Before we start: macOS natively supports reading NTFS drives on M5 Apple Silicon Macs, but write access is disabled by default. The easiest and safest way to get full read and write access without formatting or losing data is to use Donemax NTFS for Mac. Alternatively, you can reformat the drive to exFAT for cross-platform compatibility or use cloud storage as a bridge.

Did you just upgrade to a powerful new Apple M5 Mac and plug in your Windows-formatted external hard drive, only to realize you cannot copy, edit, or delete any files? If so, you are not alone. By default, macOS allows you to open and view files on Microsoft NTFS formatted drives, but it blocks you from saving new files or making changes.
When you try to copy a document, edit a photo, or drag a video onto an NTFS drive on your M5 Mac, you will notice that the drive is set to 'Read-Only'. This compatibility gap between Windows and macOS can be frustrating, especially when working with large hard drives or transferring data between different systems.

The good news is that enabling full read write NTFS external hard drive M5 Mac support is simple when you use the right approach. In this comprehensive guide, we will break down 4 reliable methods—ranging from seamless one-click software like Donemax NTFS for Mac to built-in formatting options—so you can choose the best solution for your needs.
Why Can't Your M5 Mac Write to an NTFS Drive?
To understand why your M5 Mac restricts you from modifying files on an NTFS external hard drive, it helps to understand how file systems work:
- Microsoft's Proprietary Standard: NTFS (New Technology File System) is Microsoft's proprietary file system created specifically for Windows operating systems.
- Apple's Native Restriction: Apple includes built-in read support for NTFS in macOS so users can view files created on Windows PCs. However, native write support is omitted due to licensing boundaries and stability risks.
- Apple Silicon Architecture (M5 Security): Modern M-series processors (including M1, M2, M3, M4, and the latest M5 chips) run under strict System Integrity Protection (SIP) and secure architecture. Unofficial Terminal workarounds that used to work on old Intel Macs are blocked or highly unstable on Apple Silicon M5 chips.

Step 2: Connect your NTFS external hard drive or USB drive into your M5 Mac.

Method 2: Reformat the Drive for Mac Use
If your external hard drive is brand new, empty, or contains files you have already backed up elsewhere, you can reformat the drive to exFAT. The exFAT file system is natively supported with full read and write permissions on both Windows and macOS.
If you plan to use your external hard drive exclusively with your M5 Mac and never need to plug it into a Windows PC, formatting it to Apple File System (APFS) offers the highest performance, snapshots, and encryption features.
📍 Important Warning: Formatting erases ALL existing data on the drive permanently. Always back up your files before proceeding with this method!
Step-by-Step Instructions:
Step 1: Plug your external hard drive into your M5 Mac.
Step 2: Open Finder > Applications > Utilities, and double-click 'Disk Utility' (or search for it via Spotlight with Cmd + Space).
Step 3: In Disk Utility, click 'View' in the top-left corner and select 'Show All Devices'.
Step 4: Select the top-level external hard drive from the left sidebar and click the 'Erase' button in the toolbar.
Step 5: Set a name for your drive, choose 'exFAT' or 'APFS' as the Format, and select 'GUID Partition Map' as the Scheme.
Step 6: Click 'Erase' to confirm. Once finished, your drive will work on M5 Mac with full read and write access.

Method 3: Use Cloud Storage Services as a File Bridge
If you only need to modify or transfer a few small documents from an NTFS drive occasionally and do not want to install software or reformat the drive, you can use a cloud bridge service like Google Drive, OneDrive, or Dropbox.
Step-by-Step Instructions:
Step 1: Plug the NTFS drive into your M5 Mac and open the files in read-only mode.
Step 2: Upload the required files from your NTFS drive to your Google Drive, OneDrive, or iCloud account.
Step 3: Edit the files on your Mac or sync them back down to your local storage.
Step 4: If you need the modified file back on the NTFS drive, connect the drive to a Windows PC and download the updated file from your cloud account.
