How to permanently delete files on mac without any chance of recovery

Permanent Eraser is a free, professional secure deletion tool for the Mac platform, available for download from the official website. It specialises in high-security file obliteration, employing the 35-pass Gutmann algorithm to permanently delete files on Mac. The utility also supports drag-and-drop operations and replaces the system Trash with a secure shredder, making it an essential tool for routinely clearing sensitive files.

How to permanently delete files on mac

1. Download the appropriate installer from the official website and launch the software

2. Drag-and-drop deletion: Directly drag files or folders requiring permanent deletion into the software window; confirmation will execute secure deletion

3. Right-click quick deletion: After installation, right-click files in Finder and select relevant deletion options without opening the main programme

4. Secure Trash: Enable the ‘Replace Trash with Secure Trash’ feature within the software. This replaces the original system Trash with a secure version, where dragged files are automatically deleted using secure algorithms.

5. Open the software's preferences to select deletion algorithms, configure post-deletion notifications, preserve file directory structures, and adjust other settings as required.

Disadvantages

• Supports only mechanical hard drives, with poor compatibility for solid-state drives. Due to SSD wear levelling mechanisms, traditional overwrite algorithms cannot achieve precise data coverage.

• Limited functionality, focusing solely on secure deletion without advanced features such as file shredding or partition erasure.

• Lacks batch custom deletion capabilities, preventing the application of different deletion algorithms to distinct files, thereby restricting personalised operations.
