Very slow Mbp mid 2012

Hi there,

I have a very slow ( like VERY) slow mbp mid 2012.
I have taken all out of it, like photos, docs, downloaded files etc..
Made a reset and re-installed with newest software and even upgraded it from 4 gb ram to 16 gb ram..

Still very slow working mbp !

Cannot see what's causing the problem when I check the activity control...

Seen threads about changing something in the "kernel", but I'm not sure that's the path to follow....

Hope some of you have inputs.

Thanks in advance.

Ole
 
Any updates? I have the same problem. I was looking to upgrade my 4Go RAM to 16Go Ram but if SSD works, I will reconsider...
 
Jowilliam unless you are actually using lots of RAM it does not as much good as most people think. 8GB will be enough for most standard uses and I would advise that amount. On the other hand the biggest bottle neck at the moment on any non SSD equipped computer is the HDD they are very slow, an SSD will make your mac feel better than new, 15 secs boot times and instant app opening combined with better performance of yosemite or el capitan with SSD's make them the best overall upgrade you can give any computer.
 
Thank you Samuelsan, I'll wait for Ole Juul... But I think you'right. I'll probably go with 8GoRam + SSD. I'll post an update as soon as I can.

I'll receive my SSD within this week... Will Update you as soon as I have installed it
 
I got my ssd in today after what felt like an eternity of slowness on my mid-2012 i7 2.9 GHz with 16GB of ram, and a clean install of el capitan I must say this thing is beastly. It starts up so fast and launches apps in a blink of an eye.
 
Put in my new ssd yesterday, but the Mac didn't recognize the ssd and not allowing partition...

Bought a Samsung 850 pro 256gb...

I'm getting to old for this S... !

Sounds like the SATA cable to the drive failing. That is probably what was originally causing the slowness, that is the danger when advice is given to upgrade something without understanding the actual issue. Two possibilities:

1. Blindly replace the cable and hope, they run about $25 from memory and its a relatively easy 20min replacement.
2. Obtain DriveDX and look for Cable CRC errors, specifically whether the count is increasing over time, that indicates interface and likely cable issues, hence replace the cable. Added cost of this route of DriveDX

You could also have run a drive speed test, that would have told us if it was running slower than expected and hence indicated a problem other than just it has an HDD fitted.

On the balance of probabilities I would swap the cable out, I'd give that >90% chance of resolving the issue.

Thanks for your input simonsi
Have been able to read El Capitan to the ssd via usb so you might be correct about the Sata cable..

However Org parts to the MBP cost around 100$ in Denmark...

Any experience on Far East models to the MBP... Price around 20$..?
