No - do not install that in OS X.
You do not "need" any cleaner for OS X. This ain't Windows.
Read this -
link - first - before you ever install any cleaner in OS X.
While I feel there should be some caveats there, that is a good place to start related to cleaners.
OnyX is the cleaning tool recommended for when / if you ever need one and it is free.
Do not pay for any of the cleaners using the old "Windows" keywords aimed at taking money from the newbies.
The main reason for cleaners in Windows is because every app installs junk in the "registry" which loads every time you start the computer and slows it down.
There is no "registry" in OS X and apps in general do not install stuff in system folders and do not load stuff every time you boot the system up.
If you wait to use OnyX until "after" you see some slow down that is unrelated to the amount of free space, fragmented free space or a dying drive, you may find something similar to:
My wife opens up Onyx about once a year.
I was using it about once every 2-3 months on a hard drive.
While I do have OnyX installed on my SSD, I have not had a single occasion to actually use it related to trying to solve slow down issues. And this on a 4 yr old Mac, that has gone through at least 3 in place OS upgrades.
