Appriority is an easy-to-use tool for OS X that simply makes the app you're working in go faster by allowing you to optimize the CPU load on your computer. Once fully configured, Appriority works by suspending and resuming applications as you switch among them. Inactive applications can be set for suspension which will eliminate their CPU usage until you switch back to them. The benefits of this are improved performance in the application you currently have active, less battery power used while mobile, and less heat produced by your computer.

The Free Market edition of Appriority also uses the renice command to more...

It's necessary to lead the user to take good decisions or suggest some preset and clean up some not working commands.
I could make examples of confusing statement about what is suspended in a window and not in another one, what should work but is not.
But then... a good guide for the most popular and CPU sucking apps should be there (Chrome helpers, renders and other long lists of mysterious processes, most of them for sure 'suspendable' but not without risks of bad behaviours like toggling between applications

Is't there the risk to stop applications which are supposed to be active even in background instead to 'calm them down'?
Say Mail, Skype, but many other background applications, should be never totally stopped in background.
Probably two enhancements would be useful: a % ony reduction of the activity, an upper limit of it (means: stay active in background but not more than… say 1% of the CPU) with a kind of 'stop and go', without that the activity of Appriority becomes itself too high.
Even a good help about which apps should not be stopped to not regret to have done it.

Works pretty well. The auto hiding apps takes getting used to. I leave it off.

I installed Appriority and from that point on, it ran like a rock. NOTHING would open and it took nearly an hour to get to the basic startup desktop. NOTHING was responsive. I concluded that app must be the problem so I trashed it using App Delete and then restarted. From that point on my MacBook Pro ran perfectly. And this Appriority was running with the basic installed features that I did not change at all. BEWARE!!! This app is a Mac KILLER!!!

This is the old 'Renicer' shareware utility the same Company used to offer in former MacOSX versions.
Although I remenber buying this for my old Powerbook G4, I think it's pretty useless in modern operating systems with Intel hardware.
I mean, what's the point to save 5% usage in a X-core CPU?

From the moment you run Appriority, It is readily apparent that it is not the old Renicer utility we used to offer. The Mac App Store version of Appriority has no renicing capabilities at all, yet enjoys a 4.5 star rating. So what makes it useful in modern operating systems with Intel hardware?

Appriority works by suspending applications that are in the background and activating them when you switch back to them. It does this automatically as you switch among your apps while you work.

Saving 5% usage in a X-core CPU may not seem like a major boost, but if you save 5% with one app and 5% with numerous other apps, it adds up and it is obviously going to make a big difference.

You will have more CPU power in your frontmost app. Your CPU will run cooler, and you will hear the fan less often. You will enjoy increased battery life. These are great benefits whether you are using modern intel hardware, or an old Powerbook G4.

Download Appriority and try it out. It is free to try, and it is fully functional. Test it with Activity Monitor and watch how it works. It's pretty cool.

Very simple, works successfully and smoothly . Not consuming very much CPU (once main window is closed), I hope that the dock icon could be hidden (maybe a menu icon instead).
Considering also the low price, i really recommend trying this software.
