SAMADORE  Uninstaller is the ONLY stable (am keeping my eye on CleanApp) app uninstaller that lets you ensure you see EVERYTHING that an application installation puts on your hard drive. Trust me. Use this, see the items it shows you were just installed by an app and you'll realize that all the other purported 'app cleaners' do nothing but drag the app from your application folder and maybe find the odd ~/Library/Preference file and on a really good day a User cache file. It's interesting and useful to see the plethora of files (and where they go) some of these application installations scatter all over our hard drives. Can also be used as a re-installer and has uses beyond simple application file management.

Plus you get to try the other products in the MacMagna stable.  
(Version 1.12.1)

MACMAGNA  Perhaps we are not using the same version because the behavior you describe is similar to the one used in the previous release v.1.11 not in v.1.12.

In Uninstaller 1.12:

- "Save" just scan and save the item state.

- "Compare" just scan and compare against the saved state.

and:

- "Save" DO NOT compare after the scan.

- "Compare" DO NOT save any state.

Please let me know if the version you use really works differently.  
(Version 1.12)

SGHUEBNER  I am sorry, there seems to be no way to edit a review so I have to use another one. There was a typo in my last comment. The last sentence should read "...then make a *comparison*...", not "computer". Don't know how this got in there :-)  
(Version 1.12)

SGHUEBNER  Maybe I am the only one but I think the new behaviour of 1.12 is very un-intuitive compared to how it worked before. Reasons:

1. The toolbar-buttons do other things than their label suggests.

2. "save" not only saves the state, but it does a compare again. Totally useless and unnecessary as I only want to actually "save" but not want to compare again.

3. It is not clear to the user that "compare" actually not only compares but also saves the new found state.

This is bad for several reasons. In my opinion, "save" should only be available in two cases:

1. There is no earlier state

2. right after a "compare" and only once.

"Compare" should really do only "compare" and no save at all. The reason? The user may only test try a comparison to see if anything has changed. He might decide to leave Uninstaller without saving, install something else and then make a computer which then would include the unsaved changes plus new found entries.  
(Version 1.12)

MACMAGNA  Unlike previous versions, Uninstaller 1.12 use a different behavior to do its job.

The new uninstall process:

1) Select your main disc/folder and do just "Save" (this create/update the saved state)

2) Install your new app, use it, create documents, etc...

3) Do "Compare" (this create the current state and compare it to the saved state)

Now Uninstaller show you New, Modified and Removed items since 1)

4) Review New items and delete unwanted files.

That's all.

Optionally, you can update the saved state by doing "Save" again after 4) if you consider to compare later your disc/folder from this point.  
(Version 1.12)

REZA666  I have tested most of the so called uninstallers and i must say this is the only software that finds everything. all others do not find hidden files and leave files behind.

On the other hand, i think it is a little to complex to all the time exclude files not related to the install. I have lots of excluded files in my list by now.

Would be nice if there were some predefined list. Still i think this is a great software so i have payed for it.

One feature i miss is the ability to add more items to an existing log.

Also i have to scan, save state twice each time i exclude something which is a bit to overkill.

There is some room for improvments still but overall a great software.

XENOS  it's a real pain with people like THECAUSE, comparing apples with pears.

when reviewing a software, one would be supposed to knowing what they are talking about.

if it comes to seriously tracking down all new, deleted and changed files implied by an installation, you quietly can forget the whole palette of all other applications like CleanApp, Appzapper etc...

Uninstaller is the only working means of being notified about any installation process - provided you know to apply it correctly, i.e. doing an analysis and saving it before the installation begins.  
(Version 1.10.5)

THECAUSE  Consider giving the application

AppCleaner

a whirl. Its free dollars and it has a very clean interface.  
(Version 1.10.5)

MACMAGNA  If you "Scan and Save" just before the install and then "Scan and Compare" just after the install, as mentioned in the help, no system files could appear in the "New items" found excepted if you do this while MacOSX is updating itself, which is not a good idea.

To avoid catching unwanted files and to reduce, as close as possible, the found items to these relative to the installation process, i recommend to close all other applications before monitoring an installation with Uninstaller.  
(Version 1.10.5)

SCHNUCK  wrongo - what about invisible files and files that directly incfluence the system such as background daemons etc.? this is when it becomes messy. and a non-geek could easily ruin the entire system by trying to get rid of these.
