So there is enough room for V-RAM, caching & paging files. Smaller 128 & 256 GB need 1/3 of the drive set aside for the OS to use and larger 512 GB & 1 TB drives 1/4 and larger 2 TB & 4 TB SSD’s only need 1/8 th. Now the last issue is how much free space your drive has. So the failing cable can in fact also be the cause here. Keep in mind when your system doesn’t have enough physical RAM for running what you are, your system will leverage the HDD/SSD as virtual RAM to make up the difference. but in a slightly different way than what is suspecting. I also think you might have a RAM issue here. When you put in the new cable place a strip of electricians tape on the uppercase when the cable crosses over to help protect it from rough surface of the aluminum, you also want to not crease the folds! You want nice arcs as the sharp folds will damage the fragile foil wires and shielding inside. Here’s the part you need: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable and here’s the IFIXIT guide MacBook Pro 13" Unibody Mid 2012 Hard Drive Cable Replacement. Keep in mind your original HDD was only a SATA II (3.0 Gb/s) in addition if you had upgraded the HDD to a SATA III (6.0 Gb/s) the data flows of the SDD are more intense than the HDD which the older cable will struggle with. I’m suspecting you have a few different issues here …įirst, your HD SATA cable needs to be replaced! The original cable is just not as good as the current one when supporting SATA III (6.0 Gb/s) SSD’s.

Is this a hardware problem- HD cable problem? SATA cable problem? A RAM issue? Or is my SSD not working despite what disk utility says?Īny help about how to resolve this would be greatly appreciated!!! I tried running AHT but it says error dec400, unable to run the AHT. I erased my SSD, verified and repaired it just in case there were issues and tried installing the OS again but it just doesn’t work. Going into to disk utility, my SSD was fine, but my original HD says SMART status failing.

I looked at the error logs, it says failed to verify installesd.dmg and it would download the chunklist again and loop through the whole process again.
MACBOOK PRO 2012 PROBLEMS INSTALL
I then tried command + R to install OS X- again, the update keeps getting stuck. Tried a couple of times, the update keeps getting stuck at around 2 minutes left. I reckon a clean install of the OS Mojave in recovery mode would help so I did exactly that. Watching videos were an issue too as the video would freeze randomly and resume playing for a while. On reboot, sometimes the flashing folder with the question mark or the no entry sign would appear but if I leave my mac for a while and restart it later, it would work with no issues. When the Mojave update came up I decided to update it but unfortunately after the update my MacBook would freeze and shut down on multiple occasions and the error log would say kernel panics (similar to what was experienced before I changed my hard drive to SSD). I have a Mid 2012 MBP, it has been working alright since 2012 but has gotten consistently slower so I replaced my hard drive to a SSD in summer 2018 and it was working fine on OS X Lion.
