Agreed. My Mac has Maintenance by Titanium Software on it which I run once a week and that is all it needs. Have to laugh at the four bogus reviews above too.

Agreed it does say a lot about the moral quality of the developers that they resort to sock puppet accounts to post bogus reviews.

Or maybe they didn't. Maybe it's a startling coincidence that both piec6404 and quhuiq2372 both found themselves expressing exactly the same thoughts - in exactly the same words.

Amazing.

Though I still have no idea why you feel the need to run an app like that every week. There really is no need.

Hi Shiny22, I have an old 2006 iMac which in all this time has only played up a couple of times like spinning beach balls and having to force quit apps too often. On both occasions Maintenance fixed this for me. I've read that repairing the disk permissions regularly is good for the Mac too. On one occasion a friend of mine had problems with his Macbook and running Onyx fixed this for him. I probably don't need to run it once a week but I like having it in case and it only does maintenance tasks. Maybe the newer Macs don't need this kind of software.

Well repairing permissions is an excellent fix for permissions problems, which are really very rare. Other than that, it's quite a waste of time. There's a lot of voodoo about that as in the very early versions of OS X (like 10.0, 10.1, 10.2) installers used play havoc with permissions. Nowadays it's very rare. As in, I haven't repaired permissions on this (2010) machine in years.

There really is no preventative maintenance needed on your Mac. And a lot of what's advertised - like "cleaning caches" for instance - actually slows your Mac down. Like repairing permissions, clearing caches are useful - but only if you have a cache problem. Otherwise it's a waste of time that can actually cause your Mac to run slower while the cache is rebuilt.

That's what so irritating about these apps, they charge a fortune for things that are of no value.
