Are you frustrated because you can’t copy files from your Mac to an external hard drive? You’re not alone. Many Mac users have faced this issue, and it’s more common than you think. In this article, we’ll dive into the possible reasons why you’re stuck in this limbo and provide you with solutions to get your files transferring smoothly again.
The Mysterious Case of the Uncooperative External Hard Drive
Before we begin troubleshooting, let’s take a step back and understand how external hard drives work with Macs. When you connect an external hard drive to your Mac, it should be recognized by the operating system, and you should be able to read and write files to it. However, sometimes things don’t go as planned, and you’re left wondering why your files won’t copy.
Is It a Mac Problem or an External Hard Drive Problem?
The first step in resolving this issue is to determine whether the problem lies with your Mac or the external hard drive. Try connecting the external hard drive to another Mac or a different computer to see if the issue persists. If the problem follows the external hard drive, then it’s likely that the issue is with the drive itself. However, if the problem only occurs when you connect the drive to your Mac, then it’s probably a Mac-related issue.
Possible Reasons Why You Can’t Copy Files
Now that we’ve narrowed down the problem, let’s explore some possible reasons why you can’t copy files from your Mac to an external hard drive.
File System Incompatibility
One of the most common reasons for this issue is file system incompatibility. Macs use the APFS (Apple File System) or HFS+ (Hierarchical File System Plus) file systems, while external hard drives often use NTFS (New Technology File System) or FAT32. If your external hard drive is formatted in NTFS, you won’t be able to write files to it from your Mac, as Macs don’t support writing to NTFS drives out of the box.
To overcome this, you can either reformat the external hard drive in a compatible file system like APFS or HFS+, or use a third-party NTFS driver that allows you to write to NTFS drives from your Mac.
Permissions Issues
Another reason you might not be able to copy files is due to permissions issues. If the external hard drive has been used on a Windows machine previously, it may have permissions set that restrict access from a Mac. To resolve this, you’ll need to change the permissions on the external hard drive to allow your Mac to write to it.
Connection Issues
Sometimes, the issue can be as simple as a loose connection or a faulty cable. Make sure that the external hard drive is properly connected to your Mac, and try using a different cable or port to rule out any connection issues.
Disk Utility Issues
Disk Utility is a built-in Mac tool that helps you manage and repair disk issues. However, sometimes Disk Utility can get stuck or fail to recognize the external hard drive, preventing you from copying files. Try restarting Disk Utility or using the command line version of the tool to see if that resolves the issue.
Space Issues
If your external hard drive is full or running low on space, you won’t be able to copy files to it. Make sure you have enough free space on the drive to accommodate the files you want to transfer.
Troubleshooting Steps to Get Your Files Transferring Again
Now that we’ve explored the possible reasons why you can’t copy files, let’s walk through some troubleshooting steps to get your files transferring again.
Step 1: Restart Your Mac and External Hard Drive
Sometimes, a simple reboot can resolve the issue. Restart your Mac and external hard drive, then try copying the files again.
Step 2: Check the External Hard Drive’s Connection
Ensure that the external hard drive is properly connected to your Mac, and try using a different cable or port to rule out any connection issues.
Step 3: Check the External Hard Drive’s File System
If the external hard drive is formatted in NTFS, try reformatting it in a compatible file system like APFS or HFS+. Alternatively, use a third-party NTFS driver to allow writing to NTFS drives from your Mac.
Step 4: Change Permissions on the External Hard Drive
If you suspect permissions issues, try changing the permissions on the external hard drive to allow your Mac to write to it.
Step 5: Use Disk Utility to Repair the External Hard Drive
Try using Disk Utility to repair the external hard drive and resolve any disk issues that may be preventing you from copying files.
Step 6: Free Up Space on the External Hard Drive
If the external hard drive is full or running low on space, try freeing up space by deleting unnecessary files or expanding the drive’s capacity.
Additional Tips to Prevent Future Issues
To prevent future issues with copying files from your Mac to an external hard drive, follow these additional tips:
| Tips | Description |
|---|---|
| Use a compatible file system | Format your external hard drive in a compatible file system like APFS or HFS+ to ensure seamless file transfer. |

Why can’t I copy files from my Mac to an external hard drive?
This issue is often caused by a compatibility problem between the file system used by your Mac and the external hard drive. Modern Macs use the APFS (Apple File System) file system, while many external hard drives use NTFS (New Technology File System) or HFS+ (Hierarchical File System Plus). These file systems are not natively compatible, which can prevent files from being copied successfully.
To resolve this issue, you can try reformatting the external hard drive to use APFS or ExFAT, which is compatible with both Mac and PC. Alternatively, you can use a third-party software that enables your Mac to read and write to NTFS partitions.
What is APFS and why does it cause compatibility issues?
APFS is a file system developed by Apple, introduced in 2017 with macOS High Sierra. It is designed to provide improved performance, security, and reliability. However, APFS is not backward compatible with older file systems, which can cause issues when trying to copy files to external hard drives that use older file systems.
Despite its benefits, APFS can be a barrier to compatibility with external devices. To mitigate this, you can use a third-party software or reformat the external hard drive to use a compatible file system. It’s also important to ensure that your external hard drive is compatible with your Mac’s operating system.
What is the difference between NTFS and HFS+?
NTFS is a file system developed by Microsoft, used in Windows operating systems. It is widely supported by external hard drives, but not natively compatible with Macs. HFS+, on the other hand, is an older file system developed by Apple, which was replaced by APFS in 2017. While HFS+ is still supported by Macs, it is not as efficient as APFS and can cause compatibility issues with newer external hard drives.
When choosing an external hard drive, consider one that uses ExFAT, which is compatible with both Mac and PC. Alternatively, reformat the external hard drive to use APFS or use a third-party software to enable compatibility.
Can I use a third-party software to enable compatibility?
Yes, there are several third-party software options available that enable your Mac to read and write to NTFS partitions. Some popular options include Parallels Transporter, Tuxera NTFS, and Mounty. These software solutions can provide a seamless experience when working with external hard drives.
Before choosing a software, ensure it is compatible with your Mac’s operating system and the file system used by your external hard drive. It’s also essential to follow the software’s instructions carefully to avoid any potential data loss or corruption.
Why do I need to reformat my external hard drive?
Reformatting your external hard drive can resolve compatibility issues by changing the file system to one that is compatible with your Mac. This process erases all data on the drive, so it’s essential to back up any important files before proceeding.
When reformatting, choose a file system that is compatible with your Mac, such as APFS or ExFAT. Be cautious when reformatting, as it will erase all data on the drive. If you’re unsure about the process, consider consulting the external hard drive’s user manual or contacting the manufacturer’s support team.
How do I back up my files before reformatting?
Before reformatting your external hard drive, back up any important files to a cloud storage service, such as iCloud, Google Drive, or Dropbox, or to another external hard drive. This ensures that your files are safe and can be restored after the reformatting process.
Use the Finder or the Disk Utility app to back up your files. You can also use Time Machine, a built-in backup feature in macOS, to create a backup of your files. Make sure to verify the integrity of your backups before proceeding with the reformatting process.
Are there any other solutions to resolve compatibility issues?
Yes, there are other solutions available to resolve compatibility issues. One option is to use a cloud storage service, which allows you to access your files from any device, without the need for an external hard drive. Another option is to use a NAS (Network-Attached Storage) device, which can be configured to use a compatible file system.
These solutions can provide a convenient and compatible way to store and access your files. However, they may require a subscription or an initial investment in the NAS device. Consider your specific needs and preferences when choosing a solution.
