There are many and varied programs that allow us to get rid of the useless space of our Mac by removing different languages (Monolingual), clearing the cache (Onyx) or even removing the PPC / Intel code (XSlimmer), but there is only one that has everything: MacKeeper.
This great program simplifies the task by making everything possible in one click, something that on the other hand does not fill me with security, lest we load something that does not interest us, but we must admit that it is very comfortable.
On the negative side is that the program is not free and it has a cost perhaps higher than what people would pay to clean their Mac, but if you have little time or are lazy it may be worth it.
