MacKeeper is not really needed, but if you want to use it, then go with it.
My advice is to look at the MacRumors Guides on this subject, one of which simsaladimbamba linked to above. There are a bunch of other useful guides here, including Cleaning Your Mac's Hard Drive, Deleting Preferences Files, and Troubleshooting Software Problems.
That works most of the time. You can often find most of the leftover files via a quick search. Occasionally uninstalling something properly will require a script, but that's not common. It's usually if you're working with beta versions that you run into complications.
AppCleaner does not find all files.
And CleanMyMac: cleaned too much
That is not a really good comparison, as you left out VLC in your earlier post.
Fixed that for you.
In my tests, Finder found all 17 files. AppCleaner only found 6 of those. Even if it finds 11 on your system, it's still not finding all files. Neither will CleanMyMac. No uninstall app will find and remove all associated app files consistently. Only the manual method consistently finds all the files.m8 i said vlc had same results as Skype 11 with app cleaner, 10 with cleanmymac
It really doesn't have to be a hassle. Dragging an app to the trash is sufficient to remove the app in most cases. With few exceptions, the files left behind typically only take up space and don't affect performance at all.
It's your Mac, so you can use what you like, but I would recommend that anyone with CleanMyMac uninstall it. There have been too many reports of problems with it.
That's exactly what the manual deletion method does, so you don't end up with "orphaned" folders.
What would be improvement? If those folders there take up valuable space (from 10 MB to several GB), you will probably know, from which application they are, and you would already have found them. If they only take a MB or three (if ever), then there is no real reason, unless one to three MB are a life saver.
A safer alternative for cache cleaning is Onyx, which has a great reputation. Even then, it's not necessary. You really don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space. It will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space.Agree with both of you
One of the nice things about Onyx is that it can ensure that the cron scripts are actually run. You can take care of a number of housekeeping features with a couple button clicks. I like it. Macs and Windows can both go relatively maintenance free these days, but running basic stuff like that can help just a bit. I haven't had much in the way of spyware/malware problems in Windows these day. In OSX I run Onyx and Disk Warrior.
The Mac maintenance scripts run without any user or 3rd party app intervention. You can install Maintidget which will tell you when the scripts last ran, as well as force them to run. If you don't do anything, you'll see that they run anyway. If your Mac is shut down or asleep when they're scheduled to run, they automatically run the next time your Mac is on.
