- How to Change the Process Priority on a Mac. Part of the series: Macs & Other Tech Tips. Changing the process priority on a Mac is a really great way to give your computer a bit of a speed boost. Change the process priority on a Mac with help from an experienced Apple retail professional in this free video clip.
- The default priority is zero, positive values are 'nicer' (that is lower priority) and negative values are 'less nice' (higher priority). Looks like Mac OS runs from +10 to -10. Use renice to change the priority of a process already running (from the renice man page on 10.5).

I use Handbrake to convert video files all the time. It works great. Unfortunately, converting videos takes a lot of computer power, and my trust Macbook Pro is getting a little old (nearly 3 years since I bought it — that’s like middle aged in computer years). That means that when I try to convert a video and simultaneously work on other stuff, things get a little choppy, and sometimes downright unusable.
Better yet, since you can use the same data between the iPhone, iPad, Mac, and Apple Watch, there’s no need to buy separate versions for each app as you might with a third-party alternative.
Luckily, OSX has a built-in command in Terminal that lets you reset an app’s priority. It’s called the “renice” command, and here’s a thread all about it. While I’m learning to use Terminal, I still find a GUI much easier. Unfortunately, several of the apps featuring a GUI won’t run on OSX Lion. However, I found an Applescript in this thread that seems to do the trick!
I changed a few things and packaged it up as both an Applescript (for those of you that might want to tweak it more), and an application (for those of you that want to just click and have it work). Seems to be working — I turned Handbrake down to 10, and I’m suddenly able to get work done in the meantime. My understanding is that this will make the conversion slower while I’m working on my comp, but that when things quiet down, it will go back to full throttle using Handbrake, since there are no active higher priority jobs.

Note the range from -20 to 20, where positive numbers will decrease the priority and negative numbers increase the priority, with the default priority right in the middle at 0.

About the lithium-ion battery in your Mac notebook
Mac notebook batteries use lithium-ion technology. Lithium-ion batteries charge quickly, are long-lasting, and currently provide the best technology to power your computer.
All rechargeable batteries are consumable components that become less effective as they get older—and their age isn't determined only by time. A battery's lifespan depends on its chemical age, which is affected by factors such as its temperature history and charging pattern. As your notebook's battery ages chemically, its charging capacity gets smaller.
With these tips for maximizing battery performance, you can get the most out of all your Apple devices. And with battery health management, your Mac notebook can take battery optimization even further.
How battery health management helps
The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan by reducing the rate at which it chemically ages. The feature does this by monitoring your battery's temperature history and its charging patterns.
Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode. Add app shortcut mac. This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, and slowing its chemical aging.
While battery health management benefits your battery's long-term lifespan, it can also reduce the amount of time your Mac runs on one battery charge when capacity limits are applied. If your priority is making your Mac notebook last as long as possible before recharging, you can turn the feature off.

When battery health management is turned on, your battery's maximum charging capacity might be limited. Although the feature is designed to improve your battery's lifespan, the limited maximum capacity might update your battery status menu to indicate a need for service.
