Q: Macbook Pro 17 2011 completely slow, with a new SSD also

Hi all,

 

I bought a used Macbook Pro 17 Early 2011, but it is very slow on booting, installing or browsing Photos or internet, I formatted the HDD and installed MacOS Sierra and the installation took about 2 hoers till it finished, but it became slower, then I bought a new Samsung SSD but no way, the Macbook Pro still slow.

The Hardware test showed that I have one Problem with the battery.

 

I googled about the Problem and I found that maybe my Firmware is old and I think it is:

I tried to install the last version but it need OS X 10.8.5 or 10.9.5 and I installed the 10.9.5 and it took about 1 hour:

in the end the Firmware file told me that I don't need this update:

Best Regards.

    I cannot offer any definitive explanation for the battery error.  All the information displayed on your System Information>Power display looks normal.

     

    You have 'kernel task' using a lot of CPU resources.  Look at the information in this discussion, specifically Linc Davis' definition and the CNET article by Topher Kessler (an occasional participant here).

    I am wondering if there may be something wrong with your SSD.  From the recovery partition, run Disk Utility>First Aid>Repair.

     

    Last I would install the original RAM and see if that makes any difference.

     

    Ciao.

    Dear OGELTHORPE,

     

    I tried other RAMs but no different, I installed windows 7 2 times, one without bootcamp and one with, the tests show me high results for RAMs, SSD and Graphic card but low for the Processor, I made this photo before installing the graphic cards driver:

    I don't have a photo after installing the drivers but it was also above 7.0

     

    do you think I have problem in the Processor?

    when I watch it on Windows 7, any small task take minimum 30%.

     

    Best Regards

    Simply installing different RAM by itself is not a proper test.  It must be modules that conform to the specifications required for your MBP:  204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM.

     

    I am not well versed in Windows but it is my understanding that Windows can only be installed via Bootcamp.  How you were able install without Bootcamp mystifies me.

     

    You might run an Apple Hardware Test that may pick up CPU or other problems:

     

    https://support.apple.com/en-us/HT201257

     

    Note that an error free AHT is not conclusive.

     

    If the AHT does result in no errors, I think the best option becomes a visit to an Apple store genius bar.  They have better tests available than the AHT and the evaluation will be FREE.

     

    Ciao.
