MacBook Pro Mid 2012 is very slow to respond to anything

I am working on a client’s Macbook Pro, Mid 2012 Model. i7 processor, 8 GB RAM.

It’s running OS-X High Sierra 10.13.6 prior to Mojave. I suspect is a bad SATA cable. Possibly, the Hard Drive going bad as well. It has a 750 GB storage - but there is only 65-70 GB on disk.

My client only uses it for his business. The main application he runs is QuickBooks. He creates text documents, reads email, surfs the net and that is about it,

The computer takes a long time to boot. It’s slow to respond with everything. Even the finder, clicking on menus, looking inside folders, etc … takes 5-20 seconds to respond.

Even emptying the trash. I have checked the Activity Monitor (looks normal). I have run a Hard Drive Test with Disk Utility. No errors or problems found. I have run Malware Bytes to see if there is a rogue program taking over the system. There were some things, but they are deleted. More tests finds nothing.

I checked the battery cycles (around 570) and System Info says that is normal. I’m running Apple Hardware Test on the system as I type this. It appears this model has had issues with the SATA cable that exhibits this same behavior.

I am getting ready to order an SATA cable from this site and put in a 250 GB SSD. This should make the computer much faster in my opinion.

Tell me if I am on the right track. )) Thanks for any info.

Update to all the suggestions. Success! Received the new HD cable. Installed. Followed Dan's suggestions. Installed the new Samsung SSD. Booted into recovery mode. Used Disk Utility to format the drive. Then installed Mohave. With a fairly fast internet speed and new SSD, from beginning to finish took about 25 minutes. Also, following Dan's suggestion, I used Migration Assistant to move data files, and Apps from the old HD in an external enclosure. The only problem I had was with QuickBooks. A quick search on Intuit's site, I saw info about others having the same problem - migrating from an old to new computer. Followed their steps. And now everything is working great for my client. iFixit users helped me tremendously! Thanks to all!

Hard Drives often get fragmented files which will slow the system down. You would need to use a tool which can see the fragmentation as well as fix it. I would first replace the SATA cable as you are about to do. I would place a strip of electricians tape across the uppercase where the cable crosses as the rough aluminum tends to wear the cable. Be careful in your placement as you don’t want sharp folds but smooth arcs. Many people think you can bend the cable any which way which is in fact not true! The foil conductors can be damaged as well as the shielding with the sharp folds.

After replacing the cable it when you want to run the defragmentation using a tool like this: Drive Genius 4. Even though the drive is mostly empty the scatter plot of the data blocks can cause the head assembly of the drive need to cross one side to the other which slows the reading or writing.

Replacing the HDD to a SSD will also improve performance, which is a good direction to go as well

I have found a Samsung 250 GB SSD on sale from Frys for $47. I intend to clone the existing hard drive. As mentioned, the 2012 MacBook Pro is slower than molasses. Excruciating. So, I am assuming to clone the fastest, it would be better for me to format the SSD using my personal fast MacBook Pro. Pop the SSD into the 2012. Then clone from the older HD (I have a dual USB SATA docking station) to the newly formatted SSD. This client of mine only has 65 GB TOTAL on his current HD. He is NOT a gamer. )) I am going to attempt to go to my local Apple Store and see if they have or will sell me a SATA HD internal cable. If not then order from here. Sound about right? Sorry for all the questions. I am actually pretty %#*@ good with repairs... have torn apart and repaired many PC's, Macs, laptops and desktops. But iFixit never steered me wrong. I don't mind learning better ways of doing things. ))

Given the state of the HDD I would recommend you stick with the Migration Assistant after installing the needed OS it will achieve the same actions as cloning but will work on a file by file basics Vs block which will be more sure the files are not corrupted. I'm not a lover of cloning as Ive been burnt a few times.

Dan, I have not used Migration Assistant before. Your comment makes sense. In fact, I would much rather create a fresh install of OSX and copy files over (there are not that many). I assumed Migration Assistant was for connecting two Macs or Mac to PC .... Any tutorials on how to copy from old HD to new HD? Does Migration Assistant allow that? Thx.

Here's a good write up: How to move data to your new Mac using Mountain Lion and earlier I find this T/N version a bit clearer than the newer one How to move your content to a new Mac as it offers the deeper details

Dan, installing a fresh version of OSX and copying files over is what I much prefer to do. Just opened Migration Assistant to check it out. I see where it can copy from another start-up disk. So, I will install the new SSD. Install fresh copy of OSX. Then use Migration Assistant to copy needed files over from old HD.

One concern - this client uses QuickBooks. He is not sure if he has the install CD. This is really the only reason I was thinking about cloning. Will Migration Assistant also copy over applications with all it's needed system resources? I assumed not. In addition to his slow computer issue, I really did NOT want to get into the intricacies of how QB creates, exports, backs-up data files, etc ... Looks like I just might have to.

Such slowdowns might be caused in my experience also by other possible hardware issues, battery included. You might try disconnecting the battery and run off the mains only..if that solves your issue you have your culprit.

Other sensors failures might throttle the CPU too..if you have an external bootable drive, try booting from that after disconnecting the internal hard disk cable and see what happens..if slowdown persists, you can rule out a cable failure and concentrate on other possible causes.

I did boot up from a back-up of HD in an external enclosure. It was noticably faster. Also, formatted an SSD and did a clean install of Mohave. Installed into MBP. Still slow as molasses. Just ordered the SATA cable.

Just making sure you have tried a SMC, PRAM and NVRAM reset. 99% of Mac problems can be solved by these handy tricks.

have reset the nvram/pram; and the smc. While it appears that it "may" be a little faster - it is relative to how slow it is/has been. To open a finder window took about 25 seconds. To navigate "click" the menu items in left pane (documents, pictures, music, etc...) takes between 5 -15 seconds to actually respond. Opening OSX apps ... calculator takes about 8-10 seconds to start/respond. Calendar took about 20 seconds. Shutting down apps also take a long time to respond. To quit the calendar app took over 30 seconds. By it's very nature, installing a SSD would absolutely speed things up. I am going to remove the internal HD, and boot up from a docking station. If it responds faster, then I will know it is the cable. Any other thoughts?
