Smart uninstall software
Many software titles on Mac OS come with the uninstall directions of simply "Drag the application to the Trash and empty it". In reality, this often leaves many related files on the computer taking up valuable hard drive space. Amnesia performs a smart scan to determine all related files to be removed.
Uninstall more than just apps
Easily uninstall not just applications, but also Screen Savers, Dashboard Widgets, and Preference Panes. Amnesia will remove logs, caches, application support files, preferences, crash reports, and other application specific files. Take the frustration and time out of searching for all of these files manually. In addition, turn on a secure deletion option to prevent recovery of the removed files.
Peace of mind
Scared to accidentally remove something you may need later? Amnesia comes with a built-in backup function which creates an archive of related files incase you wish to restore them at a later time. It will reinstall the pieces of the product exactly where they came from - even if you choose to restore to a different machine!
Protect your data
Another powerful feature Amnesia has to offer is the ability to create a list of Untouchables (in addition to the ones built-in). Untouchables are software products which Amnesia will warn you about incase a remove is attempted. This is handy incase a particular software product should be removed using a manufacturer-provided uninstaller instead.
Comprehensive feature-set
- Remove applications, screen savers, preference panes, and widgets.
- Scans for related files in many locations including the Application Support, Logs, Crash Reports, Caches, and Preferences folders.
- Securely remove files, instead of performing a quick delete.
- Maintain a log of files removed.
- Backup and Restore a set of software and its related files.
- Move a software set to a specific destination instead of deleting it.
- Rebuild the Launch Services database after removal.
- Calculate the size specific software sets are using.
- Create a list of "Untouchable" software.
- View a list of installed software sets, and choose multiple ones for removal.

User Reviews
"I feel so much better knowing that when I delete an app, it's gone. For good. Without a trace. And with Amnesia, that's such an easily-acquired feeling." — Robert Winter
"Great app! Easy to use and does exactly what it was intended to do. This one is a no-brainer and I absolutely love that when it comes to computers. Highly recommended - better than any other app out there that I've tried." — Adrian Skellington
"Doesn't just delete applications! You can use it to delete Dashboard widgets, screen savers, plugins, and more⦠and it's all right there in front of you. Extremely simple, user-friendly, and above and beyond useful. It covers everything. I highly recommend this to anyone and everyone out there with a Mac." — Sam Rand
"I absolutely love this one. Incredibly easy to use and the interface is neat and tidy. Drag and drop functionality works really well with Amnesia's features. Very, very well done." — Kurt Barrett
"All in all just a very well-rounded app. Lets you be specific with your files in the simplest way possible. Interface looks nice and is easy to figure out. Does exactly what it's told - and with the Untouchables feature, I also don't need to worry that I might be deleting something important. Always a good thing when it comes to apps like these!" — Rebecca Truant
"Well-polished. I've never had any issues. It's obvious to me that Koingo's been in this business for a while now and as a result they definitely know what they're doing." — Robert Tenor
"Excellent app and excellent support for it! Any question I've ever had has always been answered in full detail, and quickly. 10 out of 10 in my opinion. Full 5 stars." — Karen Flynn
"I love this app! I was able to delete apps and widgets that I didn't even know I had that were taking up space. I also took comfort in knowing that once they were deleted, they were deleted thoroughly without leaving any residuals. A definite must for Mac users!" — Cali Woodward
"Simple and effective. Just like dragging an app to the trash, only much more thorough and includes far more options if the need should arise. I only wish I had discovered it sooner!" — Justin Redwall
"Simple and compact way to view and review all your files. Thorough deletion process is as simple as a click of a button. Extremely useful app - Amnesia should come with every Mac by default in my opinion." — Nancy Hand
