MacBook Pro M1 Pro 14” speaker system sounding a little bit muffled

[tribal crane]

If you listen closely, you can hear that the speakers sound weird, like they rattle or something. What is causing that?

Actually you don’t really need to listen closely to hear it

[final path]

From what I'm hearing it just seems like the normal bass rumble. I dont hear anything "weird" or rattling about it.

It's just the good bass in ur MBP i think 😭

[tribal crane]

Idk seems weird

lol

[final path]

they have subwoofers to vibrate lol

that might be the culprit

[tribal crane]

Thanks for helping

[final path]

No worries!

[tribal crane]

Idk what’s that lol

[final path]

Oh they are located in your Macbook Pro that enhances bass.

[tribal crane]

Oh

I didn’t know the MacBook had subwoofers

I read online I’d only had something like cancelwoofers or something like that

Force canceling woofers

[final path]

However, upon closer listening there might be sth in your macbook rattling, like a screw has come loose.

Is it still under warranty?

Also forgot to ask what level is the volume set at?

[tribal crane]

Well I bought it refurbished like a month and a half ago

[tribal crane]

Actually pretty low

It was Somewhere here when I took the video

[final path]

Does it always rattle?

Or just specific frequencies

[tribal crane]

I noticed that it rattles on like low frequencies

Humming noises

Things like that

On higher frequencies I don’t notice it

[final path]

Yeah might be the subwoofer bass vibration

Is it possible to get the MBP checked out?

[tribal crane]

I don’t think so. I don’t have any Apple stores in my country and I don’t have any Apple certified services in my city…

Also I have another thing that I wanna ask that isn’t related to the sound system. Should I create another post?

It’s about the screen

[final path]

Whats wrong with it?

[tribal crane]

The keyboard makes these marks

On the screen

And they don’t come out

[tribal crane]

And also…., the hinge makes some cracking sounds

[tribal crane]

I saw a Reddit post from 2 years ago from someone that had the same problem and I wanted to see if I did something that caused it or something

[buoyant hare]

just wipe it clean

it was from the keyboard

[tribal crane]

He said to keep a microfiber cloth between the keyboard and the screen but i think that would mess it up even more

[tribal crane]

The thing is that I tried doing that and it doesn’t come off

[buoyant hare]

never put anything between the screen and keyboard. ever

[tribal crane]

Okay thanks for letting me know lol

[buoyant hare]

have you tried with 70% isopropyl alcohol?

[tribal crane]

No lol I don’t have that

[buoyant hare]

ye. it can be really bad. putting pressure on the screen and all

[buoyant hare]

have you tried water?

[tribal crane]

So you’re telling that it’s not permanent

[tribal crane]

Yes

[buoyant hare]

get some isopropyl alcohol

[tribal crane]

And a glasses cleaning cloth

[tribal crane]

Alright I’ll try to get that

[buoyant hare]

any soft microfiber cloth

[buoyant hare]

😄

[tribal crane]

I am now scared to close my laptop lmao

I close it like halfway through

[buoyant hare]

as long as nothing is in between it you're fine don't worry

do you see why keyboard covers can be bad?

[tribal crane]

The thing is that I had some debris on the body of the MacBook and the next day I saw that the debris got in the screen. I didn’t even notice them until the next morning

[tribal crane]

Yeah

But I don’t understand why it makes those marks. The keyboard is pretty clean

[buoyant hare]

i always routinely clean my keyboard

and I like to keep my screen clean

maybe develop those habits

[tribal crane]

I’ll try

I also noticed that the trackpad shows too

On the screen

[tribal crane]

Exactly like in this photo but not that pronounced

[buoyant hare]

👍

[tribal crane]

Anyway, thanks for all the help

[buoyant hare]

Let me know in here if the alcohol ever works

[tribal crane]

Alright. I’ll try to go to some stores to see if I can find any

[buoyant hare]

@tribal crane Were you able to clean your screen?

Here are some additional resources:

Is it OK to use a disinfectant on my Apple product?
Using a 70 percent isopropyl alcohol wipe, 75 percent ethyl alcohol wipe, or Clorox Disinfecting Wipes, you may gently wipe the hard, nonporous surfaces of your Apple product, such as the display, keyboard, or other exterior surfaces. Do not use these cleaning products on Apple Vision Pro as they may damage the device. Don't use products containing bleach or hydrogen peroxide. Avoid getting moisture in any opening, and don't submerge your Apple product in any cleaning agents. Don't use on fabric or leather surfaces.

I haven’t bought the isopropyl alcohol yet..

[buoyant hare]

All good.

[tribal crane]

Thank you

[buoyant hare]

Of course!

[tribal crane]

Hello. Sorry for bothering. I found this at my local store. It says it’s a disinfectant with 70% alcohol. Will it work?

[buoyant hare]

no, isopropyl alcohol

[tribal crane]

Oh alright

[buoyant hare]

is that it

[tribal crane]

Thanks

[buoyant hare]

np

[tribal crane]

Well it doesn’t say it’s isopropyl alcohol

I’ll see maybe I find it at a pharmacy tomorrow

[buoyant hare]

ye i dunno if those are the same

sorry

[tribal crane]

No problem

[tribal crane]

Will these work?

Chat gpt said that they are great for that

Cuz it doesn’t have add ons

[buoyant hare]

it doesn't have alcohol

[tribal crane]

So it wouldn’t do anything

[buoyant hare]

you can try "whoosh screen cleaner"

[buoyant hare]

not necessarily. but for your case you wanna try something other than water (have you tried water yet?)

[tribal crane]

Omg that’s so expensive

[tribal crane]

Yes

I have tried water

I’ll try it again once I’m home maybe I didn’t insist enough on it idk

But I wont apply pressure

[buoyant hare]

you don't have a screen protector on, do you?
