub.
Formatting the Samsung T7 for macOS
The Samsung T7 comes pre-formatted in exFAT. While exFAT works on both Windows and Mac, it isn't always the most stable for Mac-only users. If you plan to use the drive exclusively with Apple devices, formatting it to APFS (Apple File System) is highly recommended for better speed and reliability.
Steps to Format your T7:
- Connect your SSD to your Mac.
- Open Disk Utility (Press Command + Space and type "Disk Utility").
- Select the Samsung SSD T7 from the left sidebar.
- Click the Erase button at the top.
- Name: Give your drive a name (e.g., "My T7 SSD").
- Format: Choose APFS (for macOS High Sierra or later) or Mac OS Extended (Journaled) for older systems.
- Scheme: Choose GUID Partition Map.
- Click Erase.
🚨 Warning: This will wipe all data currently on the SSD. Back up your files first!

Use Samsung T7 with NTFS on Mac (No Formatting Required)
Many users find that their Samsung T7 is in NTFS format because they previously used it on a Windows PC. On a Mac, NTFS drives are "Read-Only"—meaning you can see your files, but you can't add new ones or delete anything.
If you don't want to format the drive (which would delete your Windows files), you can use a tool like Donemax NTFS for Mac.
Why use a dedicated NTFS driver?
- Write Access: Instantly gain the ability to copy, move, and delete files on NTFS.
- Speed: High-speed data transfer that matches native Mac speeds.
- Convenience: No need to move files back and forth to reformat the drive.
How to do it: Just install Donemax NTFS for Mac, connect your T7, and click Enable Writable button. Your drive will now behave just like a native Mac drive.

Troubleshooting: Samsung T7 Not Showing Up?
It can be frustrating when you plug in your SSD and nothing happens. If your Samsung portable SSD T7 is not recognized on Mac, try these quick fixes:
Check Finder Settings
Sometimes the drive is connected, but your Mac is hidden from showing it on the desktop.
- Open Finder.
- In the top menu, go to Settings (or Preferences).
- Under the General and Sidebar tabs, ensure "External disks" is checked.

Use Disk Utility to Mount
If it still doesn't show, open Disk Utility. If you see the Samsung T7 listed but it looks "greyed out," select it and click the Mount button at the top.
