How to Fix: I’m unable or can’t copy, move or delete files in MAC because of insufficient privileges or permissions

Problem: My Mac OSX is complaining that the files im about to copy or move doesn’t have sufficient privileges or permissions!

Solution: Simply use the CHMOD trick here to recursively set all your files and directories permissions. After these are set, you will now be able to copy, move or delete these files.

You need to have administrative privileges for the following to work.

1. Open Terminal by typing Terminal in your spotlight(click the magnifying glass on the top right or press CMD+Spacebar on your keyboard). You can also open terminal from your Applications folder.
2. Type cd <Type the directory you want to give yourself permissions to here...> 
3. Type the following commands(enter your password when it asks):
sudo find . -type d -exec chmod 755 {} \;
sudo find . -type f -exec chmod 644 {} \;

That’s it! You can now backup, copy, move or delete these files.
