(iv) Locked or Active File

Error-43 can also happen when the file you are trying to move is either in use or is locked. In these cases, you should stop using the file or unlock it before moving respectively. Also, sometimes you need permissions from administrator order in order to move a file.

How to Fix Mac Error Code 43

Like any other error, you need to fix this one too manually. To learn how to fix it, I  advise you to go through the stepwise guide to the methods I’m providing in order to apply them successfully. I’m presenting the 3 best methods available to fix Error-43 that will surely help you in one way or another.

1. Reset PRAM or NVRAM

PRAM or NVRAM stands for Parameter Random Access Memory or Non-volatile Random Access Memory respectively. It is a small amount of memory that Mac OS uses to save certain settings in order to access them quickly. Resetting PRAM or NVRAM works like charm for most of the systems. In order to do it, follow these steps:

Step-1: Firstly, shut down your Mac PC normally.

Step-2: While it shuts down, locate the Command, Option (alt), P and R keys.

Step-3: Turn on your PC again and press the Command + Option + P + R keys simultaneously before the grey startup screen shows up. That’s why I asked you to locate them beforehand.

Step-4: Hold these keys until you hear a startup sound three times and then finally release the keys.

This way you will reset the PRAM and it will further fix the Error-43 in your PC.

Note: In case you don’t hear the startup sound in Step-4, you should turn off your PC again and then follow the required steps. If the problem still persists, scroll down and try the next method.

2. Use Disk Utility

You should check the permission issue or directory corruption as the Error-43 is often related to corrupt or missing files. To do so, the Disk Utility tool comes into play. It is a built-in tool that deals with the drive related issues. You can try it by following these steps:

Step-1: Firstly, go to the Apple menu present at the top left part of your screen and click on Restart.

Step-2: After your PC restarts, press and hold the Command + R key simultaneously until you see the Apple logo.

Step-3: Now click on the Disk Utility option and then Continue.

Step-4: Go to the left side panel and select the disk you wish to repair (disk where the file you want to move is present). Then press the First-Aid button and continue with the Disk Utility check process.

Step-5: Disk Utility may give you several reports and you must take action accordingly.

Possible Reports

If it suggests that your disk is about to fail, immediately backup all your data and buy a new disk to replace it. While, if the Disk Utility tool is reporting that there are no issues or the issues are resolved then you can simply exit the tool. In this case, you can view the resolved issues by clicking on Show Details.


Disk Utility tool may also report “overlapped extent allocation” error. This says that there are several files occupying the same spot on your system. One of them might be corrupt, you should locate it in the DamagedFiles folder and repair or delete it.
One more possible outcome is, “The underlying task reported failure.” In this case, try running the First Aid tool again and if the problem still persists, backup your data and format the disk.

This might have solved your problem and you can comfortably delete files now. If the error is still there, scroll down.

3. Delete Locked Files

If the locked files are the main cause for Error-43 in your Mac PC, this method will work out perfectly for you. In this way, you can delete them without unlocking them first. Follow these steps:

Step-1: Firstly turn on your system and then follow this path: Application-> Utilities-> Terminal.

Step-2: In the Terminal, type and execute the following command:
chflags -R nouchg .

Step-3: Now empty the Trash. You can do so by double-clicking the Trash icon, pressing Command + A key to mark all the files and then dragging the files you want to delete from Trash to Terminal.

Note: In case you are unable to see the Terminal window, arrange Finder window, so that you can see at least a part of Terminal window. Once done, press Return key on the Terminal and then empty the Trash.

Done. By doing this, you have deleted the locked files creating conflict and fixed Error code 43.
