If CleanMyMac is malicious and bad for Macs, why is it allowed on the Mac App Store

Because it isn't malicious. Apple would kick it out if it was. Malice would be doing things like stealing passwords, and other criminal actions.

What it is, is completely, utterly useless. It is very well known to destroy systems that ran just fine before using it.

A lot of positive reviews means nothing. Any vendor of any product (vacation destinations, child car seat, restaurant, you name it) can be, and are often loaded with fake reviews to push their positive value up.

On the App Store, VPN software (also 100% useless) have been frequently caught gilding the lily. On top of that, some set up scary sounding popups around the Internet that your device is infecting with something, and to fix it, go purchase some specific VPN software (which would do absolutely nothing to fix malware in the first place).

So my main question is given that Apple does extensive checking on all Applications that go on their App Store, why would they allow CleanMyMac?

FWIW, Apple does not do "extensive checking" of Applications on the App Store. Apps just have to meet certain criteria. Whether they work or not or are worthwhile is immaterial.

Because it doesn't happen to everyone. I said it's well known, not a given. Making a Mac completely unbootable does happen, but not often. What does happen far more often is it slows the Mac down, causes apps to crash, etc. There are many topics on this forum alone that once the user removed apps such as CleanMyMac, MacKeeper, or other such junk, they ran normally again.

Being in the app store does not certify an app as worthwhile, of value, necessary, ...

How do you spell 'money' (?)

It's very easy to misuse CMM which will result is corruipting systems and other apps. That's not something can protect against. If you search these forums for CleanMyMac you'll find time and again situations where CMM was responsible for severe problems with users Mac and its removal fixed the problem. That's what these recommendations are based on.

Ask Apple.

I find it interesting that MacLife magazine recommends CMM.

Maybe there is a reason.

MacLife used to run ads for MacKeeper, too. The king of such crap. They don't anymore.

I wouldn't be surprised! By the way I do not use CMM.

I also would like to know why?

It's not out of the goodness of their heart. They're getting some renumeration from links to CMM on their site.

So wouldn't that be a reason for Apple not to have it as one of their apps?
