Which one does the job best at cleaning your Mac and helping it run faster and smoother? After using Onyx, it gave me an extra 2.2 GB of Free Space. When using CleanMyMac, it found 11.04 GB of stuff that can be removed, but I can't remove it, unless I buy it ($29.95 for LifeTime Use). Anyway, which is better, Onyx or CleanMyMac? Or, is there a better app that will clean your Mac to have it run smoother and faster? Because I've noticed my iMac running slower than how it was when I first bought it, and I would like to have it be fast again. [Note: My Capacity is 499.76 GB, and I have 302.69 GB Available, so I'm not using much space, but it's running slower than how it was months ago].
