How to fix Error 36 on Mac?

How to fix issue, while Finder displaying Error 36 on Mac computers?

Mac computers are well known as stable, fast devices in terms of overall performance and content management. Many Mac computer users enjoy virtually flawless data management and rapid file transfers. Unfortunately, Finder error code 36 can sometimes appear - stating that an operation could not be completed, since files cannot be read/written to. This is a rare issue that can occur on computers running any version of the Mac operating system. Although this particular issue is uncommon, there are a number of solutions. Fortunately, this error is not generally related to hardware or software crashes.

In most cases, the problematic file (which cannot be read/written to) contains a dot-underline (._) extension. A common example of such a file is '.DS_Store'. These hidden files contain additional information, such as icon images and associated files. When these files are being transferred between a Windows compatible volume to Mac and vice versa, error 36 occurs. The most efficient solution is to use a built-in command line window and the dot_clean function, however, the reason for Finder's error 36 might sometimes be different - perhaps viruses, malware, corrupted files, or even junk files. In this article, we describe the most effective methods to solve this frustrating issue, regardless of the cause.

Use dot_clean via Terminal to solve error 36

In the most frequent cases, Finder error 36 problems are caused by attempts to transfer hidden system files such as .DS_Store and others, which contain the dot-underline extension within their names. As mentioned above, these files simply contain additional information and, therefore, no damage is done to the original file if you delete the hidden file. This is one of the best ways to solve error 36, however, there might be many such hidden files. Therefore, use the dot_clean command via Terminal, which cleans all hidden files within the selected directory. Launch the command line application via Spotlight by pressing the keyboard shortcut of Command and Spacebar. Then type Terminal and press return. When the application launches, type 'dot_clean', press Spacebar, and then drag-and-drop the folder being used to transfer files (and resulting in error 36). This way, Terminal will automatically generate the location of the problematic file/folder. Finally, press Return to execute.

Alternatively, drag-and-drop, or manually type the location of the entire Volume to clean it all. This is recommended if you encounter error 36 when attempting to backup the volume. Once the Terminal process finishes, try to move the same folder to check if error 36 has been resolved.

Check permissions and perform a Safe boot

Another common case resulting in occurrences of error 36 are mismatches in folder permissions and sharing options, and issues with external devices. Check permissions and sharing options of the folder associated with error 36 when attempting to transfer. Right-click or Control-click on the folder and select Get Info. At the bottom of the expandable list, look for Sharing & Permissions, expand it, and check if your user account contains permissions to read and write. If not, click on the privileges status and select Read & Write. You might need to sign in with an administrators account if you are unable to change the permissions. Another useful solution is to boot your computer into Safe Mode, an option used in many problematic situations - try this mode to solve error 36. To boot a Mac in Safe Mode, first shut down the machine. Once it has shut down completely, launch it again. When you hear the start-up chime, hold down the the Shift key until you see the Apple logo. When the Mac is fully loaded, try to move the folder. If this resolves the issue, reboot the computer in the usual manner.
