MacOS -36: Fixing MacOS File Copy Errors

The -36 error on macOS typically occurs when attempting to copy, move, or back up files.

This error is often related to file system issues, such as hidden or invalid file attributes, or incompatibilities between file systems on different devices.

To fix the error, start by checking for any hidden files causing the issue.

In Finder, press Command + Shift + . to reveal hidden files, and look for any .DS_Store or .AppleDouble files that may be interfering.

Delete any such files and try the copy operation again.

If the error occurs when transferring files to or from an external drive, ensure the drive is formatted in a compatible file system (like exFAT or FAT32).

You can reformat the drive using Disk Utility if necessary.

Another solution is to try copying files via the Terminal.

Open Terminal, navigate to the source directory using the cd command, and use the cp command to copy the file.

If the problem persists, running First Aid in Disk Utility can help check and repair any file system issues.
