You recognize most of the processes you see when browsing Activity Monitor , but not hidden. The name is cryptic and there is no icon to recognize. Should you be worried? RELATED: What is this process and why is it running on my Mac? This article is part of our current series explaining various processes found inActivity Monitor, like kernel_task , mdsworker , installd and many others . You don"t know what these services are? Better start reading! The hiding process is not dangerous and is actually part of macOS itself. The cryptic name represents the human interface device daemon. This daemon interprets all movements of the mouse and keyboard keys, which means that it is essential if you want to use your Mac. Other input devices, such as drawing tablets and game controllers, are also supported by this daemon. It is rare for Hidd to cause problems, but it is always possible. Here"s what to do if it happens. What to do if hidd uses excessive system resources This is rare, but sometimes Mac users report that hidd is using excessive amounts of CPU or memory. In most cases, simply restarting your computer will solve the problem. is also possible to kill Hidd directly using the activity monitor. You won"t be able to briefly use your mouse and keyboard if you do, but macOS wiI will restart the demon soon after and everything should be back to normal . If high resource usage continues, the likely culprit is third-party software.installed drivers for a third party input device or software that allows you to do things like customize your keyboard shortcuts, this could hypothetically be the problem. Try uninstalling this software, then see if that fixes the problem. hidd will keep your Mac awake "style = " max- height: 400px; max-width : 99%; "> If you try to understand what is keeping your Mac from sleeping , you will find Hidd listed as a reason. heThere is a good reason for this: hidd handles mouse and keyboard input, and you used your mouse and / or keyboard to execute the command. You don"t want your computer to fall asleep while you"re using it, so hidd prevents your Mac from falling asleep as long as you type or move your mouse. Basically, the act of observation changed the results, a problem that you share with many physicists. Everything that keeps your Mac awake is probably not hidden, so go on to the next thing.
