I would advise caution about using Onyx: it provide a GUI front-end for a large range of utilities. Running all of them, in the hope that one will fix your problem is a ‘shotgun’ approach, and can even cause new problems. (For instance, clearing caches will slow your computer down until they are refilled.) You really need to know what the problem is first and run the particular task that might help.
I would recommend EtreCheck, which gives you a report on the state of your computer, and highlights potential problem software. http://etrecheck.com
