MacBook Pro 14" 2021: что то двигается в корпусе при небольшой тряске

Sat, 29 Oct 2022 11:50:20 -0700

При небольшой тряске в горизонтальном положении что-то двигается внутри корпуса будто что-то плохо закреплено. А при открытом экране чувствуется что именно под клавиатурой ближе к экрану трясется. Кажется что это вентиляторы, но я могу ошибаться. В форумах поспрашивал два владельца таких же макбуков проверили на своих маках и сказали что у них нет такого, но есть люди у которых есть данная проблема на MacBook 2015-ых годов. В ютуб также есть видео с 2015 макбуками. говорят что Apple не считает это за проблему. поэтому я даже не знаю стоит ли отдавать в сервис на проверку если все нормально работает сейчас

Заметил, что при тряске когда немного зажимаю экран (в закрытом положении) звук пропадает

MacBook Pro 14" 2021: MacBook Pro 14" A2442 flat battery

Wed, 29 Jul 2026 17:13:31 -0700

Went out on vacation last week and don't remember if I shutdown my MBP 14". When we came back on Friday and tried to power on the laptop, initially it was not powering on, so we tried connecting the MagSafe 3 for us to know whether it was going to take the initial charge. As these newer models work with the internal chip reconizing power before it enters to the mainboard, the laptop cannot take any power if the battery is 0%.

After realizing that MagSafe was not working, I tried my wife's iPhone's USB-C to USB-C and connected it to the MBP power brick. When doing that I saw the battery in red which indicates that the battery is fully drained. This had happened twice and connecting the USB-C from the iPhone helped charging the laptop for 10 minutes and then MagSafe worked perfectly - but this time it didn't work at all.

Tried out DFU "revive" with no luck as I tried connecting both laptops using the same iPhone USB-C cable and no power connected to any of them.

Need to know whether I get a USB-C 3.0 will help for me to start the process of DFU (as it didn't work with the iPhone cable).

Will this resolve my battery issue, should it be better to leave the laptop charging with the MagSafe or USB-C overnight?

MacBook Pro 14" 2021: Why does my MacBook hard crash after opening lid?

Sat, 18 Jul 2026 07:05:07 -0700

I have a M1 Macbook Pro 14" (2021) that I have been using for 4 years. For a long time, I simply used the OS it came out of the box with (macOS 12.1). It never gave any issues and I was too lazy to update it. One day I simply opened the lid of my macbook and tried to use Touch ID to open lock screen. After several attempts of trying to use Touch ID (it has a tendency to not work first time), I realized my mac froze and then a hard crash occurred (apple logo flashed).

I tried to force restart which led me to the black screen with exclamation mark. There was no trackpad haptic, power button was unresponsive, MagSafe LED did not work. Since I didn't have a secondary mac for a DFU restore, I simply kept my mac in isolation for a while and didn't touch it. 2 days later I plugged my mac in using Magsafe and the LED lit up.

After a full charge, I opened my macbook which showed how it restarted due to a problem. The logs said it was a kernel panic. After digging, i decided to update my OS to the latest version (macOS Tahoe 26.5.2). I thought it would fix every problem. However a few days later, the same thing happened. I opened the lid, spammed Touch ID for it to register, and then it simply hard crashed and I had to wait another 2 days for it to boot up again (same symptoms). This time there was no kernel log reports and my mac thinks absolutely nothing went wrong (I checked console and there was no crash logs or anything)

The only thing I found using the command
pmset -g log | grep -E "Failure|Sleep|Wake"

was:

What is wrong with my macbook? Is it a Touch ID issue or some other hardware/ software related problem?

Things to keep in mind:

1. I installed battery toolkit and used it in this month. I never had any issues with battery but decided to use it since my capacity was 85%. Cycle count is at 483. Condition is normal

2. I did not perform a full wipe when updating my OS from 12.1 to 26.5.2

3. After my macbook booted up, there were no other problems and it worked as intended.

4. Apple diagnostics says there is nothing wrong with any of my hardware (including Touch ID and Battery)

Update 1: Did a workaround by disabling lock screen entirely and removing touch ID as they were usually the causes of hard crash. After leaving my mac overnight with lid closed (not shutdown), it was simply dead right off the bat. I digged up some logs using the same command as before:

MacBook Pro 14" 2021: MacBook Pro 14” 2021 (A2442, M1 Pro) — Adding thermal pads on heatsink

Thu, 25 Jun 2026 06:30:52 -0700

Hi everyone,

I have a MacBook Pro 14-inch 2021 (A2442, M1 Pro) and I want to improve cooling with the easiest/safest method possible.

I don’t want to do a full logic board removal right now if I can avoid it. I’m planning the “add thermal pads” mod — placing high-conductivity thermal pads on top of the metal heatsink/radiator so heat transfers better to the aluminum bottom case (turning the whole bottom into an extra passive heatsink).

I’ve watched some of Your videos and others but there is not a video for my question (what i want).

My questions:

1. For the easier bottom-case-only version, is 1.5mm or 2mm thick high W/mK pads (Thermalright / Gelid / Arctic style) the best choice? What size sheet should I get and where exactly on the heatsink should I place the pieces?

2. I will leave Apple’s original grey paste on the main SoC and the black thermal gel (TCRS Carbon Black) on the RAM chips completely alone. I dont wanna touch them i want to add more too cool it down.

4. What kind of real-world gains have people seen on the 14” M1 Pro specifically (temps, fan noise, sustained performance)?

5. If the pad mod isn’t enough later, is the full heat sink replacement guide the right next step, and do you recommend Noctua NT-H2 or Arctic MX-6?

I will make pictures when i do this and share it with you here so people to know excactly what to do.

I want to share my exp. With the chat bot i think i have all answers to my questions i have what i need but you people can read as well and maybe my questions can help.

This is a conversation with AI asking question of how to apply thermal pads with Pics. And extra questions.

MacBook Pro 14" 2021: Can I replace or fix the microphone?

The microphone on my M1 Macbook Pro is very muffled.

After some investigation, I'm fairly sure the problem is a blocked grille. But it's hard to identify which (if any) of the hundreds of dimples on the left-hand side are actual holes and therefore need cleaning. Is there any information on this?

MacBook Pro 14" 2021: 14-inch MacBook Pro display: Staingate issue

Wed, 27 May 2026 14:51:04 -0700

Hi everyone,

I am noticing an issue with the display on my 14-inch MacBook Pro (Model A2442). There is a subtle but noticeable color shift happening across the screen. When viewing a pure white background, the affected areas look off-white/grayish. On dark backgrounds, there are permanent "smudge" marks that do not wipe away with a microfiber cloth.

It looks like the anti-reflective coating is failing or peeling (Staingate)?

Has anyone successfully stripped the coating on this specific 14-inch model without damaging the Mini-LED backlight or glass?

Any insights or advice would be greatly appreciated!

MacBook Pro 14" 2021: macOS 26.4 charge limiter not working, possibly due to replacement bat

Tue, 07 Apr 2026 19:53:50 -0700

]Not sure if this has been reported on or if I just have a weird bug but for the life of me I cannot get the battery charge limiter to work. I thought it would be nice since I rarely use it for more than a few hours at a time and figured it could save me the hassle of replacing the battery again, or at least offset it. Admittedly I do not know if it is due to the battery being aftermarket or if it is just modern macOS doing modern macOS things, so I am just seeing if anyone has similar issues.Edit:

MacBook Pro 14" 2021: New ifixit battery won't charge

I've just installed a new ifixit battery (from the "MacBook Pro 14" (A2442, A2779, A2918) Battery" ******kit). My macbook recognises it as a new battery because the health is 100%, compared to my last battery which was around 70%. After I first installed the battery and plugged it in, it immediately said it was at 62% battery and would not charge at all. I left it charging for two hours and shut it down for long periods of time, but nothing has worked so far.

or it will risk cracking the LCD glass on assembly process cause by pressure or movement while fitting it into bezel?

MacBook Pro 14" 2021: Trackpad rubbing screen after battery replacement

Wed, 05 Nov 2025 15:11:20 -0700

I recently did a battery replacement on my 2021 14" MacBook Pro. Part of that procedure involves removing the trackpad, which I did. I thought I had secured it correctly, but it seems that the trackpad may have been sitting a little too high up, and it has rubbed against the screen, which makes it appear there is a constant smudge. I've obviously tried cleaning it off, to no avail.

Last night I took the trackpad out again and did my best to reseat it correctly.

I'm still not sure if it's correct--compared to my work laptop (a 2024 MacBook Air) the trackpad is clearly indented a fraction of a millimeter -- you can feel it with your fingers when you swipe off the trackpad. On my MacBook Pro, some edges of the trackpad feel like they are underneath the chassis, while others (especially the bottom right corner of the trackpad) feel perfectly flat with the chassis.

Some questions:

1. What is normal for a 2021 MacBook Pro? Should the trackpad be slightly indented below the chassis? (P.S. this is why the repair manual needs more than just "do it in reverse")
2. As I have things now, is it likely that the trackpad is still rubbing on the screen? I'm probably going to want to replace the screen now, and I don't want to spend $500 and then ruin the new screen because the trackpad still isn't right.
3. If the trackpad is wrong, how can I get it lower? I've already tried reseating it, and it does not seem to want to go any lower in the chassis. Am I missing something?

MacBook Pro 14" 2021: Power issues with both MagSafe and USB-C ports

Mon, 03 Nov 2025 17:21:03 -0700

I had a problem with my MacBook pro 2021. M1 chip and was only using it about a year when I was having problems where it wouldn't charge.

So I sent it to some guy on YouTube or company on YouTube in Virginia. They charged me $200 to tell me that I need to have parts replaced on the circuit board that will cost me over $1,000 or $600. And then I found the guy on eBay and he's been working on my laptop and said that there were about four capacitors that shorted out.

So I think that your problem's probably related to bad capacitors. It could be shorting out the rest of the board so it's best not to have it plugged up at all. And if you're looking to have somebody fix it, you probably will have to pay about $300 to $400 if you go with somebody off of eBay

MacBook Pro 14" 2021: MacBook Pro 14-inch M1 Not Charging via MagSafe or USB-C

Mon, 03 Nov 2025 14:42:41 -0700

My MacBook Pro 14-inch M1 refuses to charge, whether I use MagSafe or USB-C. It only charges very slowly when the MacBook is powered off. When it's on, the LED stays orange (without blinking), but there’s no charging happening.

I also found that one of the USB-C ports on the left side isn’t functioning at all—it doesn’t detect USB drives, while the other USB-C port works fine (though still no charging).

I followed tutorials and opened the MacBook, but everything looks intact. All the ports appear undamaged, and there’s no visible wear or issue.

This problem started suddenly, with no prior warning or incidents. I’ve been using the official Apple charger and cable.

As part of troubleshooting, I tried downgrading macOS using another Mac, but that didn’t help. I've also tried replacing the faulty usb-c and MagSafe connectors with ones from a working MacBook Pro, but the issue persists. I’m starting to suspect that the logic board is the problem, even though I haven’t done anything to damage the Mac.

At the moment, the battery is at 100%, and the MagSafe LED is green, but the Mac still isn’t recognizing the Apple Power Adapter (see attached photo).

Do you have any suggestions on how to proceed?
