If you are still getting the problem and doing something like copying files, transferring to the external disk, etc, then you should try using a different port. Sometimes, the port can also be the reason why you might be getting the issue. So, you should try using it in a different port and check whether the problem gets resolved or not.

Try a Different Disk

If you’re experiencing issues when trying to access or use a disk (whether it’s an external hard drive, USB drive, or even a disk image), switching to a different disk can help determine if the problem is with the original disk or your Mac’s ability to interact with disks in general.

  • Safely Eject the Original Disk: Click on the eject icon next to the disk’s name in the Finder sidebar, or drag the disk icon to the Trash (which changes to an eject icon).
  • Connect a Different Disk: Plug in another external hard drive, USB drive, or mount a different disk image. Ensure this disk is known to work correctly on other systems or has been functioning properly in the past.
  • Attempt Access or Usage: Try to perform the same actions that were causing errors with the original disk. This could include opening files, copying data, or using applications stored on the disk.
  • Evaluate the Outcome: If you can successfully use the second disk without issues, the problem likely lies with the original disk. However, if the same or similar errors occur, the issue might be related to your Mac’s system software or hardware.

Change The Cable

The users can try using different cables if they are still facing the issue. There is a chance that the problem is occurring because the USB cable that you are using is not compatible or there are some problems with it.

Update macOS Software

Update macOS Software

If you have not updated your Mac for a long time, then it might be the reason you are facing the issue. There are a lot of users who keep postponing the updates, so they keep getting issues because of the old bugs. So it will be good for you to go to Settings and Check For The Updates on your Mac from there. If there are any new updates available, then you should download it and check whether the issue has been resolved or not.

Try a Different File with the Original Disk

If you are facing the Error Code 100006 issue with some specific file, then there is a chance that the file is corrupted. In case the files are corrupted, then the system won’t be able to read them, and it will not be able to transfer to the desired location. You should make sure that the file that you are trying to send is not corrupted. If the file is corrupted, then you will be going to face a problem.

  • Identify a Problematic File: Note which file is causing errors, such as failing to open, showing corruption signs, or triggering system errors.
  • Select a Different File: Choose another file on the same disk, preferably one that is similar in type or size to the problematic file, but known to be without issues previously.
  • Attempt to Open or Use the New File: Try to open, copy, or interact with the new file in the same way you did with the problematic file.
  • Analyze the Results: If the new file works without issues, the problem may be with the original file itself (e.g., corruption, incompatible format). If the error persists, the issue may be more systemic, related to the disk or the Mac.

Check File Permissions 

You will get the Error Code 100006 on your Mac even if the permissions are not given for the files properly. Yes, if the permission is not set for Everyone for the Read & Write, then you will be going to face the issue. So it will be good for you to check the permission of the file on your Mac. Incorrect file permissions can prevent files from being accessed, modified, or executed as intended, leading to errors.

  • Locate the Problematic File or Folder: Using Finder, navigate to the file or folder you’re having issues with.
  • Get Info: Right-click (or Control-click) on the file or folder and select “Get Info” from the context menu.
  • Expand the ‘Sharing & Permissions’ Section: Scroll down to the bottom of the Info window to find the ‘Sharing & Permissions’ section. You may need to click the triangle icon next to it to expand this section.
  • Check Permissions: Look at the permissions listed for your user account. You should have ‘Read & Write’ access for files you need to modify or delete. If not, proceed to adjust permissions.
  • Adjust Permissions if Necessary: Click the lock icon at the bottom right of the window to make changes (you may need to enter your administrator password). Click the ‘+’ button to add your user account if it’s not listed, or select your user and choose ‘Read & Write’ from the dropdown menu next to your name.
  • Apply Changes: After adjusting permissions, close the Get Info window. Attempt to access or modify the file again to see if the issue has been resolved.

Reboot Your Mac in the Safe Mode

Safe Mode is a diagnostic tool built into macOS that starts your Mac in a basic state, using a minimal set of system extensions, preferences, and fonts. It can be helpful for troubleshooting issues, including performance problems and software conflicts. The process for entering Safe Mode differs between Intel-based Macs and those with Apple Silicon.

For Intel-based Macs:

Intel-based Macs rely on a traditional startup process that involves pressing a key combination during boot-up.

  1. Shut Down Your Mac: If your Mac is on, shut it down by going to the Apple menu and selecting “Shut Down.”
  2. Start in Safe Mode: Press the power button to turn on your Mac, then immediately press and hold the Shift key. The Apple logo will appear on your screen.
  3. Release the Shift Key: Once you see the login window, you can release the Shift key. Note that you might see the login window twice; if so, log in as usual both times.
  4. Verify Safe Mode: To confirm you’re in Safe Mode, open the Apple menu and select “About This Mac,” then click “System Report.” Under “Software,” you should see “Boot Mode” listed as “Safe.”

For Apple Silicon-based Macs:

Macs with Apple Silicon, including the M1 chip, use a different process that involves using the startup options to enter Safe Mode.

  1. Shut Down Your Mac: Ensure your Mac is completely shut down by selecting “Shut Down” from the Apple menu.
  2. Enter the Startup Options Screen: Press and hold the power button on your Mac until you see the startup options window, which shows your available startup disks and a gear icon labeled “Options.”
  3. Select Your Startup Disk: Click the startup disk you wish to use; it’s usually named “Macintosh HD” unless you’ve renamed it.
  4. Press and Hold the Shift Key: With the startup disk selected, press and hold the Shift key, then click “Continue in Safe Mode.” You may release the Shift key after clicking.
  5. Log in to Your Mac (if necessary): If prompted, log in to your Mac. Your Mac will now finish booting up in Safe Mode.
  6. Verify Safe Mode: Once logged in, you can verify you’re in Safe Mode by checking the upper-right corner of the login screen, which should indicate Safe Mode, or by using the “System Report” under “About This Mac” as described for Intel-based Macs.

Exiting Safe Mode

To exit Safe Mode, simply restart your Mac without holding any keys (Intel-based) or through the normal boot process without holding the Shift key (Apple Silicon-based). Your Mac will start up normally, exiting Safe Mode.

Using Safe Mode can help you determine if issues you’re experiencing are related to specific software or system extensions by running macOS in a minimal state. If problems don’t recur in Safe Mode, it’s likely that software or extensions loaded during normal startup are causing the issue.

A lot of users were trying to find ways to fix the Error Code 100006. We have listed the ways through which you will be able to fix this issue on your Mac. We hope this guide has helped you in resolving the issue.
