What to do if Mac often freezes. 6 ways to fix the problem

How to recognize and fix software and hardware problems.

A constantly hanging computer is incredibly enraging. In addition, because of this, the dog can go under the tail all the work that you spent several hours on. Gathered the main tips on how to bring the Mac to life and restore its previous performance.

Method 1: Force close hung applications

Sometimes not the entire computer freezes, but only individual applications – and they also do not respond to the close command. In this case, right-click on the application icon in the dock. Hold ⌥ and “Finish” will turn into “Finish Force”. You can also press ⌥ + ⌘ + Esc to open the Force Quit Applications utility.

This method is suitable if you occasionally use your computer to the limit and it does not cope. All you can do to prevent the device from hanging up is to add RAM.

Method 2: Reset SMC

The System Management Controller (CMS) is responsible for many processes – from power to key illumination. If the computer continues to freeze even under light load, try resetting the CMS. How to do this depends on the Mac model. Detailed instructions for all types of computers and laptops are available on Apple’s tech support site.

Method 3. Reset PRAM or NVRAM

PRAM and NVRAM are small segments of Mac memory that store settings that your computer can quickly access at any time. If the Mac often freezes, the problem may be in them. Resetting memory is easy:

  1. If you have a firmware password, disable it.
  2. Turn off the computer.
  3. Turn on and immediately hold ⌥ + ⌘ + P + R.
  4. Hold for 20 seconds. The computer may restart in the process, but keep holding the keys.

Method 4. Run in safe mode

Starting in safe mode will help fix problems that cause the computer to freeze, or at least determine the cause of the freeze. This mode checks the integrity of the boot disk and blocks some applications and processes.

Hold the Shift key immediately after turning on or restarting the computer until you see the login window. To exit safe mode, simply restart your Mac without pressing any extra keys. If the computer stops freezing, then the problem is resolved. If not, the list of suspects is greatly reduced.

The problem may be with applications that start when you log in, Wi-Fi, or a connected device (for example, an external hard drive ).

Method 5. Run Diagnostics

Do you suspect that the problem is not in the software, but in the physical components? macOS has built-in hardware diagnostic software that can help you identify hardware problems. To start the diagnostics, turn off the computer, then turn it on and immediately press and hold the D key. When the program opens, select the language and run the test. This usually takes only a couple of minutes.

If the problem is really related to physical components, a list of problems and possible ways to solve them will appear on the screen. It is convenient that the program indicates the codes of all errors so that you can immediately name them in the service.

Method 6. Contact the service center
