Sometimes error code 43, associated with file transfer issues on Mac devices, will pop up. This error code may occur when you delete a file, move it to the Trash, move files from one folder to another, or transfer files from or to a USB drive. It can also be related to incompatible file name characters. The best way to avoid error 43 would be to rename your files and avoid symbols in general.

The same error will occur if the file has not been downloaded fully. The most common cause of partial download is the loss of internet connection. Another reason can be an incomplete source file. There is also a chance of a timeout. It can also be the cause of the file being used by one or more system applications. Open Terminal and type "loss | green -i [files name]". This will show a list of all open files and the processes that opened them.

Bellow, you'll find troubleshooting steps that will help you eliminate Mac error code 43.

Disk Utility Check

Your Mac's built-in Disk Utility is a great tool that will spot missing or corrupt files triggered by an HDD/SSD problem.

1. After your Mac restarts, go to Finder and click on Applications.
2. Then find and select "Disk Utility".

3. Select the disk (disk where the file you want to move is present) you wish to repair.
4. Press "First-Aid".

5. Click on "Run" and then on "Continue".

If the reports show that your disk is about to fail, back up your files and replace your hard disk with a new one.

Click on Run. If the Disk Utility tool shows no problems with your drive or that the existing issue has been solved, you can exit the tool.

If the "overlapped extent allocation" appears and states that several files occupy the same spot on your drive, one of those files is probably corrupt. You will have to locate it in the Damaged Files folder.

The worst-case scenario is that you won't be able to check or repair your disk. Try re-running the First Aid tool if the "The underlying task reported failure" error message appears. If the error message continues to appear, backup your data and format your disk.
