Somehow I completely forgot that Apple ever made a discrete GPU Mac mini. Having realized that, I looked up GPU benchmarks and found that the 6630m GPU is kind of decent. Many times mower powerful than the 320m that came before it, or the Intel HD 4000 that came after it. Based on benchmarking the 6630m vs the minimum GPU system requirements for GTA4, I should be able to play that game on it too!

Those are the specs. Now here's the reality. The mini's GPU runs really good for half a minute or so? Then the fan in the mini maxes out, and the GPU throttles so bad, the framerate tanks. IN FACT, its so bad, that I had to dial back the graphics settings in GTA San Andreas to MATCH what I play on the nVidia 320m!!! So on a Mac with over 3x the GPU performance, I'm effectively getting the exact same amount of real-world performance.

My first thought was, Windows 10 must be broken, I should revert to Windows 7!
But after continued use, I'm not sure that's the issue. The second most obvious problem might be bad thermal paste? I know that replacing thermal paste on Macs is all the rage these days, but its not usually as effective as "reddit" would make it seem. But that said, I am in a case where I'm trying to max this machine out. So maybe its worth while to pop off the heat sink, clean it all down, and put some fresh paste on it? If I do go this route, is it worth buying some fancy kind of paste, or will any new, unopened paste be fine?

Any other thoughts on what might be going on? I would be very happy if I could use this mini to play GTA:SA at full native 1080p, and if I could play GTA4 at any decent, playable graphics level.

I wanted to try my hand at replacing the thermal compound, which was looking very crusty, on my old MacBook Pro. It was my first time, so I was quite prepared for any mistakes I might make. I was doing it for the experience.

As I removed the heatsink, I pulled it sideways rather than up, knocking it against the capacitor below the CPU.

After doing some dugging, I found out that it's the C1060 capacitor. See the boardview below and the relevant extract from the schematics.

The computer works. I ran Cinebench, and the kernel didn't panic or anything. I assume it's a matter of luck.

I am considering whether to buy a heatgun myself or give it to a professional. A heatgun costs around 80€. I have asked a local professional for a quotation.

Does anyone have any insight into this problem, any recommendations? Should I take it to a professional to get it fixed? Is it worth fixing? Is it worth buying the equipment to try and do it myself?

I have a Macbook Pro from early 2011 and I had problems with the video, I took it to a technician to reball it and it supposedly worked, at the same time it failed again and this time they told me they had changed the video chip.

In the end, it failed again and when I took it to repair it again it did not work again.

I finally bought a used logic board in china and was able to successfully install it as a replacement for the deceased one.

But I have the following problems:

1 The battery or battery charger does not work so the fans run at full speed.

2 I was able to get it to boot but it does not recognize the SSD.

3 I put the original hard disk (unfortunately it had been used for a windows pc) and tried to install different versions of OS

- Yosemite USB installation (failure to finish preloading the USB, the computer restarts and the installation begins again)

- Installation via USB of El Capitan (failure to finish preloading the USB similar to Yosemite) but then I was able to install it with "Clover" and the installable image of El Capitan. The installation was successful but when the mac tries to start it reboots before finishing the progress bar with the apple at the start. This installation only works failsafe and I cannot start the diagnostic mode (D, cmd + D, option + D) nor the recovery mode (R, command + R)

- Recovery using time machine, since I have a copy of High Sierra, I recovered the complete installation but the behavior is the same. Fails to start unless in safe mode.

- Currently installing a minor version (mountain Lion) install the first stage, restart and start installing the second stage. it always restarts after 30% and starts again.

4 In the El Capitan version I uninstalled the drivers for the dedicated video card, hoping that was the problem, but I never got it to boot normally.

I also did all the possible updates and only the installation of "MacBook Pro EFI Firmware Update 2.7" fails because when the Mac restarts to do the update, it restarts again and again and only continues in safe mode. when I look for if something needs to be updated, "MacBook Pro EFI Firmware Update 2.7" reappears

Please if you can tell me what steps to follow or some guide would be saving me.

I am in Argentina and the prices to take this equipment to an official service are exorbitant and unreliable.

Hi @danj , you really blew my mind!

First of all thanks for your help and advice, in my many searches I found many of your contributions and they were always very helpful.

I read quite a bit about it and to try and rule out that this was the problem and did the following:

Using my other computer (macbook pro early 2013) and internet recovery I installed mountain lion on a 16Gb pendrive. I put it in the macbook pro 2011 and by pressing option I told it to boot from it.

To my surprise and for the first time it managed to start!

I even managed to install the update "EFI Firmware Update 2.7" ...

My joy ceased when it rebooted for no reason while trying to install the Safari update. (started downloading update and failed)

The mac rebooted again and while loading the OS it rebooted again! This behavior persists as long as a reboot failure occurs and I think I manage to stop this reboot cycle when I hold the power button and turn on again while pressing the option key to choose usb as startup.

As you had indicated to me that the cable could be the cause of the failure. Disconnect the hard drive cable from the logic board. I started again and it rebooted again :( again trying to update Safari.

Just in case, also disconnect the cable from the optical drive.

With both units disconnected it continues to fail.

Currently, it only has a 16 Gb USB as a hard drive.

Since I couldn't update Safari, I downloaded Chrome and managed to install it.

But as soon as I want to start Chrome and the icon starts jumping on the dock while loading, it restarts again ...

Here's my suspicion: Could this be a matter of memory? Currently, it has two 4Gb memories and before doing all these tests I had changed them for two 2Gb and it also failed.

Update (09/02/2021)

Here it is the report I got booting into safe mode

1) While typing the key jumps to different places in the document.

2) The battery charges to 100%, in approx 4hrs to 50% then dies to 1% shut down. Apple suggests reset SMC, But the LEFT SHIFT KEY will not reset SMC.

However, spot 1 seems to be occupied by a Torx screw. That's also the case for my laptop.

Both my laptop and online guides can't give me any idea about where the Phillips screw should go.

Thanks in advance.

I am surprised by the fact that the Phillips screw is supposed to sit on top of the Torc screw.

This is the second time I’ve replaced my battery with an ifixit battery and this is the second time this issue has came up. After replacing the battery and running the calibration cycle, I would use my laptop on its battery and somewhere around 70%-60% battery level, the battery level would just shoot down to 7%.

Initially on the first time around with replacing the battery, I just figured they sent me a faulty battery, but didn’t have time to buy another one and change it out, so i lived with the power adapter. I finally had a chance to replace it to a new battery, but the same thing just happened. Now, Im hoping to find some answers from you all if I have another faulty battery or some other insight on what it might can be.

Battery Terminal & Data PORT. On my MacBook Pro 16” M1 Max, snapped off or broke off when putting in new battery and I believe that was the reason why the battery it was not being recognized by the board because of the logic board connector,

I’m in desperate need for someone who can help me fix or find the parts name or number

(Battery Terminal & Data PORT)

because I’ve tried, can’t find or get anything

I have already:

1. Transferred the battery board data cable and ensured it is seated correctly in the ZIF connectors.

2. Verified that the T5 power connector pancake screw is snug and making a good connection.

3. Performed an SMC reset.

4. Tried leaving it on the charger to wake it from a potential deep sleep state.

Everything is snug and tight, but the new battery still shows no signs of life. Is there anything else I should check, or is it likely a defective part?

I just broke my Airport Card Antenna connector from the Airport Card. There are 2 connectors - "J1" and "J2"

J2 is fully broken from the airport card, but the WiFi is still working. Do you have any idea what is the "J2" connection for...? is it just for boost the signal ?

Thanks!

So I tried replace the battery on the MacBook Pro 2141 and the step where the battery flex cable needed to disconnected by accident I lifted the connector that snapped.

Can new connector be soldered back with ease or this one need more repair?

So, I brought to the repair shop they soldered, but claiming there is issue with motherboard - it not powering up (Please note still with old battery on laptop) but I never had any signs of motherboard going bad, it was working prior this. I asked for technical report, they refused - said we cannot provide that, our system not allowing to print report. Total bs! So first - I need that data on the laptop, so I need data extraction, or should I try something else before that. Thanks

Can you please call me I’m looking for an adapter that allows me to plug in a 2016/2017 non touch bar SSD drive to either a USB-A or USB-C port to read and test drives externally.

I would need about 10 of them.

I've torn the lid angle sensor while trying to clean the inside of my computer. I've attempted to work around this by putting the computer to sleep before closing the lid however the screen turns back on as soon as it is closed. Also strange that the screen will stay on indefinitely until the battery is dead, even though i've changed my power savings settings are to turn the display off after one minute of inactivity. Its odd because if the sensor is broken and the computer thinks that it's still open, it should turn off after inactivity. The only solution i've found is to shut the computer off before closing it which is not ideal. Finally, i've found replacement cables online however i've been reading that this will need to be calibrated by a professional? Can anyone confirm if this is true?

Thank You

Thank you all for the wealth of information. Just to provide an update to you all, i made sure to purchase a used angle sensor that was taken from a working computer and replaced it on my own. So far everything works as it should!
