Why is my MacBook taking 30 second for each action? (unresponsive)

I still using MBP Mid-2012, and it works just fine for more than 10 years until a couple of days ago. I have upgraded my storage to 500Gb SSD and also my RAM to 8GB. In the last 9 years, I almost always turned off my Mac every time I put it in my rucksack (I know it shouldn't be a problem, it is just a habit). Last week, I forgot to turn off my Mac while I commute and when I got back home and open the computer, it started to become unresponsive.

The cursor is still responsive and has no problem. However, it needs at least 20-30 seconds to respond to a single click or hover. Even to type something it takes 10-15 seconds until it appears on the screen.

I tried my best to do some possible actions I can find online to solve this. Turn off unneeded Login Items, uninstalled apps, cleaned junk, cleaned malware, and check+ and repaired the storage via Utility Disk until I decided to wipe out my SSD. It takes forever to do internet OS recovery* and install a new Catalina and I keep bumping into the same problem. I decided to reinstall the OS that came with the computer (Mountain Lion), and it's still the same. I decided to reinstall Catalina again, however, It's not getting better.

I've opened the machine, and checked for any possible physical damage to the hardware but can't find any. In addition, I installed a new pair of RAM. I run Apple Hardware Test and got the reference code ADP000.

So, probably not the OS and not the hardware? I'm literally clueless at the moment and desperate for any solution. What should I do now?

Thank you!

*I don't have a bootable OS installer

This sounds like the HD SATA cable needs replacing! The orginal HD Apple used was not able to fully saturate the HD cable, unlike your SSD! So the orginal cable wasn’t able to support the full SATA III (6.0Gb/s) it could leverage. Here’s the needed part MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable and here’s the guide to put it in MacBook Pro 13" Unibody Mid 2012 Hard Drive Cable Replacement

A second issue this system faced is the rough milling of the case left a surface which over time would wear the cable as the drive would shift about. Here’s a bit more on this issue Your Hard Drive Cable Is A Ticking Time Bomb

So place a single strip of tape under the cable to protect it from wearing. But also don’t mishandle the cable as you don’t want sharp bends as that will damage the thin foil conductors! Ideally, use a old BIC pen ink straw as a forming brake to create the bends. As the radius of the bends should not exceed the straw.

Once you replace the cable make sure you do a full backup, then wipe the drive by reformatting it and reinstall your OS and of course your backup stuff as well.

Thank you, Dan! I never thought about the cable at all since the SSD seems fine on diagnostic. That's very insightful.

I just read the article and I remember that is the reason 9 years ago my computer failed to perform and won't turn on. The Apple Genius guy told me it was something related to the flex cable. I wasn't really bothered by the reason back then since it was still covered with Apple Care. I'll give it a shot with the cable replacement (and the tape hack) and update the result. Cheers!
