How to Fix Error Code -43 on Mac?

Since there are many reasons behind the error code 43 issue, we will cover helpful solutions to various cases. Please troubleshoot your problem following the guide below.

If you are transferring files named on a Windows PC to Mac, the Mac error code 43 may occur when the file name doesn't suit macOS or has more than 30 characters.

2. Make sure the file in want is fully downloaded. If not, wait until it's done.

To discover what apps or processes are interacting with a file, you need to open Terminal > enter the command lsof and press the Space bar once > select the file in Finder > drag and drop the file to Terminal window > press Enter.

On the Terminal window, you will see apps that are active with the file. Close these apps, then try to manage the file again and see whether the Macintosh error code 43 shows up.

Solution 1: Force Quit Finder

Another potential fix for Macintosh error code 43 is to check and repair Mac disk with Disk Utility First Aid. To do this, you need to launch Disk Utility from Recovery Mode, select the drive with the files you want to move or delete, then click First Aid.

It may report the "Overlapped Extent Allocation" error, signaling that more than one file is using the same portion of the selected hard drive and there is at least one corrupt file.

You can also get rid of those corrupt files by locating them in the DamagedFiles folder and deleting them. You can also make a second scan to meet the success. After First Aid automatically repairs your drive, you should be able to move and delete files as you like. This solution can help you fix Mac error code 41 as well.
