Hey everyone,

I’m facing a sudden and stressful issue with my MacBook Pro (M4 Pro chip) and could really use some insight or advice if anyone has gone through something similar.

The Situation:

Today, I tried to turn it on after leaving it completely unused for about a week. Absolutely nothing happens. It is completely dead.

What I’ve tried/checked:

Power Source: I connected the MagSafe charger, but the MagSafe LED light doesn’t even turn on (no amber, no green, completely unlit).

Battery Level: I am highly confident the battery shouldn't be completely drained; I almost always use it plugged into the charger to preserve battery health and keep the cycle count low.

Force Restart: I tried holding down the power/Touch ID button for 15–20 seconds, but there is no sign of life—no screen backlight, no Apple logo, no fan spin, and no trackpad haptic click.

Physical Condition: The laptop is practically brand new (bought about a year ago), has never been dropped, has zero physical damage, and has never been near liquid.

It was working flawlessly the last time I shut it down.
Has anyone with an M4-generation MacBook experienced a sudden logic board failure, a bad PMIC (Power Management IC), or a known issue where the MagSafe port completely stops recognizing power? What could this be?

Appreciate any help or troubleshooting steps I might have missed before I schedule an Apple Store appointment!

I brushed the back of my fingernail against it and got a little jump off of it. My left arm aches a lot and my head hurts a little - it's been about 20 minutes though, and other than that I feel fine.

If anyone knows the voltage that runs through an idle A1224 iMac's psu, please comment. Thank you.

Hoping to get some help here. My 2017 Mac Mini only wants to connect to my monitor during boot up. I am connected to my LG monitor via HDMI cable.

When I try to reconnect I can tell he Mac is away. For example sometimes if I hit the Play button on my keyboard Spotify will start playing music, so I know the OS is awake.

Here is what I've tried so far:

1. Resetting the NVRAM
2. Replacing the HDMI Cable
3. Disabling sleep mode as there seemed to be a lot of articles about this online: (Prevent automatic sleeping when the display is off). That didn't fix it.

This is issue has been going on for over a year, so I'm sure there are more things I've tried that I just can't think of in the moment.

Most of the "how to fix" this issue articles on the web require a connected monitor. The instructions tell you where to go to change settings, assuming you have something like a MacBook.

The only "fix" is to hard power the Mac and reboot.

My Mac can't handle the workload like is used to. Is it time to upgrade? I've been waiting for the M5 to be released.

i was resetting my old mac to factory reset. after few loading screens it went all dark. no backlit. trackpad clicks. and its warm. its been a while now please someone help.

Hey gang! Been digging deep into this and wondering if anyone had any insight. Basically the title says it all. Apple was of no help. The took my comp and ran diagnostics on it for 2 weeks (pretty sure they just forgot about it) and said the Hard Drive has failed. So now instead of me actually doing the swap and replacing with a SSD; I just want to

Try and recover what I may not have backed up… So I’m going to open it up and remove the HD and I got an external dock station to try and mount the drive and gain access to whatever was on it… I know this is a 50/50 situation but does anyone have any success stories with this? From what I’ve gathered the SSD portion isn’t really going to have too many files on it so I just want to try and get what I can get basically and then chuck this thing into the fire etc. thank you so much in advance!

Hi everyone, I recently got a iMac Catalina but the previous owner didn’t log out. I tried factory resetting it by using CMD + R but that didn’t work. I tried using CMD + S too but that didn’t seem to work either or maybe I’m doing it wrong. Does anyone know what to do?

Day before yesterday i was normally using my mac and when i restarted it the screen turned black and it wont power on when i took it to the apple authorised centre they told me the logic board has failed and needs to be completely replaced and yk how much it costs like wtf? On a random day for no reason. I have always kept my mac clean and safe from all the liquid and drop damage now what to do after these price hikes?

1. Get it replaced or fixed in a third party store rather than the authorised one

2. Get a windows gaming laptop in that price as i am a engineering sophomore cause mac prices are at its peak

3. Get it repaired in the authorised store itself no other option

Please suggest me what to do?

Specs : Macbook Air M3 , 512gb storage, 16gb ram

My husband's 2019 iMac has been running extremely slowly ever since we had a power outage. He upgraded to macOS Sequoia several weeks before the outage and everything was working fine until the power went out.

Specs:

• 2019 iMac
• 3.7 GHz Intel Core i5
• 32 GB RAM
• macOS Sequoia 15.7.7

The problem seems to affect the entire system, not just one application. Apple's apps (Safari, Music, Books, System Settings, Messages, etc.) are all very slow.

When restarting the Mac (including trying different startup modes), it was taking a very long time to boot. After entering the password, the screen would stay gray for quite a while before the desktop finally appeared. I disabled all of the startup items and unplugged the Mac for a while. After doing that, it started booting normally again without the long gray screen, so I may have solved that part of the problem.

One thing that might be relevant is that my husband keeps a very large number of folders on his desktop. I'm not sure if that's contributing to the slowdown.

When I open Activity Monitor, several Apple apps and processes show "Not Responding," including System Settings, Messages, Keynote, Music, Books, and others.

At first I thought Safari was the only issue because it would freeze constantly. I tried:

• Clearing the Safari cache and browsing history.
• Deleting Safari-related files from the Library folder.

Neither of those helped. Now Chrome is also very slow, so it appears to be a system-wide problem rather than a browser issue.

The Mac has 32 GB of RAM, so I don't think memory is the bottleneck. iCleanMemory reports more than 20 GB (20,000+ MB) of available memory.

I also ran First Aid in Disk Utility, and it didn't report any problems with the startup disk.

Has anyone experienced something like this after a power outage? Could the outage have corrupted something that Disk Utility isn't detecting? Could this be related to iCloud, since many of the apps that show "Not Responding" are Apple apps?

Any suggestions would be greatly appreciated.

It’s a 2020 with the M1 chip that I got used for $396 in midtown Manhattan. Anyways, I know to get a monitor with usb c port for an adapter for HDMI cable. But what keyboard should I get or does it matter? In the meantime I’ll be using my Chromebook again. I’m on fixed income so dropping $450 to replace the laptop monitor by a reputable shop isn’t really feasible.
