Mid 2012 Laptop Constant Crash


macrumors newbie

Hi all
I believe my logic board maybe on its way out but I just wanted to see if anyone can offer some help here.

I have a Mid 2012 MacBook Pro 13. It suffers dreadful constant crashes which sometimes messes up the OS and I have to re-install. Then I have problems there and it crashes half way through the install and I keep having to cycle round in circles until it does install without it crashing. I can't even update my OS as it does it every time and takes over a day to fix. I've had 3 crashes the last hour but then i can go for days without one. If I'm in Windows, it doesn't ever crash which is why I'm wondering if it is the logic board. I'm now on the latest Mojave. Attached below is the last crash report. Any help is much appreciated.

I’m almost certain the problem is relating to the SATA cable. It’s a very common point of failure on your model. Apple used to have a silent repair program for it.

If you haven’t already:

1) Replace the SATA cable
2) Replace the hard drive with an SSD
3) Upgrade the RAM to 8 or 16GB

Steps 2 and 3 will vastly improve system performance and longevity, whilst step 1 should fix the failure you’re having. All in all, it’ll be better than new.

OP shows 8GB, but the crash report lists the RAM as 1333 MHz.
That's probably OK, but the memory bus would be showing 1600 MHz with compatible memory. You are, at the minimum, giving away some possible speed from your Mac, when you shouldn't have to do that.
Might be a good thing to post what your RAM chips actually are, and probably consider replacing with memory from a usually good supplier, such as Crucial.
OP also shows an SSD installed. (SanDisk 240GB)
Hopefully, the SSD is in the original SATA slot, and the hard drive is in the optical drive slot - all for best results.
keysofanxiety is completely correct about the possibility of a faulty SATA cable.
The problem will not be visible to you - no apparent damage, but there can be faults in the SATA cable, where the hard drive can work OK, but an SSD can have really strange issues that can be caused by timing issues in the SATA cable. You test that out by replacing the cable.

My 2018 MBP has 12.0.4 running the same OS. Are you on a beta?
Hi all
I believe my logic board maybe on its way out but I just wanted to see if anyone can offer some help here.
I concur with the other guesses that it's probably the SATA cable that connects your disk to the main logic board. It's a common failure and inexpensive and pretty easy to replace.

I replaced the SATA cable twice on mine. They are fairly inexpensive, and not a terribly complicated job to replace. The 2012 machines are incredible and still more than serviceable with an SSD inside.

However, my SATA issues would generally manifest themselves as the machine not finding a boot drive, and not so much as a series of crashes. After the first failure I replaced the internal drive with an SSD, and partitioned and moved the spinning drive to the optical bay. I used Carbon Copy Cloner to keep a bootable copy of the SSD on one partition of the HDD in case the cable failed again to limit any downtime. The other partition housed my iTunes Library and other noncritical files/libraries.
