That is why we are devoting a whole section to explain this error in as much detail as possible.

Now that we have said all of that, let’s now talk about error 43 in detail.

As we have said the error happens most often in El Capitan and OS X 10.2. If this error has happened to you, you will have most probably noticed that it is often displayed when you try to move files around.

This error happens particularly when you are trying to move stuff into the trash can but not only then I think it also happens if you’re trying to move files to a different directory. The full error message displaying is something like this: “The operation cannot be completed because one or more required items cannot be found (Error code 43)”.

We are aware that if you are reading this article you are probably already aware of this. But it is always worth making entirely sure that you are reading something about that right error and not something else.

If you are now sure that we are talking about the error you are concerned about we can move on to the specific possible causes behind it.

You may be surprised by what could be behind error 43. It is very often the case that users cause this error themselves, albeit of course inadvertently.

“What it is now is basically I’ll sit on my computer; I basically kind of play the computer as an instrument, I guess you could say. I guess I play the Mac.” – Flume

For example, this error could be caused by the mere fact of a user-chosen one or more so-called illegal characters in their file name.

Here are the characters considered illegal for that purpose: @ ! # % ^ $ *. You shoot, therefore, always avoid using any of those characters when naming your files. So, this error could happen when you’re trying to move a file that uses one or any of these illegal characters to the trashcan or elsewhere in the directory. In that case, the solution would be very easy. All you need to do would be to rename the file or, at least, remove the illegal characters you have used.

Another possible cause of error 43 could be that there is no shared point for the file in question. By this, we mean that the finder cannot access the file that you are trying to move.

If the problem is not caused by either of those situations, it may very well be an issue with your hard disk. Otherwise, it could be that you installed the internal OS problem or that there are issues that relate to permissions for the fire that you are trying to move. In the latter case, it could be that the file that you are trying to move needs to be accessed by the administrator.

There could be some other reasons, such as needing more space on the computer, and so on. Thankfully, despite the fact that this problem could be caused by a variety of very different problems, it is not that challenging to solve it.

One very common reason for this error is simply caused by the fact that the far you’re trying to move has not been fully downloaded. It is important that you make sure the file is fully downloaded before you attempt to move it to the trashcan or anywhere else. Similarly, if you are using the file you will not be able to move it and you may get the error. In that case, the solution would be really easy, just stop using the file.

You should always, in any case, check whether the files you are trying to if locked (and, if it is, you should unlock it before you attempt to move it). You might also sometimes need permission from the administrator’s order to move or delete a file. Finally, you will need to check whether the file you were trying to move is being used or any other task has not been completed yet.

Fix For Error 43

First, a word of warning for those who might have skipped the previous section and come directly to this one.

In the previous section, we have gone through the possible causes but we have also already hinted at some very easy fixes. So if you do not find what you are looking for in this section after you have read it through, we would suggest you go back to the previous section for more hints.

If you have gone through all the causes we have discussed and still, the problem persists, then you should reset the PRAM (Parameter Random Access Memory) on your Mac computer. Doing this I would require you to follow these simple steps:

  1. The first thing you will need to do is to make sure that you shut down your Mac computer as you normally do.
  2. Once your Mac computer is fully shut down, you should take your time to locate the command key, the option key (alt), P, and R keys. You will need these keys for the next steps.
  3. Then you would need to return your Mac computer back on.
  4. Once your Mac computer is fully turned on again you should press those keys and hold them down as soon as possible. You need to do this before the gray screen displays, this is why it is so important that you have previously located the keys. If it doesn’t work out the first time, just shut down the computer and try again, and be sure that you are ready.
  5. Hold down the command, option, P, R keys for a while. There is no fixed amount of time, you will need to do this until you hear the sound that means the computer starting up three times.
  6. Once you have heard that sound for three times, release those for keys simultaneously.

Following these steps, you will be able to reset the PRAM (Parameter Random Access Memory). This may not be what is causing the problem, however. It may be that you’re trying to delete a file that is locked. The easy solution to this problem would be, as we suggested the previous section, to unlock it. However, we are aware that sometimes this is not possible. Luckily, there is a way for users to delete log files without unlocking them first.

All you need to do would be to follow these simple steps:

  1. Start your Mac computer.
  2. Go to your applications folder.
  3. Then head over to utilities.
  4. Once in the utilities folder locate terminal and launch it.
  5. Then you will need to type in the following command: chflags -R nouchg and make sure that you leave a space after.
  6. Then you will need to double-click on the trashcan icon. This action will display the contents of the trashcan.
  7. Next, you will need to click on the command A key.
  8. Then simply drag the locked files that you are trying to delete from the trash can to The terminal window.
  9. Once you have done this click on the return key.
  10. Finally, empty the trashcan.

  1. hello,

    you said probably won’t fix it but it did, the command (option key (alt) +P +R) while starting the Mac worked for me without further steps. I didn’t hear any sounds 3x times, or whatever. Just one sound as normal at the start. I logged myself in, and tried to delete the files I wanted to, and it worked. So thank you anyway.

  2. This error is still happening in higher versions of the Mac OS. I have 10.13.4. I was trying to delete files off a thumb drive and got the error.
    My files were purchased, downloaded files for my family and automatically had the # symbol in the file name (#63 Up In the Air Adventures in Odyssey). I tried deleting the symbol but it did not help. I just happened to go to the Disk Utility and ran First Aid on the drive. I went back and was able to delete the files.

  3. I had a more detailed comment but it got wiped out while trying to post. Retyping:
    I have Mac High Sierra and Error 43 still happens.
    Basically, I tried to delete files off a thumb drive that had # in the file name. I removed the # but I still couldn’t delete. Went to Disk Utility, ran First Aid on the drive and I was able to delete.
