There is nothing more frustrating than using your Mac computer and it suddenly starts to slow down or stagnate. This is especially true if you are in the middle of a project and have to restart your PC, which will cause you to lose all your progress. It may seem that it takes forever to complete a task.
Depending on what causes your computer to freeze, we have listed some solutions and the inclusion of in-deep steps has helped you get to the bottom of the problem.
Force abandons unresponsive apps
If your Mac is unresponsive, the first thing to check if an app is frozen is because sometimes it can also lock your Mac. If an app is frozen and skipping it will not work, click your icon in Ctrl + Dock, then hover the pointer over the Quarter button. Hold option (labeled as Alt on some Mac keyboards) and Quit Force becomes Quit; Click it.
Alternatively, try pressing Opt + Cmd + Esc to open the Force Quit window. Select the app you want to close, then click Force Quit (or reconnect the finder), then click Force Quit on the confirmation dialog box.
If your Mac is completely turned off and the above steps will not work, then press Ctrl + Opt + Cmd and power button at the same time; This will reboot your Mac.
Reset system management controller
The System Memory Controller (SMC) takes care of everything behind the scenes in your Mac, from battery management to keyboard backlighting. If your Mac stays freeze, SMC may need to be reset.
What you do depends on whether your Mac has a T2 security chip. If you’re using a MacBook, which means (at least you don’t have a 2016 or newer MacBook Pro), turn it off, then press Shift + Ctrl + Opt and the Power button at the same time. Hold all these keys for 10 seconds, then let go. Now press the power button to switch to your Mac. If you’re using a Mac desktop without a T2 chip (such as an iMac), turn it off, unplug the power cord and wait 15 seconds, plug it back in, then turn on your Mac.
If your Mac has a T2 chip, the process is different. For both MacBooks and desktop Macs, power off the device, then press the power button for 10 seconds. Let go and wait a few seconds, then press it again to turn on the Mac.
If you’re using an older MacBook with a removable battery, you’ll need to follow the steps on Apple’s website.
PRAM / NVRAM reset
Your Mac’s PRAM and NVRAM are small segments of memory that store some settings that need to be accessed quickly by the computer. If your Mac is cold, it may be that one of the PRAM or NVRAM errors.
Resetting them can help, and the process is the same for both. First, turn off your Mac, then turn it on and immediately press Opt + cm + p + r. Hold these keys for 20 seconds; Your Mac may restart during this time, but hold them for a period of 20 seconds.
If your Mac normally plays a startup sound when it is turned on, you can release the keys when this sounds. If your Mac has a T2 security chip, you can release them when the Apple logo appears and disappears a second time.
Note that if you have a firmware password set, you must close it before resetting PRAM and NVRAM. Apple instructs how to turn off the firmware password on its website.
Boot in safe mode
Loading your Mac in safe mode can fix problems associated with freeze or help you identify what the problem is at first. Safe Mode verifies the integrity of your startup disk and disables some applications and processes from running.
To start in safe mode, turn off your Mac, then turn it back on and immediately press and hold the Shift key. When you see the login window, release the Shift key. If you encrypted your startup disk with a file vault, you may have to log in twice to unlock the startup disk, and a second time to log into Finder.
Now try to reboot your Mac using the normal startup process. If you are able to use your Mac without freezing, then Safe Mode has fixed the problem. If you continue freezing while using your Mac out of safe mode, you have login items (there may be a problem with those apps that load when you log in), Wi-Fi networking, or an external Devices, as they are all disabled or limited. Safe mode.
Apple’s support page has more information on safe mode, which may help.
Run the Apple Diagnostic Test (or Apple Hardware Test on an older Mac)
If the cold continues and you think it may be due to a hardware problem, run an Apple diagnostic test. First, disconnect any external devices except the keyboard, mouse, display, Ethernet connection (if you are using one), and the power cord. Make sure your Mac is on a solid, flat surface and well ventilated, then turn it off.
Turn your Mac back on, then immediately press the D key. Hold it down until a screen asks you to choose your language. Choose your language, then wait for the diagnostic test to run. This should only take a few minutes.
If a problem is found in the test, it will list them with possible solutions. It also gives you a reference code to find out any problems, as well as ways to contact Apple so that it can fix the problem.
If your Mac was released before June 2013, you should use Apple Hardware Test instead.
Take your Mac to an Apple Store
Sometimes, the only thing you can do is take your Mac to Apple and see them. If you have tried all the above steps and still cannot stop your Mac from freezing then this is the best course of action.
To find your nearest Apple Store or Apple Authorized Service Provider, go to find.apple.com and follow the on-screen instructions.
You don’t have to go directly to Apple to fix your Mac – third-party repair shops can also help. It is a good idea to make sure that the Apple you choose is an authorized service provider, as these shops only use genuine parts and must be approved by Apple for the quality of their services.
