Hello, I read some articles saying that this app could make the Mac run faster and delete useless files. It is good in practice? I worry that it might delete important user and system files.
The only similar application I use on my Mac and Windows computers is CCleaner because it's light and not filled with malware like CleanMyMac is, and I am telling you that from experience rather than speculation.
Not really to my surprise, but on the Mac you really do not have to do a lot of maintenance.
Almost all of these cleaning up, speeding up, anti virus, this and that apps .. They're all just really bad, cause trouble, harder to uninstall than usual, require root password for some reason .. and change ownership a lot more than any other company.
Dodgy stuff, they're on the same list as MacKeeper etc. I consider them to be the virusses to the mac and never recommend any of these to mac users.
Just empty your trash, uninstall some apps you don't use anymore. And go through your data manually like your docs, your pics, your vids, your download folder. And clean it up manually a bit once in a while.
Getting rid of some log files will give you a couple megs, ont 500 ..
Cleaning up some cache files just means (in my book) that they will be rebuild next time and that's just performance hit again. You can just leave it alone and let the apps deal with them.
My Mac runs slow, outlook crashes. Apps take too long to open. What, other than Clean my Mac, can I do?No. 100% no. Don't download it. Just avoid any clean/speed up applications. Same advice applies for Windows.
OS X looks after itself. If you feel your Mac's running slowly, these apps won't help. Post here and we'll run some diagnostics.
