I have poked around but can't find anything and a right click of the mouse on the file does not give an option to shred like one the PC version.
Hello.
Unlike the Windows version of Bitdefender Total Security, the MacOS version of Bitdefender Total Security doesn't have a File shredder module/option.
I'm a Windows user, but reading this article:
it seems that MacOS has a built-in file shredder.
Regards.
