When dust blocks the airflow, the heat that does escape has nowhere to go.
Dust can accumulate on the vents, fan, and the surface of any parts. My imac keeps freezing up mac#
Avoid using your Mac in places like the couch, a pillow, in bed, or on your lap for extended periods of time.
Your Mac has vents that let fans bring in cold air and expel hot air. Here are some places to check when your fans are going crazy: But when your fan runs constantly even though it isn't experiencing heavy usage, that's a red flag. This is perfectly normal, and you shouldn't worry about it. In such cases, your fans will run heavily and make noise. 
Sometimes an app requires a great deal of processing power to complete its task. They're important because overheating can lead to physical damage. These turn on your fan and provide necessary airflow to cool critical components. Your Mac contains some vital sensors that respond to temperature changes inside your system. If your Mac boots in Safe mode, look for third-party libraries and system extensions in the Library folder.
Safe mode can help isolate many issues that result in kernel panics. Bugs in apps may lead to a low-level system crash. Also, check for updates for third-party apps. Check Apple's support page for EFI and SMC firmware updates, but know that it's been archived by Apple. My imac keeps freezing up install#
However, if you have an older Mac, you may be able to install firmware updates manually. Most of the time, macOS system updates include firmware updates.

If you find the problematic hardware, check for driver updates or contact the manufacturer. One by one, plug your external devices back in after each restart. Detach all peripherals except the power adapter, then reboot and check if it's working properly.
Faulty or outdated peripherals can also result in kernel panics. Do a detailed Apple Hardware Test or Diagnostics to check your RAM. If your RAM does not match the specifications or is even slightly defective, kernel panics or crashes can happen. macOS is picky about the quality of RAM. My imac keeps freezing up how to#
See how to free up space on your Mac to regain some. A kernel panic could be a sign that you're running critically low on disk space. Your Mac needs enough storage space to carry out day-to-day activities.Then, repair your startup drive with the disk repair utility. Restart your Mac in Recovery mode by holding Cmd + R as you boot.Remove any RAM you've recently added and restart again. RAM with incorrect specifications can also result in a gray screen.If the Safe mode boot fails or gets stuck, then reset both NVRAM and SMC settings as mentioned earlier.If your Mac completes the startup process here, restart again in normal mode and verify that your startup drive is working properly. Plug in one peripheral after each restart to find the culprit. Thus, you should detach all wired accessories, then press and hold the power button to shut down your Mac.
Faulty peripherals are the primary cause of gray screen problems. If you have a simple gray screen when you boot, here's what to do: But if the startup process gets stuck, no matter how long you wait, you'll see only a plain gray screen or one with symbols.ĭepending on what you see, follow these instructions. Once you power on your Mac, a sequence of booting events occurs until the login screen or desktop appears. This is the last step you should try before taking your Mac in for a repair. On a desktop Mac, unplug the cable and wait ten seconds. If your Mac is running, it'll cut the power and force it to restart. On a modern MacBook, press the power button and hold it for ten seconds. Plug in your peripherals after a reboot and see if it all works properly. Unplug all peripherals except your keyboard and mouse, then try to boot. There might be a problem with your accessories. Also, try raising the monitor brightness to make sure that it's not turned down extremely low. Check the video-out cable connection with the external display (if any). Next, check the wires for damage and try a different charger or cable. Check the power connections to make sure they're secure on both ends. Instead of panicking, try these steps one at a time to diagnose the problem: There's no power light, no sound, and a completely black screen. You press the power button on your Mac, and nothing happens.
