What are the causes of the Mac error 100060?

Below we have mentioned a few possible causes that might be causing the Mac error 100060.

  • Using outdated or incompatible software.
  • Corrupted files or directories.
  • Deleted a necessary file.

How to fix the issue?

If you encounter the error code 100060 on Mac, we have explained a few ways to help you fix the issue.

Transfer a small file before transferring large files

Users who have experienced error code 100060 on Mac have discovered that they can successfully move their desired files by transferring a small text file or a single photo. Transferring a small file first is recommended if you haven’t attempted this method.

If that approach proves unsuccessful, an alternative solution is to divide the larger files into smaller segments, compress the file to reduce its size, and then attempt the transfer again.

Use an external USB adaptor

Mac error code 100060 commonly occurs during file transfers to SD or micro SD cards connected via the built-in SD card slot. However, a generic external USB-C adapter will likely circumvent this problem.

Update the macOS

If you have recently upgraded to macOS Big Sur and are encountering error code 100060, rest assured that you are not alone. The good news is that updating to macOS 12.1 has reportedly resolved the problem for several users. To check for any latest update available for your Mac, follow the below steps.

Step 1: Click on the Apple icon on the top-left of the toolbar then select System Settings

Step 2: Select General and then Software Update.

Step 3: If there is any update available then install it.

Boot in Safe Mode

If you encounter error code 100060 on your Mac, attempting to boot into Safe Mode can be helpful. Safe Mode is an effective troubleshooting technique by disabling third-party applications during startup, clearing system caches, and thoroughly examining the boot disk for potential errors.

To proceed, simply restart your Mac in Safe Mode and retry the file transfer to determine if the error persists. If the issue is resolved in Safe Mode, you can then restart your Mac normally and disable any login items that may be causing interference with the transfer process.

Disable Antivirus

There are situations where antivirus or security software, such as Norton Antivirus, can create complications during file transfers on Mac. This can arise from incompatibility with the updated operating system or activating blocking features like Norton Firewall Vulnerability Blocking or Vulnerability Protection.

If you have Norton 360 installed, it is plausible that the application is not operating optimally with macOS Big Sur, particularly when writing data to NAS drives. To fix this, you can try updating Norton to determine if the problem is resolved. If the issue persists, disabling Norton or any features that might be causing problems while file transfers on your Mac is advisable.

Delete file

Error code 100060 could be related to a problem with Finder and can be fixed by resetting its preferences.

Step 1: Click Go > Go to Folder at the top.

Step 2: Enter Library/Preferences and press Enter.

Step 3: Right-click and choose Move to Trash.

Step 4: Empty the Trash bin and then restart your Mac.

Use the Terminal to transfer files

If you are unable to perform file transfers using Finder, you have the option to use Terminal, which is a built-in command-line utility, to accomplish the task. This alternative proves particularly beneficial when faced with error code 100060, as it enables you to copy files from your Mac to an external device without encountering the error.

To copy a single file, follow the steps mentioned below.

Step 1: Open the Finder. Then go to Applications> Utilities folder.

Step 2: Click on Terminal.

Step 3: Enter the following command in the terminal and hit Enter.

cp filepath /Volumes/drivename and hit Enter

To copy a folder of files use the following command and hit Enter

cp -R folderpath /Volumes/drivename

Repair the external driver

It is possible that the external hard drive or SD card is encountering file system errors, which could be causing difficulties in file copying. Fortunately, you can use the First Aid feature to repair the drive and resolve the issue. To do that follow the steps below.

Step 1: Open the Finder. Then go to Applications> Utilities folder.

Step 2: Go to Disk Utility.

Step 3: Select the drive that you want to fix from the left side of the screen and then click on First Aid.

Step 4: Confirm the scan by selecting Run.

If First Aid detects errors it cannot fix, you may need to reformat the drive as a potential solution. So make a backup before trying this method.

Reinstall macOS

If none of the above methods works for you, the last option before concluding it a hardware problem is reinstalling macOS. The advantage is that you can perform the reinstallation without erasing the startup disk, ensuring that your data remains intact. Nevertheless, it is strongly advised to back up your Mac using Time Machine as a precautionary measure in case any complications arise during reinstallation.
