I have a OCLP-ed 2012 MacBook Pro with macOS 15.7.8, and it would struggle to connect to the internet, or outright refuse to connect to the internet. Would this be a case of a bad cable connection to the Airport card, or is something wrong with the firmware? Or is the age of the Mac finally getting to the Software? I would appreciate as much help as anyone out there can give out. To add on, I would have to restart the MacBook in order to make it connect to the internet.

Many thanks!

I got a 2017 13” MacBook Pro online for parts. The fans gradually ramp up and spin at full speed when plugged in. The trackpad connector was ripped off of the board and there is no ssd. Water damage indicators are also red, but no visual marks or stains. I get no image on the display, caps lock key does not light up when I press it. When unplugged, the system immediately shuts down. Any help?

Essentially, my Macbook Pro M1 16GB 2020 (A2338) camera has stopped working. Not sure why. If I open Photo Booth, the screen is black but there is no message/warning. The camera light does NOT switch on either.

Tried the following:

• Restarting
• sudo killall VDCAssistant and AppleCameraAssitant but it says No matching processes.
• Reset the laptop (factory reset using iTunes)
• Took off the bottom cover to confirm the 4 ribbon cables were still connected from the screen

If I go to my system information, then go to my camera, it says "No video capture devices were found".

Everything else works perfectly fine so not sure why it would be the camera hardware itself.

My display backlight was working perfectly just a day ago, but ever since I connected the display into another MacBook I was testing the backlight completely stopped functioning. I already swapped the small cable that connects the display board with the logic board and have also tried SMC/PRAM reset without luck. Connecting another display to the MacBook shows nothing either (this screen was untested however). Any help?

Also, is this cable bad?

Edit to add area after cleaning with IPA:

It turns on, fan spins, but that is it nothing else happens.The sleep light is on.

I have tried, removing RAM, Swapping RAM, Without the KB connected, Without a display, different HDD / SSD, Different working HDD cable, Reset SMC, PRAM etc..... Board looks clean, no water damage evident. Owner siad it just wouldn't start anymore. It does charge the battery though.

Observations:
macOS (all versions) detects and recognises the monitors, as in the screen flickers and recognises the brand and supported modes (within adapter limits)
Same goes to the pre-boot environment
Windows does not see the external display even after manual detection. Sometimes after reboot the integrated graphics in Windows is disabled due to a problem, re-enabling it brings back proper graphics but external monitor output is still not working or being detected.
All the adapters I've bought show the MacBook Air, not the MacBook Pro, although I've seen a review of someone using it on a 2012 Unibody MacBook Pro
A while back I had a different MacBook Pro model, still 2011 but the Early 2011 one, with the Core i5 instead of the Core i7. I was given a mini DisplayPort to VGA adapter and same symptoms, macOS and preboot environment sees it, but no display out. I was told by the person that gave the adapter to me that they use it on their 2015 MacBook Air just fine with no problems.

Is there like a common fault or difference with these Unibody MacBook Pros with how they handle that specific port and why it seems to be temperamental with cheap adapters? I haven't tried the adapters I've had since other than specific Lenovo ThinkPad laptops and MacBook Airs, I haven't had the opportunity to try them.

I want to try one of the more expensive adapters but I don't want to spend money on something that is not guaranteed to work.

Let me know if there's anything I could do.

MacBook Pro Retina

All Retina screen cables with hinges are compatible.

A1425 2012L 13" Retina could be tested with 13" or 15" 2013E Display. Unfortunately, 2013/13" Display has different Camera connector.
For testing 13 and 15 inch screens of the same generation are compatible
2012-E2013 are fully compatible
L2013-2014 are fully compatible
2015 is unique

I really need to know if this display is good before we attempt a repair as otherwise it is pointless to fix ...... @danj

As a footnote,Considering that in one of the pictures it shows that the coating can peel of, I could try removing it all, and replace with another as I have 2 other fully defective display assembly's that I could try to remove the part from. Trial & error maybe or a wild possibility? Now solved.

Symptoms:

1. Battery Dead: The laptop will not turn on unless connected directly to the power adapter. The battery is not charging.
2. Peripherals Overheating: USB dongles and other peripherals become extremely hot within a short time when plugged in.
3. Electric Shock/Leakage: I feel an electric shock (tingle) when touching the aluminum case, suggesting a grounding issue or internal short circuit.

My Question: Based on these symptoms, what components should I replace?

• Is it just the battery?
• Could it be the battery connector cable or the USB-C/Charging port flex cable?
• Is the Logic Board (Motherboard) damaged and in need of replacement?

I am looking for suggestions on which specific parts to buy to fix this. Thank you!

. (I dont have a thermal camera or an external power supply) and i dont know where to go from here.]

I now see six holes in the logic board where the cable is supposed to fit. I can line them up to the cable but can't connect by pushing straight down. I have attached photos showing the condition of the board and the cable end.

Can someone confirm if the socket has been torn off the board? If so, is this repairable through micro-soldering, or does it require a logic board replacement? Not great res, I apologize.

Since then, the system has exhibited the following issues:

1. The Dock magnification is glitching; it only magnifies the icon previously hovered over rather than following the cursor.

2. I am unable to launch any applications using either the trackpad or an external mouse.

Hardware context: The laptop has 16GB of DDR3 RAM and a 250GB SSD (with 195GB free). It is currently running without a battery and has one blown speaker.

Could the damaged camera cable be causing these UI and input issues, or is this related to the OCLP installation? If it is a software issue, how can I troubleshoot or fix this?

I’m having a strange issue with my MacBook Pro display, and I’m hoping someone can help.

A few weeks ago, I noticed a couple of thin green horizontal lines starting at the bottom of the screen. Since then, more colored lines (green, pink, and other colors) have gradually appeared, and the number of lines keeps increasing day by day. The issue seems to be spreading upward from the bottom edge.

The strange part is that my MacBook has never been dropped, the display has never been hit or pressed, and I’ve never accidentally closed the lid with an object inside. It has always been handled very carefully.

Here are a few details:

• The lines are only on the built-in display.
• They started from the bottom and are slowly increasing over time.
• There was no single event that caused the problem.
• Restarting the Mac doesn’t fix it.

I’ve attached a photo of the display.

Has anyone experienced something similar?

• Is this likely a failing LCD panel, display flex cable, or display controller issue?
• Is there anything I can try before replacing the entire display?
• Could this happen without any physical damage?

Any advice or suggestions would be greatly appreciated. Thank you!

I’m looking for some help with a MacBook Pro 13” Retina (2017, Touch Bar model).

I recently replaced the battery. The replacement went smoothly, and after reconnecting everything and checking the connections multiple times, the MacBook powers on normally and correctly recognizes the new battery.

However, since the battery replacement, I’ve been experiencing the following issues:

• The keyboard does not work at all.
• The trackpad does not work and does not physically click (it feels completely locked).
• The right cooling fan does not appear to work properly.
• On every startup, the left fan immediately ramps up to a very high speed and keeps spinning loudly, regardless of system load.

The MacBook itself boots and operates normally with an external keyboard and mouse, and the battery is detected correctly by macOS.

I’ve already reopened the MacBook and checked the battery and flex cable connections, but I haven’t found anything obviously disconnected or damaged.

Has anyone experienced something similar after a battery replacement? Could this be related to the trackpad flex cable, keyboard/trackpad connector, fan connector, or perhaps a sensor that is no longer being detected?

Any suggestions would be greatly appreciated. Thanks!
