Weird Noise on MacBook Pro: Troubleshooting the Problem

That weird noise on MacBook Pro can be caused by many different things, such as damaged or blown speakers, audio settings gone wrong, or a temporary issue that you can resolved when you reset the PRAM and SMC. After Apple released the MacBook Pro with a new feature known as Touch Bar back in 2017, forum users shortly came out to complain about a popping sound – their common denominator was owning the MacBook Pro with Touch Bar, albeit bought at different times and with various manufacturing dates.

It’s important to properly troubleshoot the sound problem to identify whether it’s caused by hardware or software, or if it’s merely a system update that can tackle the sizzling or popping sound. First, determine if it’s the speakers or the audio settings at fault. Plug in your headphones and start listening to anything with sound. If the sound comes across as clear on the headphones, then that means the problem is related to software. Blown speakers, for instance, may crackle at high volumes.

If your audio woes happen only while you play specific songs, videos, or other files, then it’s likely that the files are corrupted or suffer from low quality. If the problem persists, too, even if you listen from a CD or DVD and not directly from your hard drive, then you can proceed to troubleshoot the sound settings.

Before you try one of the fixes we provide below, make sure to always keep your MacBook Pro in tiptop shape by diagnosis your system regularly, cleaning out junk, and eliminating space hogs using a reliable Mac repair tool.

How to Solve Speakers Crackling and Other Audio Issues on MacBook Pro

Here are some methods you can try to solve the sound problem on your machine:

Checking Audio Preferences

Expect audio issues when the speakers on your laptop are set incorrectly in the preferences. Follow these steps:

  1. Unplug all external devices from the USB, FireWire, as well as 3.5 mm audio ports.
  2. Open System Preferences, and then click Sound > Output tab.
  3. Choose Internal Speakers as the default option. If there are no other options, choose Internal Speakers to ensure that the option is selected anyway.
  4. Slide the Balance slider left or right while audio is playing in order to test if just one speaker’s not working right. If the problem happens while the slider’s all the way in either direction, then it means one speaker is damaged and needs to be repaired.

Reset your PRAM and SMC

Reset your Parameter Random Access Memory (PRAM) and System Management Controllers (SMC), which you can do by booting your computer while you hold down the Command, Option, P, and R keys simultaneously until you hear two chimes. Here are specific steps:

  1. Shut down your laptop.
  2. Turn it on again using the power button. Immediately press and hold the Command + Option + P + R keys. Wait until you hear the startup chime twice.
  3. Reset the SMC by shutting down your laptop, making sure that the power cable remains plugged in.
  4. Simultaneously press and hold Shift + Control + Option on the left side and the power button for five seconds.
  5. Release the keys and turn off your computer.

Installing macOS Updates

Some Mac OS X users reported hearing their speakers crackling after the 10.4.10 update, even though their speakers weren’t at all broken. To address this, update your OS to its latest version in order to patch any audio issues. Your audio woes might not be the result of your last update, but getting the most recent update just might be key to solving them.

Final Notes

Audio hiccups on your MacBook Pro can be totally annoying, but can signal a more serious problem as well. Electronics that produce a sizzling sound when electrically connected, for one, should be a red flag. It’s important to unplug it if it persists, remove the battery, and contact Apple support for assistance.

Otherwise, if you’re able to troubleshoot the problem more clearly, then you can try one of the three solutions we provided above and see if it successfully fixes that weird noise on your MacBook Pro.

In this article, we'll look at common problems and 5 fixes for these MacBook and MacBook Pro battery problems.

Why is my Mac battery draining so fast?


There can be a number of reasons. For example, different browsers consume different amounts of battery power.

In some cases, a recent upgrade to a new macOS can be the cause and therefore a temporary problem. It either stops doing this in its own time, or a new macOS patch/upgrade is sent through and once downloaded the problem goes away. It is known to happen around the time of new releases and is an issue many Mac owners anticipate.

However, in other cases, the issue is less widespread and more localized. We cover five of the most common problems and fixes for Mac users, in particular MacBook owners who have suffered from a fast draining battery.

5 solutions for Mac battery problems

1. Check and change Battery Settings

In the top menu, where the battery appears, it’s always useful to switch usage to a statistics setting, so that you can clearly see how fast it's draining.

If you click on the battery, it will show which apps are using the most amount of power.

  1. From here, click on Open Energy Saver Preferences
  2. Within this you’ve got the option to put the hard disks to sleep and dim the display when a Mac is not connected to power.

2. Switch on Energy Saver

Always useful when trying to conserve battery power on any device, and it could be a lifesaver if you happen to be out without a power cord or plug.

  1. From the  Apple menu;
  2. Go to System Preferences > Energy Saver
  3. Now click on the Battery tab
  4. A slider should be on this screen: Switch Power Nap off, while sliding the scale along to ensure the screen goes dark after a reasonable amount of time when not being used, which should reduce battery drainage.

3. Find out what is using energy

When investigating a fast draining battery, it’s always useful to know what is using energy in the first place. To find out, follow these steps:

  1. Go to Applications;
  2. Click on Utilities > Activity Monitor;
  3. Activity Monitor will show what is taking up CPU and GPU;
  4. Giving you the ability to close anything that is clearly taking up too much battery power.

4. Identify background apps

Behind the scenes, most Macs can run dozens of apps without us realizing it. Some of these could be running because we forgot about them. Others open during the startup sequence. And others, without us knowing it, could be malware or ransomware, or other viruses, either designed to steal data or steal processing power to mine cryptocurrency or even run remote DDoS attacks.

Now, clearly that sort of thing isn’t ideal and you won’t want apps running that drain power, steal data, or that use your Mac for something you aren't even aware. To solve these potential battery draining problems, we recommend taking the following steps:

  1. Download CleanMyMac X (for free, here)
  2. Click on Uninstaller
  3. It will run a scan of every app on your system: Either click to rest or safely uninstall everything you don't need or aren't aware of.

Also, click the Optimization tab in CleanMyMac. You’ll find the tool called Launch Agents.

It displays tiny background applications otherwise non visible to a user. This very often gets exploited by advertising scripts — a sure way to drain your battery power.

As you can see, these items can be easily switched off using the Disable button.

5. Adjust screen brightness

The brightest lightbulbs consume more energy, same is true for your screen's lighting. In your Preferences, look up Displays settings and do a couple of tune-ups there. Make sure to tick 'Automatically adjust brightness' checkbox.

6. Clean up your Mac

Macs battery benefits from various forms of cleaning. Why? Because the cluttered hard drive uses more CPU resources. The more strain on CPU, the more it affects and eventually wears off your battery. There are dozens of pretty good tools to remove hidden junk from Mac but my personal favorite is CleanMyMac X. It's so enjoyable to use even for such a trivial operation as deleting junk files.

  1. Download CleanMyMac X — here 's a link to a free edition
  2. Click on the System Junk tab

As you can see, I was able to remove 18.9 GB worth of useless files: caches, broken downloads, localizations, etc.

Sit back and know that with a tidy Mac, with it free from all of the clutter of years of use — and a monitoring system in place to look after it — your battery should be operating at optimum levels again.
