What Is Causing Mac Error Code -36?
Error code -36 is related to Finder actions such as moving, copying, or deleting files. It usually means that the Finder cannot access some or all data in the file. The error message will display which file is causing issues. The file name may have a ‘.’ before its name, and an ‘_’ later in the name. An example of this is ‘.DS_Store’. This ‘.’ means the file is hidden in the Finder. The error code -36 indicates that the file cannot be read or written.
When Error -36 appears, it typically means that a file with a dot (.) and an underscore (_) in its name has become corrupted or has some other issue. This prevents the Finder from being able to transfer, delete, or move the files because it cannot access the required information.
To sum it up, the reasons for this error message to appear could be the following:
- Damaged or corrupted files on the external drive;
- A pending update of the operating system;
- A malware-related problem.
Is Mac Error Code -36 Dangerous?
This answer depends on the cause of the error. In most cases, the error is related to data transfer, and it shows up when using Finder to copy or transfer files to or from an external drive. However, there may be cases when a malicious program is causing it.
How to Fix Mac Error Code -36?
There are several fixes you can try to solve this error.
Option 1. Run the dot_clean command in Terminal
