How can I fix error code -8084 on Mac OS High Sierra?

1. Copy fewer files

  2. If you encounter the issue again, reduce the number of files you’re copying at the time.
  3. Do this until you find the file that is causing the issue.

2. Erase free space

  1. Go to Applications > Utilities and start Disk Utility.
  2. Now navigate to the Erase tab and click Erase Free Space.
  3. Move the slider and select the desired option and then click on the Erase Free Space

Once the process is finished, check if the issue is still there.

Alternatively, you can use CCleaner for this task. This software is designed to remove junk and old files and speed up your Mac.

In addition, the software can remove cookies and browsing history for multiple browsers. CCleaner can also remove applications with just a few clicks.

  2. In Terminal, you need to navigate to the source folder. You can do that by using the cd command followed by the path to the destination folder.
  3. Once you open the source folder in the Terminal, run the following command:

After doing that, the file should be copied to your user directory. This solution is a bit advanced, so you might have to research cd and cp commands in order to perform it properly.

4. Change server address to cifs
