My MacBook Pro 2018 version speakers are crackling.

Hello. A few days ago I got the new MacBook Pro 2018 15in version. I’ve noticed since yesterday that my MacBook Pro speakers were crackling randomly. I’m not sure if since this is a new release that there are bugs in the software or if it’s an actual defect. Because before yesterday, I haven’t experienced this issue. I resetted the NVRAM and did a diagnostics test with no issues. After about 10 minutes of use that’s when it does it. Then stops. I think I might hopefully but not hopefully have to get it replaced since it’s under the warranty still. I did nothing to it. So this is dissapointing to me.

Hey! I had the same issue. I think I've managed to fix it by making sure that my MIDI output is set to 48.000 Hz. Go to Audio MIDI Setup settings, under Macbook Pro Speakers set the output to 48.000 Hz if its anything else (like 44). You might have a software installed that has changed the Hz value (and possibly some other under-the-hood sound settings as well). So far it has fixed the issue to set it back. I have not yet updated to Mojave, but has installed all updates up until that. See picture below.

I am also having this problem just today a little over 2 weeks from purchase. There are a lot of YouTube Videos starting to post what a cyclical crackle sounds like. Mine was when watching YouTube from Desktop For YouTube Application and then when playing from iTunes Apple Play.


I rebooted and now I cannot yet reproduce the crackle but I can return it and get my money back or keep it and hope its fixable in software or with Mac OS Mojave.


There have been lot of problems with the 2016 and 2017 models. Why go down that rabbit hole?

What to do?

I get a different repetitive sound sometimes(half a second echo), like a microphone feedback crackling. But I had yours as well. If I stop the audio source(youtube) the echo repeats 3-4 times then stops. Restart solves the issue momentarily.

Have you found any permanent solution. Does a replacement unit solve the problem ? Mine started doing this the first day after using it.

I ran additional tests this afternoon. I could not hear any crackling noise when I connected my Mojo. But I was only able to test for about an hour so it may be a bit premature to make a conclusion.


I have an appointment with Apple Authorized Service Provider this Wednesday night. I'm not sure what will be done there, but so far it's moving in the direction of this problem being a hardware issue, rather than software.

That's great idea to even the sampling rate - I experienced the cyclical crackle over a week ago once and I haven't been able to repeat it since - So I have canceled my return and re-purchased AppleCare plus. Kinda stressful.


Of course I totally disabled Siri for right now including hey Siri and now I'm able to sample way back down at 44,1000 No problems.


I am very hopeful that macOS Mojave will be focused on the T2 chip and perfect this as I have both the iMac Pro and the MacBook Pro 2018 having no issues since March in iMac Pro.


Thankful for the 32GB for parallels, Target Disk Mode, and VM's though -

Good luck mate! I have reset the SMC settings twice and its still coming back. I spoke to Apple support this morning and they told me that its not an issue that apple are aware of and that its most likely a dodgy time machine backup. I even had someone tell me that i must start from scratch as my time machine is corrupt so yea i hope you arent told the same thing. Even after getting given a replacement i am still having the same issues and i have an appointment at the apple shop tomorrow so who knows whats going to happen

I have now had 2 brand new 2018 MacBook pros 13 inch 2.7gig, 16 ram 2018 models with the same crackling issue. I have only one program on the Mac which is Traktor and some music, thats it. The machine is not being pushed. With the first one it was intermittent and with the headphones in I would get a sort of crackling sound. With this second one the sound problems are more consistent and it echos as well as crunches. I am so annoyed at Apple, this is a Trillion dollar company, and this is a £3000 machine. This machine should be flawless at this price. The first time I called them they tried to deny this was a known problem, that was 4 days ago. The guy must have been lying, there are article all over the web about it and pages of forums talking about it (check Mac Rumors). There are a whole bunch of other issues, like my drag and drop function suddenly not working. Yesterday my Mac crashed when I was DJing. It didn't seem to be to handle my hard drive being plugged in. My 2013 Mac worked so much better. I feel that greed has consumed this company and it's fast losing my trust.

I don’t think apple released the throttle patch for the boot camp side just for Mac OS hence the extreme throttling. Just the sound issues and this throttling issued on boot camp make it so frustrating I need both Windows and Mac OS. I hope apple fixes this soon with an update to both Mac OS and boot camp. I’m heading to the apple store on Monday and see what is said or can be done. I’ve already tried resetting the smc. So the only thing I can think of is a bios update from apple or an update to reconfigure the smc or how the t2 functions as it’s a mess currently.

I returned my second 2018 15" Mac Book Pro today. The Apple Store said they haven't even heard about the sound crackling/repeating issue. I told them to Google it. Going to have to wait until the 2019 version comes out and hope it's not a flop either. Very disappointed in the state of the new hardware. My 2013 is still going strong though!!
