More over, when I press Shift, Control, Option and power button while charging, Magsafe turns green for 2 seconds and turn amber again. Which usually means the reset works. So the power button seems to work as well.

Any idea how to fix it? Won't turn on, no startup chime, and no light at all.

I'm new here, and i just want to be sure i don't buy anything that isn't going to work.

i won't to upgrade my SSD(128 GB) to a larger one. but when i search on the web, most of the solutions only work on a older model than mine ( model ID: 11,1).

so my question is, is it possible to upgrade my SSD on my MacbookPro 11,1 13 inch retina?

The update to Big Sur from Catalina completely failed mid-cycle and bricked my MacBook Pro that originally had Sierra on it.

I tried to get into recovery OS but couldn't even unlock the FileVault using my Apple ID correctly because of corruption.

I used find my iPhone to wipe the MacBook entirely and that triggered internet recovery mode which showed the drive had been split into three partitions. I couldn't delete them until I rebooted and triggered the Big Sur internet recovery OS by holding Option, Command, and R keys.

Then, Disk Utilities First Aid worked and let me Restore the drive, but every time I try to update via the internet it just fails.

I don't own another Mac and used TransMac to make a bootable macOS Sierra install drive. However, it is not recognized when I boot the system when I hold the Option key.

About to throw the laptop into a trash can out of frustration for what was supposed to be a good update. Issue stemmed from when macOS decided to download Big Sur & Catalina supplementary update.

The Trackpad and Keyboard of my MacBook Pro 13" Mid 2014 (A1502) just stopped working properly. Everything was fine but when I started it yesterday, the Trackpad would just respond every 20 - 30 seconds or so and then just for a few seconds. The Keyboard responds about 50% of the time but some (random) Keys won't work. Additionally, sometimes the letters appear a little later compared to when I pressed the key.

The mouse pointer works with an external USB connected mouse but this one hangs sometimes as well, but just for half a second every now and then.

I tried resetting NVRAM and PRAM and also erased the hard drive and installed Sierra completely new, but without any success. I can't imagine, it's a faulty Trackpad AND Keyboard.

I didn't spill any water over it and I didn't move it at all before the issue occurred first.

The codes given by Apple Diagnostics are:

• NDK001
• NDK003
• NDR001

I'm grateful for any help. Cheers!

Putting it in the fridge for 2 hours didn't help at all :-(

I connected a Magic Trackpad via Bluetooth that worked perfectly a few days ago but now has the same issues like the external mouse and lags every 10s for half a sec.

That's why I think the issue is probably not hardware-related but has something todo with the drivers of the periphery. What do you think?

I already installed the OS completely new without success, is there a more thorough way of putting the macbook back to factory-setup?

Thank you

I haven’t seen this one before. The left side has a black vertical band and the rest of the screen is white, Customer said the machine was working fine and she woke up to this in the morning. No spills, no drops.

It will generate a picture on an external monitor. I know how to make the external monitor the active screen from the original screen but have forgotten if there is a way to do it if you can’t get to the original display @danj can you help on this one?

UPDATE

very close examination revealed a pin hole size impact

When I check with battery health app it says the condition is good. And it has more then 200 cycles an 90% capacity.

Why the difference?

Should I replace the battery or leave it?

⟐ Answer edited January 05, 2021 at 17:04 MST

I've connected it to a external display monitor and the issue doesn't appear on it. It must be the internal display or its cable.

I’ve attached a few photos here. https://imgur.com/a/GGnq5rq

As you can see the Mojave background is red and all wacky. Images of people look distorted and the screen looks foggy (not really visible in image)

Firstly, can I put an i7 board into the case when it had an i5 in it previously?

When I'm searching ebay for "A1502 logic board i7" I get 2014 and 2015 models. Will a 2015 logic board work with the rest of my 2014 hardware, assuming both are 'A1502'?

Additionally, if I put my old SSD in the new board do I need to do any sort of formatting to get it to run properly or should it just work from the get go?

Thanks!

• MZ-JPU512T/0A6
• MZ-JPV5120/0A4
• MZ-JPV512S/0A4

and post a complete list which specific MacBook and iMad models they are compatible with?

I came across What's the difference between MZ-JPV5120/0A4 and MZ-JPV512S/0A4?, which brings me to the conclusion that the number at the very end indicates the number of "lanes" (despite the chart there, no idea what this actually means). Other than that, I wasn't able to find much info.

I havean issue with my Macbook pro retina 13 2014:

despite high CPU usage, the fan spins constantly at 1300 RPM, which causes the CPU temperature raise up to 80C.

All temperature sensors seem to work fine and I can manually adjust fan speed as well as it can be changed by MFC.

Also i tried 3 different fans and the situation doesn't change.

I tried to reset SMC, pram and to reinstall the system (was cooling down CPU manually, don't ask how)

Atm i am using MacFanControl to regulate the speed of the fan, but the issue is still present and causing some discomfort, like i can't install new OS because MFC doesn't run during OS installation and i am afraid of overheating.

Despite all components look good, the system doesn't regulate the speed of the fan.

This happened after i heavily broke my macbook and tried to repair it by replacing its aluminium body, its broken screen assembly and its noisy fan (was a bit bended which caused noise).

It is interesting that after i disconnected touchpad the fan was speeding up normally when CPU temperature was raising. The downside of this was that macbook was constantly throttling , CPU usage was 300% and everything was very slow. I had the same symptoms when camera's cable was damaged.

Can anybody help me with this please?

I haven’t been able to find this particular issue in searches and am hoping someone here might know what is happening and what i need to do to repair.

I am now only able to use it when connected to the power-cord- i gave s new battery coming to replace the current one. (Not sure if this could be related to the flickering)

Thanks in advance for all help.
