XENOPHILE  I used Amnesia for the full trial period, and for the last week compared it directly to CleanApp. I've also tried a few other uninstallers over the past year or so. While I like Amnesia's interface and design, functionally it falls short of these other uninstallers, particularly CleanApp.

Note that my comparisons are made using CleanApp without the logging agent installed. I prefer to keep as few background processes running as possible, and IMO a logging agent is too much overhead for an uninstaller app.

On my Powermac G4 FW800 system, Amnesia is significantly slower than CleanApp, churning the HD for several seconds after dropping an app on its window before listing associated files, compared to CleanApp's nearly instantaneous listing. Surprisingly, the files that each uninstaller identifies are not always the same; out of perhaps 20 "uninstallation," CleanApp found extra files in two instances. The other side of this coin is that CleanApp tends to list false positives, files unrelated to an application, while Amnesia never does. I prefer getting false positive hits, but for users less familiar with Mac OS X, Amnesia is the clear choice. Blindly accepting all of CleanApp's hits for deletion would soon cripple other applications.

My main issue with Amnesia are its quirks. If an app's purpose is to delete files, then it should never flake-out, yet Amnesia did this several times over it's trial period. Twice I dropped apps on Amnesia only to have Amnesia endlessly thrash my HD until I force-quit it. After a system reboot, dropping the same apps on Amnesia worked fine. And once after clicking "uninstall," Amnesia began churning and thrashing for several minutes. I checked the trash to see if Amnesia had deleted anything, and discovered that it had moved 2/3rds of my "Applications" folder to the trash. I suppose this could have been user error, but shouldn't an app designed to uninstall individual applications and their associated files give a warning of some sort before trashing the entire "Applications" folder?

Ultimately, I see little need for uninstallers like Amnesia. 90% of the time, the files left after dragging an app to the trash are harmless. For the other 10%, the files are always in a handful of locations where they are easily found. I also use the freeware app "Find Any File" which will search the entire HD. Just run a search with the app's name, and the developer or software company name.

If I'm really serious about removing an application entirely, I use "Uninstaller". For example, I tried out a humongous set of HP scanner drivers, and wanted to be able to remove them if they didn't work. Uninstaller scans the entire HD and saves its state, after which you install the software, then Uninstaller scans the entire HD again and reports exactly what files were installed. This is a brute strength approach but it is 100% effective, and the only approach worth paying for IMO.

CTKMND  Really wish this would work like it says but seems it's just another Koingo software with weird problems...

This one totally ignores anything I put in the Untouchables-panel. I don't want it scanning and showing apps that belong to the system itself which in worst case would require a reinstall of OS X i.e. those in /System/Library/CoreServices.

Tried any combinations I could think of, "/System/*", "/System*" or even the exact path "/System/Library/CoreServices" - with or without trailing slash and/or wildcard. Nothing works, it totally disregards any input. So much for "Untouchables". Do you only test your software on american localization or what? How about at least give me an error dialog box...

STILL it shows the applications located in CoreServices and I am also able to select them for removal... This seems rather dangerous don't you think?

My main reason for using a program like this would be to ease up on the manual bit. If I have to re-read every line manually I might as well use the built-in spotlight from the start.

Thank you for reading.

BOB T  I purchased Amnesia 2 months ago through MUD Promo, so, it was reasonable in price.

The documentation is almost non-existent.

However, I can not get it to do it's thing on my iMac with Leopard 10.5.

I get a (-50) error saying there is a problem with authentication. The program fails to do an uninstall!

I redid all my "permissions". Made sure I was running as an Admin".

This makes me go back to good old AppZapper.

I have un/reinstalled Amnesia w/o any change.

My communications with Koingo support ledto a bunch of nonsense on the part of their techs. After 3 unanswered replies, I finally got this from them (by re-opening the case and requesting a reply):

"Hi,

The -50 error is on our list of rogue bugs. We're sorry for the inconvenience at this time - we're continuing to look for a solution to this problem. If you find a workaround in the meantime, please contact us."

They closed the case after this reply!!!

I certainly can not recommend Amnesia at this point.

WALRUSCP  Amnesia is another foray into the application uninstaller realm, and I have to say it's off to a solid start. While AppCleaner (freeware) is probably a little better right now, Koingo is obviously working hard to make Amnesia one of (if not) the best uninstaller out there.

It seems to find all the pertinent files for the apps I have tried it out on, though I am sure like other uninstallers it misses some files for various apps that install files in odd places. Koingo has improved the scanning function considerably in just the first week, and I can only assume they will continue to do so.

Amnesia does find a bunch of apps that I cannot imagine anyone would seriously uninstall via this app (printer utilities, System Alerts and other assorted buried system apps) - it would be nice if Koingo could at least grant users the option to filter those apps out. Drag and dropping an app onto Amnesia for removal like you can with AppCleaner would also be a nice feature to add as would be adding auto scanning when deleting an app by dragging it to the trash (like Hazel).

All in all, it's at least as good as everything else out there. If Koingo can keep tweaking it as they have been, it could be the best.

CYBORG9  Amnesia does as poor a job of locating and deleting files as any of the others . After I used Amnesia, I ran EasyFind and discovered that often loads of files belonging to the software that I wanted deleted remained on my hard drive. Don't believe me? Then scan for leftover files using EasyFind after using any of the software deleters.

Appzapper, CleanApp, AppClean, AppDelete, Amnesia,.....non of them are totally reliable, in my experience.

If I want all files of an app located and deleted, I use EasyFind to do it. It may take a bit longer, but it works reliably.

DOOBIEXX  Love the company but a lot of the apps developed recently look and are a lot "lighter" in features and ease. Cleanapp is by far the best in this department. There are numerous apps that can do all of this. New ideas = new apps, not just new app = more money so develop a project to bare essential performance and then make a new one. I rather 1 great app than 5 okay apps.

SURFSPIRIT  Actually lots of good apps do the same and even better, and even for free, the best in my opinion is AppCleaner, free and fast, and you don´t even have to open it, because it can work quite well with the garbage, when your send an app to the trash it will appear an window asking if you want to delete similiar named files in preferences and so on. It's better to get your developer efforts in other kind of stuff or offer some unseen feature!

ROBOTANK  Looks good so far. I gave this a shot, and it seems to be more thorough than most other uninstaller apps I've tried (except for CleanApp, which logs installed files so it catches everything, but has been more trouble to me than it's worth). I also like the ability to directly delete files rather than moving them to the trash. The backup and restore options look nice too, though I haven't tested them yet.
