Downloading Shredo 1.2.8.2 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. This software for Mac OS X was originally designed by mymixapps.
According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. Shredo for Mac lies within System Tools, more precisely File Managers.
From the developer:
Shredo is a nice looking file shredder that allows you to securely erase files, folders and trash beyond recovery.
Brings back the Secure Trash Erase feature to macOS.
Privacy Scan feature - scans your Mac for other privacy threats like browser cookies, history and so on.
