Running OnyX on my Mac will speed it up That's a generalization; there's no such thing as just 'running Onyx' because it does a lot of different things that must each be run individually. Some features are just extra settings that don't have any effect on speed, especially the cosmetic ones. Some are diagnostic in that there's no reason to use those features unless you notice something's wrong. Some are maintenance features that might make your Mac faster, but only if it's slow because something's in a bad state.
Some Onyx features might actually slow down your Mac. For example, some users think they ought to 'clean their caches' (which is one thing Onyx can do).
But the purpose of caches is to speed things up. Cleaning caches usually makes the Mac slower for a while until the caches can be built back up. So cache cleaning is only there to resolve problems with the cache, not to guarantee that you will 'speed things up.' For a normally functioning Mac, Onyx probably won't make any difference in speed. Onyx is a wonderful tool, though. Using Onyx can be a good idea if you are enough of a power user that you know why each setting is there, you know what it is you would specifically like to change about your Mac, and you know which specific Onyx settings will do that and which ones will not.
When it comes to Mac optimization, choosing the right software can be a hard decision, especially if you don’t want to fill your computer with tons of apps. So there are several factors you should consider before you even download an app, particularly whether it is user friendly or not and how much it will cost you. Mac force quit shortcut keys. Ask yourself: will I understand what it does when it performs a task?
Can I automate tasks? What kind of features does it pack, and which ones will I need to use the most? These are all questions we answer in our reviews of CleanMyMac, a paid and much favored Mac optimization solution, and the free software OnyX that has a long-standing reputation in the field. In this comparison you’ll get more insights into how the qualities of the two compare to each other.
Customer Support OnyX CleanMyMac X 24/7 n/a Email Live Chat On Call Remote Desktop Community Twitter Facebook OnyX Designed by Titanium Software, is free Mac maintenance and optimization software that has been around since OS X Jaguar in 2002, and so it has had a ‘few’ years of experience in this area. OnyX has a nice, clean user interface that provides you with details of what you are about to do using this third-party software. Some tasks – such as repairing disk permissions and clearing out various different cache files – can be done manually, but with OnyX there are specific scripts listed under different menu items, including maintenance, clearing, automation, utilities, parameters, info and log. Select any of these and you’ll find additional information about the task you are going to perform. OnyX requires your input before selecting each task but, unlike some of its rival (and paid) apps, it doesn’t give the user the option to go through the files it is going to delete after you hit the “Execute” button. Automation Option After launching OnyX, the app will prompt you to verify the startup drive and it will do so every time you relaunch it.
