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.
