Macs are unquestionably one of the top computing devices out there with great hardware. Unfortunately, even then, your Mac is not completely immune to problems. Occasionally, you might notice issues like your Mac crashing a lot, battery problems, or constant fan noise. These problems can worsen over time if you don’t take notice and fix it. So, make sure to keep a close watch on your device.
Here, take a look at some of the common Mac red flags and how you can fix them.
1. Your device simply won’t turn ON:
So, you’ve pressed the power button on your Mac and nothing happened? Do you continue to see a black screen? This is a problem, but you don’t need to panic. You can try these steps to diagnose the problem before taking your device for a repair:
- Check the power connections to ensure that they are secure on both ends. Also, check the wires to see if they’re damaged and use a different cable or charger.
- Try raising the brightness of the monitor to ensure that it hasn’t been turned down so low that you cannot see anything, but a black screen.
- Unplug all peripherals except the mouse and keyboard, and try booting your device again. The problem might be with the accessories.
- Try resetting the NVRAM and SMC.
2. Your Mac is restarting frequently and suddenly:
Frequent and sudden restarts that are accompanied by a warning onscreen are called kernel panics. So many things can cause this problem with hardware (CPU or RAM), an unreliable peripheral connected to your device, or low disk space. Kernel panics are nothing to worry about unless you’ve been experiencing them frequently. In that case, try these fixes:
- Remove any peripherals that might be the reason behind kernel panics. For instance, if the panics are only happening when you are plugging in your webcam, remove it and see how things go.
- Check if there’s enough disk space or delete files to create more space.
- You can run Apple diagnostics to detect hardware issues. See the guide on how to run diagnostics on Mac.
- Press and hold the “Shift” key so that your system boots in “Safe Mode”. Safe Mode can scan your volume for errors to fix the problem and it excludes third-party kernel extensions, which might be the issue.
- The last step before you reach out to a professional is reinstalling your macOS from scratch.
3. Your Mac freezes for no reason and apps crash frequently:
Does your Mac freeze for no reason? Are the apps working sluggishly or they’re unresponsive? Or, are the apps frequently crashing? These issues can be caused due to low disk space or issues with storage and memory. The possible fixes for such issues are:
- Creating more disk space by deleting the files you don’t need. For the apps to work perfectly, you need at least “10GB” of free space on your Mac.
- Checking your device’s memory issues by running “memtest86”. You can even run Apple Diagnostics to check for other problems.
- Ditch the apps that are resource-intensive and use lighter-weight alternatives.
- Reinstall macOS.
4. Power issues, strange LED behavior, and erratic fans:
The SMC (system management controller) is responsible for low-level operations that typically cannot depend on the primary operating system. If there is an issue with the SMC, you may encounter problems like, indicator LEDs and battery misbehaving, fans that are constantly running, or keyboard backlights that refuse to respond to commands. A refusal to power on and sudden shutdowns are some of the power issues that you might experience.
You can solve this problem by resetting the SMC. Here’s what you have to do:
- Unplug the power and shut down your device
- Press and hold the left “Shift + Control + Option” keys. Keep holding these keys down and then press down the power button. For ten seconds, keep pressing all of these four buttons and then let go.
- Plug-in the power cable and switch on your Mac. Your SMC should be reset.
5. Your Mac’s battery life is declining:
Batteries do not last forever and they will start to exhibit signs of wear and tear with time. For instance, your Macbook will not last as long as it used to on a single charge or it might not hold any charge at all and you always have to keep the charger plugged in while working. The obvious course of action would be to replace the battery, but that’s not your only choice. Sometimes, power issues might be related to the SMC.
You can try the following fixes if you’ve been noticing battery issues:
- Check the health of your device’s battery. If the battery truly is in a poor condition, you might have to replace it.
- Reset the SMC (follow the steps mentioned above) if the battery is in a good condition, but you are still facing power issues.
- You can adjust your habits so that battery life can be extended. You can start by checking which apps make use of the battery and if you’re not using those apps, you can close them. For web browsing, you can use Safari because it is much more efficient than Chrome and Firefox.
Just like any electronic device, your Mac will need repairs and replacements at some point. Depending on the cost, you can decide whether it would be better to upgrade to a newer model.
